Authors: Nkemdilim Nwaka Orjioke , Onyemelukwe Felicia Ngozi
Published: January 2024

Wound infections caused by drug-resistant Proteus species pose a global health threat, including in Nigeria. This study aimed to determine the prevalence, antibiotic susceptibility, and ESBL production in Proteus species from wound infections in a Nigerian tertiary hospital. The descriptive cross-sectional study spanned eight months (September 2022 to April 2023) at Alex-Ekwueme Federal University Teaching Hospital in Ebonyi State, Nigeria. 322 wound samples from in and out-patients were analyzed using disc diffusion for antimicrobial susceptibility, the double disc-synergy test for phenotypic ESBL production, and PCR for ESBL gene screening. Out of the 322 samples, 61 (18.9%) were Proteus species, with 43 (70.5%) identified as Proteus mirabilis and 18 (29.5%) as Proteus vulgaris. Surgical wounds had the highest number of Proteus isolates (41%), followed by wound ulcers (34.4%), and trauma wounds had the least (24.68%). The relationships between wound type and Proteus prevalence, patient category and Proteus prevalence, and age of patients and Proteus prevalence were not statistically significant (p > 0.05). However, the relationship between patients' sex and Proteus prevalence was significant, with males (73.8%) having higher isolates than females (26.2%). Ceftazidime and levofloxacin showed the highest activity against Proteus isolates, while nalidixic acid, cefotaxime, imipenem, and nitrofurantoin exhibited the highest resistance. There were significant differences in antibiotic sensitivity and resistance between P. mirabilis and P. vulgaris (p < 0.05). 80% of Proteus isolates were multidrug-resistant (MDR), and this relationship was statistically significant (p < 0.05). 55% of P. mirabilis and 55.6% of P. vulgaris were confirmed to produce ESBLs. PCR detected ESBL genes: TEM (37.5%), CTX-M (37.5%), and SHV (25.0%). Proteus isolates from the studied wound infections demonstrated a high level of multidrug resistance, and ESBL genes were detected.

The use of bio fertilizers is important for sustainable agriculture and the use of nodule bacteria, p-solubilizing bacteria, K-mobilizing bacteria and PGPR is an appropriate way to enhance germination percentage, plant growth and yield. This study tested the effects of a bacterial consortia (Bio-Release KONCERT) containing Rhizobium sp, Bradyrhizobium sp, Bacillus sp. and Pseudomonas sp. for the combined effect on Soybean crop. Experiment designed for seed treatment of soybean during kharif 2022-2023, to check the efficacy of consortia product at different doses (5, 10, 15, and 20 ml/kg of seeds) with RDF, local strain as check and control for comparing the data. Seed treatment observed uniform in all the treated seeds with different range of doses. Treating seeds with Bio-release KONCERT @ 20 ml kg-1 of seeds was found superior in enhancing the soybean growth parameters, soil biological activity in terms of soil enzymes, physiological parameters and yield attributes. This is found to be at par with Bio-release KONCERT @ 15 ml kg-1 of seeds and Bio-release KONCERT @ 10 ml kg-1 seeds. Compared with the non-inoculated seeds, application of Bio-release KONCERT observed superior results in all concentrations. This bio fertilizer which significantly promoted plant growth, nodulation, nitrogen fixation, nutrient uptakes, and seed yield in soybean. Use of bio fertilizers can be reducing the application of chemical fertilizer in soybean production.

Marine organisms are a great source of bioactive substances. Due to the increasing number of structurally unique and biomedically intriguing natural products that are being isolated from marine sources, the area of marine natural products has been rising. In the present study the antimicrobial activity of the mud crab (Scylla serrata) was investigated. In this study mud crab (Scylla serrata) was collected from mangroves of Karwar, west coast of Karnataka-India, and haemolymph was extracted and examined for bioactivity against E.faecalis strains. The antibiotic gentamycin was used along with the least dilution of 10µl along with the strains. The haemolymph extract was added of dilution 20µl and the pure culture was of 20µl respectively. The results showed that the size of the colony as compared to the antibiotic gentamycin and haemolymph extract with E. faecalis strains were showing decreased in the cell size as compared to the standard culture (E. faecalis) they appeared in the scanning electron microscopic images. Hence the present study shows that the haemolymph of the mud crab has potential antibiotics.
Extraction and Stability Test of Betacyanin Pigment in Dragon Fruit Skin (Hylocereus polyrhizus) as an Alternative to 2% Eosin Dyes in Examination of Soil Transmitted Helminth Worm Eggs
Authors: Rahayu Yanti , Christiani T. Arniat
Published: January 2024

Worm eggs are revealed to be colorless upon direct inspection, making them challenging to observe under a microscope. An easy technique for studying worm eggs is to utilize Eosin 2%, which is typically used in medical research and diagnostics. Eosin has some drawbacks, including a high price tag and environmentally hazardous ingredients. Consider using the skin of dragon fruits as a source of dye. The red pigment betacyanin gives dragon fruit skin its color. The intention was to determine if intestinal nematode worm egg coloration could be substituted with dragon fruit peel (Hylocereus polyrhizus). The red dragon fruit skin was extracted with ethanol as a solvent and 2% eosin as a reference to create the dye for this experimental study. Using ethanol solvent to dye feces preparations from dragon fruit peel extract demonstrates the possibility of doing so. Extract from the peel of dragon fruit shows promise as a coloring agent. As a result, 2% eosin can be replaced with dragon fruit peel extract (Hylocereus polyrhizus) when studying worm eggs.
Isolation, Characterization, Identification, Cataloguing and Fatty Acid Methyl Ester Analysis (FAME) of Some Bacteria from Selected Wetlands of North Bihar using the MIDI Sherlock Microbial Identification System
Authors: Anand Kumar , Pandey Gaurav Kumar
Published: January 2024

FAME analysis is used as a first line bacterial species identification method. Currently, this analysis is done by commercial systems such as Sherlock Microbial Identification (MIS, Microbial ID, Inc (MIDI), Newark, Delaware, U.S.A. However, the identification libraries of this system are not adaptable to the very rapidly changing and expanding bacterial taxonomy. This problem can be solved by the application of machine learning techniques, which are mathematical models that can learn from experience. Training these models with up to date information can very rapidly be achieved, and are, therefore very suitable to solve the present identification problem. Objective: The present paper deals with the detailed study on FAME analysis of four strains of bacterial genera Bacillus with MTCC no.9479, 9523, 9524 & 9526 and one actinomycetes of Nocardiopsis with MTCC no. 9525 from some selected wetlands of North Bihar. It also emphasizes on the detailed study of Similarity Index (SI) which expresses how closely the fatty acid composition of an unknown compares with the mean fatty acid composition of the strains used to create the library entry listed as its match. Methods: The fatty acids were extracted by a procedure which consists of saponification in diliute sodium hydroxide/methanol solution followed by derivatization with dilute hydrochloric acid/methanol solution to give the respective methyl esters (FAMEs). The FAMEs were then extracted from the aqueous phase by the use of an organic solvent and the resulting extract was analyzed by GLC. Results: Strain SM8 showed a S.I. value of 0.021. Strain SM10 showed a S.I. value of 0.058 and 0.048. Strain SM2A showed a S.I. value of 0.413 and 0.253 & also 0.120 and 0.112 for different entry names in the library. Strain SM18A showed a S.I. value of 0.491 and 0.445. Strain BC7A showed a S.I. value of 0.376, 0.369 and 0.308. Conclusions: After the extensive study on the morphological, phyico-chemical and biochemical aspects of microbes isolated from selected wetlands of North Bihar, 5 test isolates were selected for FAME analysis. It was concluded that strain SM18A can be considered as good library comparisons. As compared to SM18A, rest three starins viz SM8, SM10 and SM2A could not be considered as good library comparisons. Strain BC7A could be considered as a good match, but an atypical strain.

Published: January 2024

The effect of different biological and chemical nematicide cycles per year or their alternation was compared on banana (Musa AAA cv. Williams) root weight, root nematode control and crop yield in a commercial banana plantation in Ecuador testing 11 treatments in a randomized complete block design with five replicates. Treatments consisted of the rotation of two or three chemicals or even the rotation of four biological nematicide cycles by year or the rotation of chemical and biological nematicides in the year plus the untreated control. Averaging the 24 root nematode samplings, the rotation of two and three chemical nematicide cycles by year reduced R. similis (P= 0.0347) by 25 and 23%, Helicotylenchus spp. (P= 0.0009) by 31 and 18% and total nematodes (P= 0.0074) by 28 and 21%, respectively. The rotation of four biological nematicide cycles by year drops R. similis between 10 and 28%, Helicotylenchus spp. between 5 and 21% and total nematode between 5 and 23%. Although there is substantial, positive literature on nematode control with biological products, for us is the first time that some reduction was observed. Given the COVID-19 pandemic, it was not possible to do successive harvests, but at the final harvest, from 23 to 25 months after first treatment application, a difference in yield (P< 0.0001) was observed. The highest number of boxes per hectare per year was found in the treatment with 4 cycles by year of SeaMaxx® + Cronox® with 4149 followed closely by two chemical nematicides cycles by year with 4122 boxes of 18.14 kg. The additional net income in the treatments that increased yield, deducted the cost of packing for each additional box and the treatment cost was between US $327 and $3420 ha-1 year-1 24 months after the first treatment was applied. However, the net profit for every dollar invested in nematode control was higher with two chemical nematicides with $20.2 compared to $6.9 returned for the four cycles of SeaMaxx® + Cronox® due to frequent of application and higher treatment cost.

Published: January 2024

An invitro compatibility studies were conducted with Trichoderma harzianum and some commonly used chemical pesticides. The experiment was laid out in Completely Randomized Design (CRD) with four replications and seven treatments of fungicides, seven treatments of herbicides and seven treatments of insecticides on biocontrol agents T.harzianum. The fungicide ametoctradin + diamethomorph was found moderately toxic, while carbendazim + mancozeb, copper oxychloride, azoxystrobin + tebuconazole, captan and thiophenate methyl, proved toxic. Among the herbicides, carfentrazone ethyl was found compatible and glyphosate was proved slightly toxic. oxyflourofen and metribuzin are moderately toxic. The herbicides, sulfentrazone + clomazone and fomesafen + flauzifop-p-butyl, were incompatible. Insecticides, imidachloprid, acetamiprid, spinosad, imamectin benzoate and chlorantraniliprole, were found compatible whereas thimethoxam + lambda cyhalothrin was found slightly toxic.Some chemical pesticides did not affected the growth and development of T harzianum. Hence combination of such chemical pesticides with biocontrol agents can provide an additive or synergistic effect in the control of diseases and pests. These chemical pesticides and biocontrol agents can be used in an integrated pest management programme.

Published: January 2024

The dependence on chemical fertilizers for meeting plant nutrient needs has precipitated declines in soil health and microbial diversity degradation. Enhanced soil health and diverse rhizosphere microbial populations are said to contribute for sustainable agricultural ecosystem. Among the nutrients, nitrogen (N), phosphorous (P), and potassium (K) are crucial and are considered as primary elements. Although there is presence of N, P, and K in the environment, most of it is unavailable for plant absorption. Hence, microbes play a pivotal role in rendering these elements accessible to plants by their natural processes, reducing reliance on chemical fertilizers. Amid diverse experiments subjecting various microorganisms for crop growth and yield, selection of highly compatible and productive microbial consortia holds significant importance. The present investigation was aimed to isolate nitrogen fixing bacteria, phosphate-solubilizing bacteria, and potash mobilizing bacteria from wheat rhizosphere soil, assessing for their in vitro capabilities to fix, solubilize or mobilize, and function as a compatible consortium. They were subjected to biochemical and molecular characterizations for identification. Further, the consortium was used to assess its efficacy to influence wheat crop growth, nutrient uptake, crop yield, and soil health. The distinguished isolates- AZ-II, P-III, and K-II with highest nitrogen fixing capability (148.65 μg of nitrogen/mg of carbon used), phosphate solubilizing ability (33.45%), and potash mobilizing ability (41.33 μg ml-1) respectively were identified as Azotobacter chroococcum, Bacillus subtilis, and Pseudomonas fluorescens. The consortium was formulated and 2 x 107cfu g-1 of lignite powder was added as carrier material for seed treatment. The results showed that among eight treatments, the treatment with consortium of Azotobacter sp., PSB, and KMB + 75% recommended dose of fertilizer showed significant influence on crop growth, yield, soil health and microbial population. It showed highest germination, plant height, root length, dry weight of shoot and roots at earhead formation and harvest stage of the crop, number of panicles, 1000 seed weight, seed yield, NPK uptake and population of Azotobacter, PSB and KMB at flowering stage of wheat.

Authors: Nair T. Bhaskaran , K. Rajendran Radhika , Deepak K. S. , Deepa D.
Published: January 2024

Staphylococcus epidermidis is the most common normal flora of human skin. There is a delicate balance between skin barrier and innate immunity to maintain healthy skin and disturbance of the balance can predispose the host to a number of cutaneous and systemic infections. Aim-The present study is intended to find out the frequency of Staphylococcus epidermidis (S. epidermidis) of the patient normal flora causing skin infections by comparing the antibiotic sensitivity pattern of the strains isolated from clinically proven cases and strains from the healthy skin sites of the same patient. Methodology-Two types of S. epidermidis strains were collected, fifty strains isolated from clinically and microbiologically proven skin infections and fifty S. epidermidis strains isolated from the healthy skin of the same patient. Strains were stored in nutrient agar slopes at 40 C. Antibiotic sensitivity of these two groups of strains were performed on Mueller Hinton agar by standard Kirby-Bauer method and the antibiogram was compared to find out the frequency at which same strains of patient’s skin flora is isolated from active skin infections. Result- The strains of S. epidermidis from lesions exhibited high resistance against penicillin 87%, ampicillin 64%, erythromycin 64%, clindamycin 60% and ciprofloxacin 52% respectively. Linezolid and amoxiclav were the two antibiotics to which maximum strains of S. epidermidis from lesion was sensitive, 92% each. Increased resistance rate 60% was observed against clindamycin. Statistically significant (p-value < 0.05) difference in antibiogram of two groups S. epidermidis indicate that S. epidermidis strains of patient may not always cause wound infection, instead either the strains acquired extra virulence among the skin flora or strains acquired from external source establishes wound infection. Methicillin resistance was 8% among strains from lesion compared to zero percent among skin flora strains. Conclusion-It is observed that majority of the S. epidermidis strains isolated from skin infection exhibited higher rate of drug resistance compared to the strains isolated from the healthy skin of the same patient.-So it can be concluded that majority of wound infection caused by S. epidermidis is not directly derived from the skin flora, instead either the infective strains evolved from skin flora or acquired from exogenous source. Probably different strains of S. epidermidis present on the skin which acquire virulence properties cause infection.

Annual production of plastic has increased the 390.7 million metric tons in 2021 and plastic’s reprocessing has all but its sustainable solution for disposal of plastic waste has been unsuccessful. Plastic materials (fragments) are continuously accumulating in the environment, like, in sea, soil, air, rivers as well as oceans. Microplastic contamination is becoming a major concern worldwide. Nowadays, scientists are developing sustainable idea for the degradation of plastic waste with the help of microorganisms. In biodegradation of microplastics by microorganisms like fungi and bacteria are playing vital role in breaking-downs of the plastic polymers in simpler form and after that plastics are biologically degraded. Microorganisms (Pseudomonas sp., Rhodococcus sp., Bacillus sp., Zelerionmaritimum, Microalgae) that can degrade the different types of regular used synthetic plastics. The bacterial and fungal species produced Biosurfactants which helps the degradation process rapidly.

Cassava is an important staple grown worldwide for its edible leaves and roots. African cassava mosaic virus (ACMV) is the most important disease infecting this crop that reduces yield and quality. This study was conducted to determine the effect of ACMV infection on nutritional components of some cassava cultivars. The experiment was carried out at the University of Ibadan, Teaching and Research Farms. It was a randomized complete block design with four replicates using resistant, moderately resistant and susceptible cultivars. Proximate analysis was done to evaluate these nutritional components. Disease incidence and severity were highest for the susceptible [Index of Symptom Severity (ISS) =3.57 ± 0.01] cultivar and lowest for the resistant (1.36 ± 0.05) nine months after planting. Cyanide content was 37.1% for the resistant plants and 78.3% for the susceptible. Fibre and fat contents decrease significantly for infected plants compared to the uninfected irrespective of the cultivar. A decrease of 2.68% in protein content and an increase in biomass of 21.43% was noted for infected resistant plant compared to the uninfected. Index of Symptom Severity (ISS) and protein/sugar contents of cassava tubers were significantly positively correlated (P=0.05) on dry weight basis. There was significant negative correlation between starch/sugar and dry matter/moisture content of cassava tubers (r=0.9 and r=-0.8) respectively. On fresh weight basis, there was a highly significant negative correlation between ISS and moisture content (r=-0.6). Starch content was significantly positively correlated at P=0.05. Cyanide and dry matter contents had significant positive correlation (r=0.9, P=0.05). ACMV has an adverse effect on the nutritional components of cassava and therefore virus resistant cultivars should be used for planting.

Formulation of nutri-dense pancake mix was studied for enhancing the nutritive value of the traditionally prepared rice based pancake in Assam. Twelve formulations of pancake mixes were developed substituting 50 per cent rice flour with soybean seed flour, amaranth seed flour, mushroom powder and garden cress seed powder in three different sets. The developed formulations were subjected to sensory evaluation and the most acceptable three variations were selected one from each set along with a control (rice flour alone) for further analysis of physical parameters, functional properties and storage study. Data obtained were subjected to completely randomized design (CRD). The moisture content, free fatty acid and peroxide value increased significantly from day 15 to day 30. The moisture content, free fatty acid and peroxide value were almost found to be non-significant due to different pancake mixes. At 15th day, PG1 scored highest in colour, taste, texture and overall acceptability while PM1 scored highest in appearance and flavour. The mean scores of microbial study of the nutri-dense pancake mixes stored in laminated aluminium foil zip lock pouches at refrigerated temperature of 4ºC changed significantly from 0th day to 30th day. It was observed that at day 30, the total bacterial count exceeded the acceptable limit of ≤100000 cfu/g as per WHO guideline 1998 signaling the end of shelf-life of the pancake mixes by day 15.
