Authors: Lara Dalla Vecchia Beira  , Rebecca Grechuski Antunes  , Luciano Madeira
Published: October 2023

A restauração de dentes tratados endodonticamente constitui um desafio clínico em virtude da perda da estrutura dental. Para reestabelecer o suporte coronário, torna-se essencial o uso de retentores intrarradiculares. A fim de manter as estruturas dentais, suas respectivas propriedades e garantir o correto desenvolvimento das pesquisas in vitro, diferentes formas de armazenamento de dentes humanos extraídos foram estudadas para relacionar os efeitos sobre as mais diferentes propriedades dentinárias. No entanto não se encontraram estudos que avaliaram os efeitos sobre a resistência de adesão de pinos de fibra de vidro cimentados à dentina radicular. Objetivo: Realizar a análise da resistência de adesão de pinos de fibra de vidro cimentados à dentina radicular de dentes humanos extraídos, a partir do teste de pull-out, submetidos a diferentes condições de armazenamento. Material e métodos: Foram utilizados 24 dentes unirradiculares recém-extraídos, armazenados de diferentes formas, conforme segue: grupo A – armazenados em congelador de geladeira; grupo B – armazenados em formol 10% durante 15 dias; e grupo C – esterilizados em autoclave. Os canais radiculares foram preparados com limas rotatórias e obturados com guta-percha e cimento à base de óxido de zinco e eugenol. Após 24 horas realizou-se o preparo dos condutos com broca do sistema de pinos de fibra de vidro e procedeu-se a limpeza dos preparos com o uso do microscópio e pontas ultrassônicas. Em seguida, os pinos foram cimentados com cimento resinoso AllCem dual e submetidos ao teste de pull-out em uma máquina de ensaios EMIC DL2000. Resultados: Os dados foram analisados estatisticamente pelo teste não paramétrico de Kruskal Wallis, que não detectou diferenças estatisticamente significativas entre os grupos experimentais. Conclusão: A esterilização em autoclave e/ou desinfecção em formol 10% não obtiveram diferenças estatisticamente expressivas quanto à resistência de adesão por meio do teste de pull-out.

Avaliar a evidência científica disponível sobre os tratamentos de superfície dos materiais CAD-CAM híbridos e poliméricos e sua influência nas propriedades de adesão a esses materiais dentários. Material e métodos: Foram realizadas buscas nas bases de dados PubMed, Embase, Web of Science e Scopus, com início no mês de agosto até setembro de 2021. A pergunta norteadora da pesquisa foi: quais os tratamentos de superfície utilizados nos materiais CAD-CAM híbridos e poliméricos e sua influência nas propriedades de adesão a esses materiais? Incluíram-se estudos in vitro que avaliaram as propriedades de adesão dos materiais CAD-CAM após aplicação de algum tratamento de superfície. Foram excluídos estudos que utilizaram materiais que possuíam na sua composição apenas cerâmica e estudos que recorreram a tratamentos de superfície experimentais. Realizou-se análise da qualidade metodológica das pesquisas incluídas. Os dados extraídos dos resultados incluídos foram analisados qualitativamente de forma detalhada. Resultados: Após as etapas de seleção e leitura dos artigos, 31 estudos foram selecionados. O material CAD-CAM mais estudado foi a resina nanocerâmica (Lava Ultimate) e a cerâmica infiltrada por polímero (Vita Enamic). Os tratamentos mais usados para esses materiais foram o jateamento com partículas de óxido de alumínio revestidas ou não por sílica e o condicionamento com ácido fluorídrico, seguido da aplicação de um silano. As propriedades mais avaliadas nos estudos foram a rugosidade superficial e resistência de união. Conclusão: O jateamento com partículas de óxido de alumínio revestidas ou não por sílica, seguido da aplicação de um adesivo universal, parece ser o tratamento mais indicado para aumentar a rugosidade e obter adequada resistência de união aos materiais CAD/CAM poliméricos. Por outro lado, para as cerâmicas infiltradas por polímero, o uso do ácido fluorídrico, seguido pela aplicação do silano, parece ser o tratamento de superfície mais indicado.

Authors: Ingrid Daiane Vidal  , Maria Isabel Vanelli  , Luísa Helena Batista  , Alessandra Vaz Pinto Hapner  , Cristiano Miranda de Araujo  , Bianca Lopes Cavalcante-Leão
Published: October 2023

O bruxismo do sono é caracterizado pelo movimento muscular repetitivo de ranger ou apertar os dentes durante o estado de sono, sendo comum que ocorram diferentes graus de agitação e alteração da arquitetura do sono. Algumas condições sistêmicas podem estar ligadas à etiologia do bruxismo do sono, entre as quais se destacam os distúrbios otorrinolaringológicos. O bruxismo do sono tem sido frequentemente associado a distúrbios respiratórios do sono, particularmente a ronco e apneia obstrutiva do sono. Além disso, na literatura há registros de um aumento no percentual de 37% de bruxismo do sono em crianças com deficiência transversa da maxila, que é considerado um fator de risco para distúrbios respiratórios do sono. Objetivo: Relatar um caso clínico de uma paciente do sexo feminino, 7 anos, com mordida cruzada posterior bilateral, problemas respiratórios e bruxismo do sono. Relato de caso: Após o exame clínico e documentação ortodôntica, o tratamento de escolha foi a expansão rápida de maxila, normalmente utilizada para o aumento do tamanho da arcada dentária superior transversal em curto prazo. Tal tratamento provoca um posicionamento normal da língua, a diminuição da resistência e melhora a respiração nasal e, por consequência, do bruxismo. Resultados: Após o período de ativação observaram-se descruzamento bilateral, melhora na condição respiratória, do bruxismo do sono e correto selamento labial. Conclusão: Com a rápida expansão maxilar houve um aumento do tamanho da arcada dentária superior transversal, melhora respiratória, diminuição do bruxismo, com uma redução nos episódios de ranger de dentes durante o sono.

Networks for Drug Discovery or Regulatory Use
Authors: Novič Marjana
Published: October 2023

Quantitative structure - activity relationship (QSAR) modelling is widely used in
medicinal chemistry and regulatory decision making. The large amounts of data collected in recent
years in materials and life sciences projects provide a solid foundation for data-driven modelling
approaches that have fostered the development of machine learning and artificial intelligence
tools. An overview and discussion of the principles of QSAR modelling focus on the assembly
and curation of data, computation of molecular descriptor, optimization, validation, and definition
of the scope of the developed QSAR models. In this review, some examples of (Q)SAR models
based on artificial neural networks are given to demonstrate the effectiveness of nonlinear
methods for extracting information from large data sets to classify new chemicals and predict their
biological properties.

Authors: Gao Hui , Liu Hong , Hou Jingxuan , Gu Qingshan , Shi Meiqi , Wu Qingkun , Zheng Lu
Published: October 2023

Background:

Epidermal growth factor tyrosine kinase receptor (EGFR) is expressed in a
variety of tumors and has become a new target for anti-cancer drugs. In recent years, small molecule
inhibitors targeting EGFR have been reported extensively.

Objective:

To investigate the quantitative structure-activity relationship (QSAR) of a set of EGFR
inhibitors and design several new EGFR inhibitors with better efficiency and selectivity.

Methods:

The structure–activity relationship of 119 pyrimidine EGFR inhibitors were studied based
on comparative field analysis (CoMFA) and comparative molecular similarity indices analysis
(CoMISA).

Results:

In this study, performance models with high prediction ability were constructed (CoMFA
model: q2= 0.574, r2= 0.970, SEE= 0.163, F= 407.252; CoMSIA model: q2= 0.575, r2= 0.968, SEE=
0.171, F= 286.102), according to which 9 new EGFR inhibitors were designed. MD simulation (100
ns) on the docked complex of compound N7 (the most active compound) shows that the small molecule
bindswith the protein stably.

Conclusion:

The newly designed compound N7 was considered to be a promising EGFR inhibitor
with better activity than the best active compound 80, according to the results of molecular docking,
molecular dynamics, and ADMET prediction. These results will provide valuable guidance for the
design of novel EGFR inhibitors.

Published: October 2023

Background:

Avascular necrosis (AVN) is a potentially serious multifactorial disease.
In COVID-19 patients, AVN of many bones has been reported. Usually, the condition is linked to
steroid therapy. In this case report, we describe our experience with bilateral AVN of femoral
heads in an elderly patient months after being cured of COVID-19 infection without the use of
steroids.

Case Presentation:

A 68-year-old male was referred to the outpatient clinic of the rheumatology
and rehabilitation department for progressive bilateral hip pain starting on the left side 5 months
ago. An extensive review of the patient’s medical history identified documented COVID-19 infection
that required hospitalization 9 months before presentation. Multiplanar MRI with fat suppression
of both hips showed ill-defined areas of abnormal signal intensity affecting the left femoral
head, neck and intertrochanteric regions with associated subchondral fissuring and mild joint effusion.
A similar smaller area was also seen affecting the postero-superior aspect of the right femoral
head.

Conclusion:

AVN in COVID-19 patients can be encountered even in the absence of steroid therapy.
Topical Anti-ulcerogenic Effect of the Beta-adrenergic Blockers on Diabetic Foot Ulcers: Recent Advances and Future Prospectives
Authors: Singh Prateek , Sharma Shweta , Sharma Pramod Kumar , Alam Aftab
Published: October 2023

Background:

Patients with diabetes suffer from major complications like Diabetic Retinopathy, Diabetic Coronary Artery Disease, and Diabetic Foot ulcers (DFUs). Diabetes complications are a group of ailments whose recovery time is especially delayed, irrespective of the underlying reason. The longer duration of wound healing enhances the probability of problems like sepsis and amputation. The delayed healing makes it more critical for research focus. By understanding the molecular pathogenesis of diabetic wounds, it is quite easy to target the molecules involved in the healing of wounds. Recent research on beta-adrenergic blocking drugs has revealed that these classes of drugs possess therapeutic potential in the healing of DFUs. However, because the order of events in defective healing is adequately defined, it is possible to recognize moieties that are currently in the market that are recognized to aim at one or several identified molecular processes.

Objective:

The aim of this study was to explore some molecules with different therapeutic categories that have demonstrated favorable effects in improving diabetic wound healing, also called the repurposing of drugs.

Method:

Various databases like PubMed/Medline, Google Scholar and Web of Science (WoS) of all English language articles were searched, and relevant information was collected regarding the role of beta-adrenergic blockers in diabetic wounds or diabetic foot ulcers (DFUs) using the relevant keywords for the literature review.

Result:

The potential beta-blocking agents and their mechanism of action in diabetic foot ulcers were studied, and it was found that these drugs have a profound effect on diabetic foot ulcer healing as per reported literatures.

Conclusion:

There is a need to move forward from preclinical studies to clinical studies to analyze clinical findings to determine the effectiveness and safety of some beta-antagonists in diabetic foot ulcer treatment.

Authors: Adelia Sarah , Ardelia Athaya , Susetiati Devi Artami
Published: October 2023

Caused by an imbalance in the vaginal microbiome, bacterial vaginosis (BV) is among
the most commonly occurring vaginal infections in women of childbearing age. If untreated, BV
may have a detrimental impact on the obstetric and gynecological health of an individual. To date,
treatment for BV includes a regimen of antibiotics and avoidance of relevant risk factors. Since recurrence and reinfection are frequently observed in patients, pharmaceutical treatment for BV remains ineffective nevertheless. Repeated exposure to antibiotics could precipitate drug-resistant
strains. The severity of this problem leads to the emergence of non-antimicrobial therapies. This
article aims to provide a review on the types and efficacy of various alternative, non-antimicrobial
therapeutic regimens.

Published: October 2023

Background:

The COVID-19 pandemic is a real global health crisis. Its clinical
presentation has evolved over time with an increasing number of symptoms. Olfactory dysfunction
(OD) has recently been recognized as a frequent symptom relevant to screening for
COVID-19, especially in pauci-asymptomatic forms. However, the underlying mechanisms of
OD are not yet fully understood.

Aims:

To determine the prevalence of OD in healthcare workers with SARS-CoV-2 and to identify
its associated factors.

Methods:

This is a cross-sectional, analytical study, carried out during a period of six months
and including all healthcare workers at Farhat Hached Academic Hospital (Tunisia) who were
diagnosed with SARS-CoV-2 by PCR, RAT, or chest CT scan.

Results:

A total of 474 healthcare workers were included, representing a participation rate of
85.4%. The mean age was 41.02±10.67 years with a sex ratio of 0.2. The distribution of this
population by department noted that it was mainly maternity (13.9%). The most presented
workstation was nursing (31.4%). OD represented 39.2% of the reasons for consultation. Hospitalization
was indicated in 16 patients (3.4%). The average duration of hospitalization was 8.87
± 7.8 days. The average time off work was 17.04 ± 11.6 days. OD persisted for more than 90
days in 35 patients (7.4%). After multiple binary logistic regression, OD was statistically associated
with female gender (p =0.001; OR 95% CI: 2.46 [1.4-4.2]) and blue-collar occupational
category (p =0.002; OR IC95%:3.1 [1.5-6.5]). A significant association was also noted between
OD and professional seniority and absence from work duration (p =0.019; OR 95% CI: 0.97
[0.95-0.99] and p =0.03; OR 95% CI: 0.97 [0.95-0.99]) respectively.

Conclusion:

OD is common in COVID-19 patients. The identification of its associated factors
may contribute to enhancing the understanding of its mechanism and drive therapeutic options.

Published: October 2023

Pearl millet is a staple food crop in areas with drought, low soil fertility, and
higher temperatures. Fifty percent is the share of pearl millet in global millet
production. Numerous types of diseases like Blast, Rust, Bacterial blight, etc., are
targeting the leaves of the pearl millet crop at an alarming rate, resulting in reduced
yield and poor production quality. Every disease could have distinctive remedies, so,
wrong detection can result in incorrect corrective actions. Automatic detection of crop
fitness with the use of images enables taking well-timed action to improve yield and in
the meantime bring down input charges. Deep learning techniques, especially
convolutional neural networks (CNN), have made huge progress in image processing
these days. CNNs have been used in identifying and classifying different diseases
across many crops. We lack any such work in the pearl millet crop. So, to detect pearl
millet crop diseases with great confidence, we used CNN to construct a model in this
paper. Neural network models use automatic function retrieval to help in classify the
input image into the respective disease classes. Our model outcomes are very
encouraging, as we realized an accuracy of 98.08% by classifying images of pearl
millet leaves into two different categories namely: Rust and Blast.

Authors: Babych Eliza , Yarovaya Ksenia , Solodovnikova Yuliia , Son Anatoliy
Published: October 2023

Physical rehabilitation is a proven method of non-specific lower back pain treatment in contrast to manual therapy which has no evidence of clinical effectiveness. But sometimes, in the search for relief, patients develop complications resulting from the actions of unscrupulous healthcare providers in this field. A 35-year-old patient developed unbearable pain, impaired sensitivity, decreased muscle strength, stiffness in both legs, and urinary retention after rough manual-barefoot manipulation. Computed tomography scans of the cervical, thoracic, and lumbar spine regions revealed signs of hematomyelia involving the Th9-Th10, Th10-Th11, and L1-L2 spinal cord segments. After undergoing therapy with nonsteroidal anti-inflammatory drugs and glucocorticosteroids, the patient reported a significant improvement in his condition. The description of this clinical case demonstrates a complication of the manual-barefoot manipulation presenting as compressive myelopathy.

An Individualized Postoperative Pain Risk Communication Tool for Use in Pediatric Surgery: Co-Design and Usability Evaluation
Authors: Wood Michael D , West Nicholas C , Fokkens Christina , Chen Ying , Loftsgard Kent C , Cardinal Krystal , Whyte Simon D , Portales-Casamar Elodie , Görges Matthias
Published: October 2023

Background

Risk identification and communication tools have the potential to improve health care by supporting clinician-patient or family discussion of treatment risks and benefits and helping patients make more informed decisions; however, they have yet to be tailored to pediatric surgery. User-centered design principles can help to ensure the successful development and uptake of health care tools.

Objective

We aimed to develop and evaluate the usability of an easy-to-use tool to communicate a child’s risk of postoperative pain to improve informed and collaborative preoperative decision-making between clinicians and families.

Methods

With research ethics board approval, we conducted web-based co-design sessions with clinicians and family participants (people with lived surgical experience and parents of children who had recently undergone a surgical or medical procedure) at a tertiary pediatric hospital. Qualitative data from these sessions were analyzed thematically using NVivo (Lumivero) to identify design requirements to inform the iterative redesign of an existing prototype. We then evaluated the usability of our final prototype in one-to-one sessions with a new group of participants, in which we measured mental workload with the National Aeronautics and Space Administration (NASA) Task Load Index (TLX) and user satisfaction with the Post-Study System Usability Questionnaire (PSSUQ).

Results

A total of 12 participants (8 clinicians and 4 family participants) attended 5 co-design sessions. The 5 requirements were identified: (A) present risk severity descriptively and visually; (B) ensure appearance and navigation are user-friendly; (C) frame risk identification and mitigation strategies in positive terms; (D) categorize and describe risks clearly; and (E) emphasize collaboration and effective communication. A total of 12 new participants (7 clinicians and 5 family participants) completed a usability evaluation. Tasks were completed quickly (range 5-17 s) and accurately (range 11/12, 92% to 12/12, 100%), needing only 2 requests for assistance. The median (IQR) NASA TLX performance score of 78 (66-89) indicated that participants felt able to perform the required tasks, and an overall PSSUQ score of 2.1 (IQR 1.5-2.7) suggested acceptable user satisfaction with the tool.

Conclusions

The key design requirements were identified, and that guided the prototype redesign, which was positively evaluated during usability testing. Implementing a personalized risk communication tool into pediatric surgery can enhance the care process and improve informed and collaborative presurgical preparation and decision-making between clinicians and families of pediatric patients.
Behavior Change Techniques for the Maintenance of Physical Activity in Cancer (Preprint)
Authors: Edbrooke Lara , Jones Tamara L
Published: October 2023

UNSTRUCTURED

Ester et al report the findings from a 2-arm cluster randomized controlled trial nested within a hybrid effectiveness-implementation study, which involved a 12-week exercise and behavior change program for rural and remote Canadians (Exercise for Cancer to Enhance Living Well [EXCEL]). The addition of 23 weeks of app-based physical activity monitoring to the EXCEL program did not result in significant between-group differences in physical activity at 6 months. While several behavior change techniques were included in the initial 12-week intervention, additional techniques were embedded within the mobile app. However, there is currently a lack of evidence regarding how many and which behavior change techniques are the most effective for people with cancer and if these differ based on individual characteristics. Potentially, the use of the mobile app was not required in addition to the behavior change support delivered to both groups as part of the EXCEL program. Further research should involve participants who may be in most need of behavioral support, for example, those with lower levels of self-efficacy. Suggestions for future research to tailor behavior change support for people with cancer are discussed.

Mass selection is a breeding method used to increase the productivity of two Madura local maize. The study used a Randomized Complete Block Design (RCBD), repeated three times with ten genotypes of treatment. The plant material used was ten genotypes of the 0th to 4th generation mass selection on two Madura local maize (cultivars: Tambin and elos), i.e., T-C0, T-C1, T-C2, T-C3, T- C4, E-C0, E-C1, E-C2, E-C3, E-C4. Heritability values in the broad sense of the ten observed characters have a high category, ranging from 0.65-0.97. Production per hectare has a significant positive correlation with the character of ear length, ear circumference, ear diameter, seed weight per plant, and weight of 1000 seeds. Mass selection on two Madura local maize for four cycles showed an increase in production of 611.20 kg/ha or an average selection response of 145.16 in the tambin cultivar, while in the elos cultivar, there was an increase in production of 754.55 kg/ha or an average selection response of 179.21. Mass selection of tambin and elos cultivars in four cycles decreased days to tasseling by -1.33 days (the average selection response is -0.22) and -1.00 days (the average selection response is -0.16), respectively. Mass selection is an effective breeding method for assembling maize varieties with early maturity and high production on tambin and elos cultivars. Keywords: Heritability, the correlation between characters, selection response, mass selection, madura local maize.

Authors: Toka Apollinaire Njome , Ngatsi Patrice Zemko , Dida Sylvere Landry Lontsi
Published: October 2023

Fusarium oxysporum is the causative agent of tomato wilt and is an important disease of tomato crops worldwide. Management through chemical fungicides causes serious environmental damage and human health. This study assesses the antifungal potential of biochemical compounds of Azadirachta indica and Balanites aegyptiaca seeds extracts identified by GC-MS analytical method against F. oxysporum. Acetone, methanol and aqueous extracts of A. indica and B. aegyptiaca at 15, 30 and 60 μL/mL concentrations and synthetic fungicide (3.33 g/L) were tested in vitro in triplicate. Mycelial growth and Minimum inhibitory concentrations (MIC50, MIC90) were evaluated 8 days after inoculation (DAI). As results, 55 and 34 phytochemical compounds were identified in seed extracts of A. indica and B. aegyptiaca respectively. Methanol extract of A. indica and B. aegyptiaca at 60 μL/mL concentration showed a total inhibition (100%) of F. oxysporum mycelial growth. Low MIC50 values were obtained with aqueous extract of A. indica (8.77 μL/mL) and methanol extract of B. aegyptiaca (17.91 μL/mL). The tentative action mode showed that the methanol extract of both plants induced wall lysis of F. oxysporum. These results suggest that A. indica and B. aegyptiaca seed extracts have potent antifungal activity and could be used as an alternative to control F. oxysporum.

Así entonces el estudio parte de reconocer la complejidad de esta propuesta curricular que representa una nueva opción, entre otras posibles, para ofrecer una formación superior continua y de calidad. En este sentido, se revisa si la legislación universitaria da cabida a estos nuevos enfoques curriculares o fue ese el motivo de la creación de nueva normativa universitaria como es el caso del Reglamento General de Estudios Universitarios (junio 2013) y los Lineamientos Generales para el Funcionamiento de los Estudios de Licenciatura (febrero, 2015).
SPECTROSCOPIC & PHOTOMETRIC STUDY OF THE ALGOL-TYPE BINARY V1241 TAURI
Authors: Nelson R. H. , Alton K. B. , Kendurkar M.
Published: October 2023

New radial velocity (RV) data obtained at the Dominion Astrophysical Observatory (DAO) in Victoria, British Columbia along with light curve (LC) data for the Algol-type binary V1241 Tau have been simultaneously analysed with the 2003 version of the Wilson-Devinney code (WD2003). There were two distinct LC datasets: one was from the Transiting Exoplanet Survey Satellite (TESS) and the others (BVIc) from the (land-based) Desert Blooms Observatory (DBO). The TESS data were considered to have the least photometric uncertainty; consequently, we derived estimates for M1 (1.91(8) M☉), M2 (1.04(4) M☉), R1 (1.86(1) R☉), R2 (1.73(1) R☉), qWD (0.54(3)), L1 (10.7(8) L☉), and L2 (1.7(2) L☉) following simultaneous analysis (RV+LC) with the WD2003 code. Evolutionary modeling revealed that the primary star is somewhat evolved past the zero age main sequence (ZAMS) while the secondary is much evolved past the terminal age main sequence (TAMS).
SOLAR-TYPE ECLIPSING BINARY KIC 4832197: PHYSICAL PROPERTIES AND INTRINSIC VARIABILITY OF THE COMPONENTS

Published: October 2023

Comprehensive analysis of optical spectroscopy and space photometry of the solar type eclipsing binary system KIC 4832197 is presented. The system is composed of F7V + F9V components with masses of M1 = 1.16 ± 0.12 M☉, M2 = 1.07 ± 0.10 M☉ and radii of R1 = 1.26 ± 0.04 R☉, R2 = 1.03 ± 0.03 R☉. The position of the components on the Log Teff – Log L/L☉ plane suggests an age of 2.8 ± 0.8 Gyr for the system. Inspection of out-of-eclipse brightness in time reveals a wave-like variability pattern, whose amplitude and shape quickly change on order of days. Frequency analysis of this variability results in two significant peaks in the amplitude spectrum, which are interpreted as rotational modulation of spots on the components. Assuming both spots are on the same component, a lower limit for the differential rotation coeffcient is computed as k = 0.12, which is weaker compared to the solar value of k☉ = 0.189.
A PECULIAR GALAXY NEAR M104
Authors: Quiroga E.
Published: October 2023

Messier 104, NGC 4594, also known as the Sombrero Galaxy, has been extensively studied, especially its structure and stellar halo. Its abundance of globular clusters has given rise to many theories and much speculation. However, other objects in the vicinity of such a spectacular galaxy are sometimes ignored. While studying HST images available on the HST Legacy website of the halo of M104 (HST proposal 9714, PI: Keith Noll), the author observed at 12:40:07.829 -11:36:47.38 (in j2000) an object about 4 arc seconds in diameter. A study with VO tools suggests that the object is a SBc galaxy with an AGN (Seyfert).
Effect of Methanol Extracts of Arthrospira platensis on Survival and Increased Disease Resistance in Litopenaeus vannamei against Vibriosis
Authors: Al-Ghanayem Abdullah A.
Published: October 2023

Vibriosis is a common bacterial infection in shrimp that causes mortality in hatcheries and farms. Various steps have been initiated to increase the resistance against bacterial pathogens and decrease the mortality rate through improved culture conditions and feed. Arthrospira platensis (Spirulina), a blue-green alga, is a good source of protein and other nutrients and helps to improve digestion. The effects of the methanol extract of A. platensis on the survival rate and resistance against vibriosis were studied. The minimum inhibitory concentration of the extract for Vibrio species and in vivo antibacterial screening were investigated using Litopenaeus vannamei. Vibrio alginolyticus was inhibited with 2000 µg mL-1 extract and the other two species were inhibited by 1500 µg mL-1 extract. Furthermore, the mortality rate and antioxidant enzyme levels of shrimps injected with pathogens reduced and increased after treatment with the methanol extract, respectively. The survival rate of V. parahaemolyticus and V. harveyi-challenged shrimps were 33.3% and 50%, respectively, after 168 h. The survival rate of V. alginolyticus-infected shrimp reduced (16.6%) 168 h after injection. All surviving shrimp developed resistance to Vibrio pathogens. This study indicated that the bioactive compounds in A. platensis could not only effectively prevent bacterial infection, but also serve as eco-friendly and cost-effective immune stimulants.
