Some Results on the Erdős–Faber–Lovász Conjecture
Authors: Feng Yun , Lin Wensong
Published: June 2022

Erdős–Faber–Lovász conjecture states that if a graph G is a union of the n edge-disjoint copies of complete graph Kn, that is, each pair of complete graphs has at most one shared vertex, then the chromatic number of graph G is n. In fact, we only need to consider the graphs where each pair of complete graphs has exactly one shared vertex. However, each shared vertex may be shared by more than two complete graphs. Therefore, this paper first considers the graphs where each shared vertex happens to be shared by two complete graphs, and then discusses the graphs with only one shared vertex shared by more than two complete graphs. The conjecture is correct for these two kinds of graphs in this work. Finally, the graph where each shared vertex happens to be shared by three complete graphs has been studied, and the conjecture also holds for such graphs when n=13. The graphs discussed in this paper have certain symmetric properties. The symmetry of graphs plays an important role in coloring. This work is an attempt to combine the symmetry of graphs with the coloring of graphs.
An Improved, Dual-Direction, Promoter-Driven, Reverse Genetics System for the Infectious Bursal Disease Virus (IBDV)
Authors: Hu Xifeng , Chen Zheng , Wu Xiangdong , Ding Zhen , Zeng Qinghua , Wu Huansheng
Published: June 2022

The infectious bursal disease virus (IBDV), one member of the Birnaviridae family, causes immunosuppression in young chickens by damaging the mature B cells of the bursa of Fabricius (BF), the central immune system of young chickens. The genome of IBDV is a bisegmented, double-strand RNA (dsRNA). Reverse genetics systems for IBDV allow the generation of genetically manipulated infectious virus via transfected plasmid DNA, encoding the two genomic viral RNA segments as well as major viral proteins. For this purpose, the minus-sense of both segment A and segment B are inserted into vectors between the polymerase I promoter and the corresponding terminator I. These plasmids facilitate the transcription of the viral minus-sense genome but copy the plus-sense genome as well viral protein translation depends on the activity of VP1 and VP3, when transfected into 293T cells. To further improve rescue efficiency, dual-direction promoters were generated based on the polymerase II promoter in the reverse direction in the backbone of the pCDNA3.0 vector. Therefore, the polymerase I promoter transcribes the viral minus-sense genome in the forward direction and the polymerase II promoter transcribes viral mRNA, translated into viral proteins that produce infectious IBDV. We also found that the rescue efficiency of transfecting two plasmids is significantly higher than that of transfecting four plasmids. In addition, this dual-direction promoter rescue system was used to generate R186A mutant IBDV since Arg186 is the arginine monomer-methylation site identified by LC–MS. Our data furtherly showed that the Arg186 monomer methylation mutant was due to a reduction in VP1 polymerase activity as well as virus replication, suggesting that the Arg186 methylation site is essential for IBDV replication.

Equine hepacivirus (EqHV) is the closest known genetic homologue of hepatitis C virus. An effective prophylactic vaccine is currently not available for either of these hepaciviruses. The equine as potential surrogate model for hepacivirus vaccine studies was investigated, while equine host responses following vaccination with EqHV E2 recombinant protein and subsequent EqHV inoculation were elucidated. Four ponies received prime and booster vaccinations (recombinant protein, adjuvant) four weeks apart (day −55 and −27). Two control ponies received adjuvant only. Ponies were inoculated with EqHV RNA-positive plasma on day 0. Blood samples and liver biopsies were collected over 26 weeks (day −70 to +112). Serum analyses included detection of EqHV RNA, isotypes of E2-specific immunoglobulin G (IgG), nonstructural protein 3-specific IgG, haematology, serum biochemistry, and metabolomics. Liver tissue analyses included EqHV RNA detection, RNA sequencing, histopathology, immunohistochemistry, and fluorescent in situ hybridization. Al-though vaccination did not result in complete protective immunity against experimental EqHV inoculation, the majority of vaccinated ponies cleared the serum EqHV RNA earlier than the control ponies. The majority of vaccinated ponies appeared to recover from the EqHV-associated liver insult earlier than the control ponies. The equine model shows promise as a surrogate model for future hepacivirus vaccine research.

Published: June 2022

This study explores the association between childhood immunization and gender inequality at the national level. Data for the study include annual country-level estimates of immunization among children aged 12–23 months, indicators of gender inequality, and associated factors for up to 165 countries from 2010–2019. The study examined the association between gender inequality, as measured by the gender development index and the gender inequality index, and two key outcomes: prevalence of children who received no doses of the DTP vaccine (zero-dose children) and children who received the third dose of the DTP vaccine (DTP3 coverage). Unadjusted and adjusted fractional logit regression models were used to identify the association between immunization and gender inequality. Gender inequality, as measured by the Gender Development Index, was positively and significantly associated with the proportion of zero-dose children (high inequality AOR = 1.61, 95% CI: 1.13–2.30). Consistently, full DTP3 immunization was negatively and significantly associated with gender inequality (high inequality AOR = 0.63, 95% CI: 0.46–0.86). These associations were robust to the use of an alternative gender inequality measure (the Gender Inequality Index) and were consistent across a range of model specifications controlling for demographic, economic, education, and health-related factors. Gender inequality at the national level is predictive of childhood immunization coverage, highlighting that addressing gender barriers is imperative to achieve universal coverage in immunization and to ensure that no child is left behind in routine vaccination.
Behavioral Response in Toxicity Assessment of the Insecticide Decis® 2.5 EC toward Freshwater Zooplankton
Authors: Sikorski Łukasz , Bęś Agnieszka
Published: June 2022

Chemical crop protection agents are widely applied in modern agricultural practice. As a result of surface runoff, these insecticides penetrate into rivers, ponds, and lakes, where they become a serious threat to aquatic organisms. The aim of the study was to determine the toxicity of increasing concentrations of the insecticide Decis® 2.5 EC to Daphnia magna and Heterocypris incongruens, which are components of freshwater zooplankton. The observed effect was immobilization of organisms, which were not able to swim after gentle agitation of the liquid for 15 sec. It was found that up to 135 min, increasing Decis® 2.5 EC concentrations inhibited the swimming of tested organisms. Initially, up to 135 min, Heterocypris incongruens was more sensitive to the tested insecticide. After 135 min of the experiment, ostracods acclimatized to the tested xenobiotic. However, after 360 min, the immobilization of organisms increased proportionally to the concentrations of Decis® 2.5 EC. The most toxic concentrations were 15 × 10−3% and 30 × 10−3%. The lowest observed effect concentration of Decis® 2.5 EC that reduced the swimming of daphnia and ostracod by more than 20% was >0.91 × 10−3% (0.23 mg L−1 of deltamethrin). This experiment demonstrated that Daphnia magna and Heterocypris incongruens are good bioindicators of freshwaters polluted with Decis® 2.5 EC.

The article describes a clinical case of a dissecting basilar artery aneurysm in a patient with SARS-CoV-2. The patient was treated in the infectious diseases hospital for bilateral polysegmental pneumonia on the background of COVID-19. Suddenly, a focal neurological deficit occurred and grew in dynamics in the form of abducens nerve paresis, bulbar disorders, and right-sided hemiparesis. MSCT and MSCT-angiography were performed in dynamics. During the first examination, the pathology of the cerebral vessels was not revealed, but 10 days later, there was detected a fusiform aneurysm of the basilar artery with a diverticulum, the rupture of which led to massive hemorrhage and an unfavorable treatment outcome. The patient's primary symptomatology could be due to impaired blood flow in the perforating branches in the area of the started dissection of the basilar artery.

Quelques remarques à propos des affaires des Îles Marshall concernant le désarmement nucléaire devant la CIJ : de l’infini au zéro
Authors: Sorel Jean-Marc
Published: June 2022

Les affaires opposant les Îles Marshall à trois États possédant l’arme nucléaire devant la CIJ symbolisent le fossé entre la question posée, celle de l’obligation de négocier le désarmement nucléaire sur la base du TNP ou d’obligations coutumières, et les arrêts où la Cour se juge incompétente, non pas tant en raison de l’incompétence elle-même, que de la solution pour y parvenir. Dès lors, ces arrêts paraissent à la fois décalés face à l’ampleur universelle de la question posée, mais aussi surprenants par le constat d’absence de différend entre les protagonistes et les évitements sur des points sensibles que ces arrêts contiennent, et enfin dérangeants par la manière de répondre à la question, les oppositions non voilées parmi les juges ou quelques flottements dans le raisonnement suivi. Il en résulte que la question nucléaire est depuis longtemps bien délicate pour la Cour, même si rien n’est jamais figé.

Published: June 2022

Purpose : This study aimed to investigate the effects of burnout and social support on the quality of professional life of clinical nurses during the COVID-19 crisis. Methods : This descriptive study was participants comprised 140 nurses caring for COVID-19 patients in a general hospital. Questionnaire survey data were collected between February 7, 2022 and March 4, 2022, and analyzed using SPSS 23.0. Data analysis included frequency, percentage, mean, standard deviation, independent t-test, one-way ANOVA, Pearson’s correlation, and stepwise multiple regression. Result : We found that burnout negatively correlated with compassion satisfaction and positively correlated with compassion fatigue. Social support also positively correlated with compassion satisfaction and negatively correlated with compassion fatigue. The factor most significantly affecting compassion satisfaction was job satisfaction(β＝-.31, p＜.001), fallowed by burnout(β＝-.25, p＝.002), and social support(β＝.25, p＝.001), and the explanatory power was 39%. The factor most significantly affecting compassion fatigue was burnout(β＝.54, p ＜.001), fallowed by social support(β＝-.34, p＜.001), and nursing period for patients with COVID-19(β＝-.18, p ＝.004), and the explanatory power was 56%. Conclusion : Clinical nurses require psychological and emotional support as well as active counseling programs to reduce their burnout and compassion fatigue and improve their professional quality of life. Legal and administrative systems should also ensure adequate compensation and improve the working environment for nurses in government, medical institutions and nursing organization.
Addressing Common Obstacles to Effective Shared Leadership
Authors: Atencio Chris , Herbst Nathaniel
Published: June 2022

Previous research done for a doctoral dissertation five years ago evaluated shared leadership in seven American Christian churches and ministries (Herbst, 2017). It found ten of the common benefits associated with shared leadership in the academic literature were present in these organizations. These included exceptional outcomes, enhanced decision-making, complex problem solving, creative innovation, team-member fit, team synergy, organizational vitality, healthy organizational culture, individual health, and sustained growth. It also surfaced five potential obstacles to successful shared leadership. These included the difficulty of the model, a potential lack of follow-through, a possible lack of efficiency, a general lack of acceptance of the model, and the danger of immature or usurping team members. Limitations, drawbacks, and difficulties associated with shared leadership remain understudied and insufficiently understood. The goal of this research was to help fill that gap by doing a five-year follow up investigation into each of the previously interviewed organizations. Survey results confirmed that all five obstacles had been experienced over the past five years but none had kept these organizations from continuing to effectively share leadership. Successful shared leadership, along with the benefits it proffers, is not elusive but it does require the intentional mitigation of potential pitfalls.

In compliance with applicable legislation, salary provision must be supported by evidence in the form of paperwork and other records. Several factors must be considered when determining wage to ensure that the pay is commensurate with the work performed by employees, such as attendance lists, so that employees are more encouraged to adhere to attendance policies. In this situation, the payroll accounting information system makes it easier for accountants to complete computations and keep track of everything relevant to payroll transactions. This payroll information system, on the other hand, can lead to data entry errors. If you enter the erroneous account number, especially while distributing salaries, the money could end up in someone else's account, resulting in significant losses. This study was carried out at the North Sumatra Province's Department of Communication and Information (Diskominfo). By performing direct observations and interviews with numerous employees, this study takes a descriptive qualitative method. The findings of this study show that the payroll system is still ineffective since it does not consider employee attendance hours when calculating employee salary. It would be preferable if attendance hours were factored into salary calculations, as this would encourage employees to be more punctual.
VALANGINIAN RADIOLARIANS OF NE SARDINIA (ITALY) IN THE FRAME OF THE WEISSERT EVENT
Authors: Dumitrica Paulian , Dieni Iginio , Massari Francesco
Published: June 2022

This article presents the very rich radiolarian fauna from the S’Ozzastru section of the Siniscola Marl crop-ping out in the northern part of Mt Albo massif (NE Sardinia, Italy). The formation was ascribed to the lower part of the upper Valanginian on the basis of the ammonite fauna indicating the Verrucosum Zone and the nannofossil con-tent suggesting the Zone NK3. Due to the scarcity of pantanelliids and especially of the absence of Cecrops septem-poratus, radiolarian marker of the upper Valanginian, radiolarians can only indicate a Valanginian age. Investigations for integrated litho-, bio-, and chemostratigraphy allowed the identification of the Valanginian Weissert Oceanic An-oxic Event (OAE), testified by a positive carbon isotope excursion (CIE) with values up to 2.98 ‰. Radiolarian study includes not only a determination of the species for biostratigraphic interpretations, but also a revision of the system-atics of the radiolarians occurring in the section. One new family (Crococapsidae), 3 new genera (Apiaromitra, Mi-crosandwichia and Ocellicapsa) and 43 new species are erected. The fauna has some elements in common with the Valanginian faunas from the Mediterranean area and many more with those from Japan, proving a wide circulation between the western and eastern Tethys.

Leprosy has been ofcially eliminated from India since December, 2005; still there are districts and blocks reporting high prevalence indicating
ongoing transmission. Thepresent study aimed at determining the current situation/scenario of leprosy in a tertiary level hospital in Kolkata.It is a
cross-sectional observational study carried out on patients diagnosed and registered in the leprosy clinic (May 2018-May 2020).Data regarding
clinical features, histopathological diagnosis and treatment, reactions was analyzed. Skin biopsies were taken in all cases and slit skin smear was
done. The biopsies and slit skin smear were evaluated for the type of pathology and acid fast bacilli (AFB) status. A total of 58 patients were
registered over 8months period, with M: F (4.8:1). 5child cases were reported, 44 (75.86%) were new cases, 14 (24.14%) were defaulter. Slit skin
smear showed 37 (63.79%) cases were multibacillary (MB). Lepromatous leprosy (LL) 28 (48.28%) was the most frequent morphologic type
followed by borderline tuberculoid (BT) 12 (20.69%) andtuberculoid leprosy 9 (15.52%) borderline lepromatous(BL) 4 (6.89%) cases, 5 (8.62%)

lepromatus leprosy, leprosy reactions are commonly seen as presenting features. It highlights the need for continuation of targeted leprosy control
activities and active case detection.
FLOATING ANCHORED DECOMPRESSIVE CRANIECTOMY IN PATIENTS WITH TRAUMATIC BRAIN INJURY: A CASE SERIES
Authors: Barooah Rajesh Kumar , Deka Nayan Jeet
Published: June 2022

Introduction:Raised intra cranial pressure following traumatic brain injury have been managed classically with a decompressive craniectomy
(DC). However the survivor of DC has a lot more in his hand other than the nancial burden and his own disability. Some of these complications
like subdural hygroma, syndrome of trephined and the need for subsequent cranioplasty can be reduced by the means of oating anchored DC.
Aim and objective:To design a novel method of decreasing ICP in traumatic brain injury patients and prevent the need for subsequent cranioplasty.
Materials and method
We did a case series of oating anchored decompressive craniectomy in 25 patients. Patients were selected based on CT criteria and clinical
detoriation. Midline shift of >5 mm, effacement of basal cisterns, blood volume of >25ml and fall in the GCS by more than two points or GCS <8
were selected for the study. Patients were evaluated based on Radiological improvement like improvement in the mid-line shift, opening up of
cisterns, Glasgow outcome scale (GOS) at the time of discharge, Length of stay (LOS) & Mortality rate.
Results and observation: A total of 25 cases were operated, of which 19 cases had acute SDH, 4 cases had acute SDH with multiple haemorrhagic
contusions and 2 cases had traumatic ICH (Intracerebral Haemorrhage). Overall mortality rate was 36%, LOS was 12.4 days and GOS at time of
discharge was 2.76.
Conclusion: The surgical technique is good in reducing the ICP in traumatic brain injury cases. However this cannot be applied to all cases.
Patients with only acute sdh without multiple haemorrhagic contusions are the better candidates. Still further study is required so as to come up with
preoperative criteria so that patient selection for oating anchored decompressive craniectomy can be better.

INTRODUCTION: Liver abscess, both amoebic and pyogenic, continue to be an important cause of morbidity and mortality in tropical countries.
nd India has the 2 most burden of liver abscess amongst all the other countries. The advances in radiology like ultrasonography (USG) and CT-scan
resulted in introduction of radiological guided aspiration and drainage of intra-abdominal abscesses as many cases are refractory to medical
therapy.
AIMS AND OBJECTIVES:To evaluate: demographic prole, etiology, clinical presentation and its management.
MATERIALS AND METHODS:
Study size and period: 70 cases, March 2021 – 2022
Study conducted at: S.V.PHOSPITAL, Ahmedabad
Needle aspiration Guidelines: abscess size >5cm or >65cc volume
Pig Tail Catheter drainage Guidelines: abscess size >8 cm or >120cc volume.
USG done: on Day 1,3,7,30.
Patients above 18 years and willing for long follow-up were included in study. Regular follow up with USG on every visit of the patient was done.
RESULTS: The mean hospital stay of Percutaneous aspiration (2.8 days) was less as compared to pigtail drainage (4.6 days) and hence the patient
compliance is more in aspiration. But for the complete resolution of abscess cavity especially for large abscesses pigtail drainage offers better
advantage than percutaneous needle aspiration provided the cavity is adequately liquied.
CONCLUSION: Percutaneous needle aspiration is minimally invasive and readily acceptable but not useful in large abscess. And pigtail catheter
drainage of abscess under USG guidance is better, safe and effective in larger abscesses but required longer hospital stay. As there is no signicant
difference in cavity resolution rate, Both Procedures could be used with equal efcacy in properly selected cases.

Published: June 2022

Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor1. Although the parotid gland is the most common site of
involvement, other major salivary glands and the minor salivary glands—most commonly of the palate—also can be involved. The management of
mucoepidermoid carcinoma depends on the grade of the tumor and the adequacy of resection. We present the case of a 41-year-old gentleman with
no known co-morbidities presented with swelling over right parotid region for 20 years. Supercial parotidectomy was done and the
histopathology revealed mucoepidermoid carcinoma - Warthin like variant. Extensive literature search has revealed only a few reported such cases.
Reproductive Indices of Naturally Mated and Artificially Inseminated Quail Hens (Coturnix japonica): Is Artificial Insemination of Japanese Quail Hens Feasible in a Local Setting?
Authors: Chibuogwu I.C
Published: June 2022

Naturally mated and artificially inseminated Japanese quail (Coturnix japonica) hens’ eggs reproductive indices were investigated to evaluate natural mating or artificial insemination techniques for breeding quails in local farms. A total of 141 (108 hens and 33 cocks) matured quails of about 11 weeks of age were used for the experiment, of which 54 hens were inseminated with Citric-quail egg albumen extended semen collected from 15 fertile cocks. Another 54 hens were naturally mated by another 18 fertile cocks in a ratio of one cock to three hens (1:3). Eggs collected from both naturally mated and artificially inseminated birds were incubated for 18 days. The percentage of incubated eggs that were fertile when candled on the 7th and 12th day and hatch-out analysis after the 18th day of incubation tested fertility. Hatchability was tested by the percentage number of fertile eggs that hatched. Naturally mated and artificially inseminated hens’ eggs had a fertility of 84.0 % and 73.3 %, and a hatchability of 82.5 % and 85.5 %, respectively. The study revealed no significant difference in the frequency of fertile or hatched Japanese quail eggs (χ2 cal < χ critical at 5% or 1% level of probability). Naturally mated and artificially inseminated birds had relative fertile egg rates of 53.4 % and 46.6 %, respectively, and relative egg hatching rates of 52.5% and 47.5 %, respectively. Artificial insemination had the advantage of introducing the same volume of semen to more quail hens than a single cock in a natural mating process. However, natural mating was recommended over artificial insemination in the study area because of the technical constraints that required more workforce and amenities in the insemination process. The authors recommended research on developing restraint instruments and non-electrical semen storage methods for quail birds. The authors also proposed a restraint model for quail birds
Phenotypic and Molecular Characterization of Escherichia coli Isolated from Donkeys Slaughtered in Abattoirs in Kaduna State, Nigeria
Authors: Esonu M. C.
Published: June 2022

Escherichia coli is a natural inhabitant of the gastrointestinal tract of both humans and animals. There are several strains of which some are harmless while some are pathogenic causing various fatal conditions in both humans and animals. A cross sectional study was conducted to determine the occurrence of E. coli and detection of virulent genes of E. coli isolated from liver, spleen and small intestine of donkeys slaughtered in Maraban Idah, Kaduna State, Nigeria. A total of 384 samples were collected from 128 donkeys from April to August 2018 based on owners’ consent. The samples were analyzed using standard methods of cultural enrichment, growth on selective media, biochemical test for identification and isolation of E. coli. Multiplex PCR was then used to detect presence of virulence genes in the E. coli isolates. The isolation rate was 5.2 % with organ distribution of 4.7 %. 4.7 % and 6.3 % for the intestine, liver and spleen respectively. Nineteen (19) of the 20 positive isolates profiled haboured different combinations of virulent genes viz: stx1-rfbO157-hlyA (n=2), stx1-rfbO157-eaeA-hlyA (n=6), stx1-eaeA (n=4), stx1-rfbO157 (n=1), stx1-rfbO157-eaeA (n=3), eaeA-hlyA (n=1), stx1-eaeA-hlyA (n=1) stx1-hlyA (n=1) hlyA (n=1) gene. This study showed that 60% of the isolates had the rfbO157 gene (E. coli O157 serotype), which is of great public health importance. Therefore, proper sanitation and hygienic practices should be ensured during and after slaughtering donkeys.
Seasonal Variations of Haematological and Biochemical Parameters Associated with Potential Laminitis in Apparently Healthy Horses
Authors: Ememe M. U.
Published: June 2022

Early detection of laminitis in horses is valuable as it provides information that can be used as a basis for advice to trainers of race and performance horses. The study was aimed to determine the seasonal variations in haematological and biochemical parameters of horses developing laminitis at Polo Club Port Harcourt, River State, Nigeria. A total of 18 horses were sampled during the dry season (February) and rainy season (July). The horses sampled were aged between 3 and 8 years. The hoof temperature, weight, packed cell volume (PCV), red blood cell (RBC) count, hemoglobin (Hb) concentration, total and differential leucocyte counts, glucose level and fibrinogen concentration were determined using standard methods. The mean hoof temperature of the horses was 36.1± 0.11oC and 35.6 ± 0.2 oC during the dry and rainy season respectively. The mean body weight of the horses was 323 ± 8.90 kg in dry season while that of rainy season was 330 ± 11.0 kg. Glucose concentration during the dry season (71.6 ± 1.5 dl/mg) was significantly lower (P ˂ 0.05) than that obtained during the rainy season (91.7 ± 1.9 dl/mg). Furthermore, the PCV, RBC count and Hb concentration were significantly higher (P ˂ 0.05) in the rainy season than the corresponding parameters in the dry season. Similarly, the total leucocyte, neutrophil and lymphocyte counts were significantly higher (P ˂ 0.05) during the rainy season than the dry season. It was concluded that variations on the parameters determined may aid to identify early warning signs of laminitis.
Preliminary Report on the Effects of Varied Diminazene Diaceturate Dosages and Treatment Regimens on Trypanosoma brucei Clearance and Relapse in Experimentally Infected Wistar Rats
Authors: Umeakuana P. U.
Published: June 2022

Comparison of the diminazene diaceturate (DD) varied treatment regimen in male Wistar rats experimentally infected with Trypanosoma brucei was done. Forty-nine rats were randomly assigned to seven groups of seven rats each (A – G). Group A was the uninfected untreated control while groups B – G were infected with 1.4 × 106. Groups C and D were treated with 3.5 mg/kg DD once and for five consecutive days while group B was left untreated. Groups E and F were treated with 7 mg/kg DD once and for five consecutive days while group G was treated with 7 mg/kg DD and repeated after 14 days. The effect of varied doses and treatment regimen was evaluated using parasites clearance and relapse of infection. Parasitaemia was established 4 – 9 days post infection in all groups except for one rat in Group G. Trypanosomes were cleared 3 – 5 days post treatment (PT) in all the treated groups. Trypanosomes relapsed in groups C, D, E, F, and group G on days 14, 42, 25, 56, and 39 post treatment, respectively. Relapse also occurred in about 67% of the rats in Group D and 14% of the rats in Group F within 80 days post treatment (PT). Increasing the dosage and or extending the duration of treatment with DD, marginally delayed the clearance of parasite in the infected rats but delayed the onset of relapse and reduced its occurrence in the infected rats. The curative efficacy of DD in this study appeared to be dose dependent as increasing the dosage and duration of treatment elicited a better therapeutic outcome. However, further experimental trials are imperative in rats and other animal species..
Fluid Therapy in Small Ruminants – A Review
Authors: Anaedum, A. A , Okafor R.O.S , Onah J. A
Published: June 2022

Body fluid constitutes averagely 60% of the body weight of ruminants and this must be maintained in order to ensure optimal bodily function. Several homoeostatic mechanisms go on within the body in order to keep these fluids and electrolytes relatively constant. When these mechanisms are overwhelmed, life-threatening imbalances can occur rapidly. The use of fluid therapy is viewed as a medical therapy just as important as other medications in the management of sick or debilitated livestock where anaesthesia and/or surgery is required. It therefore, becomes imperative to review its uses and effect in small ruminants. Fluid therapy in any patient should aim to; replace existing deficits, replace on-going water and electrolyte loss, meet maintenance requirements and serve as a vehicle for the infusion of certain intravenous medications. In order to ensure appropriate fluid therapy, the volume of fluid deficit, type of fluid required and the route of administration should be punctiliously considered.
