 The global prevalence of hepatitis C is estimated at 1%, with a variable distribution in different regions of the world, sometimes even within the same country.
 General objective: To help improve the biological diagnosis and prevention of HCV infections in the urban commune of Kindia.
 Methodology: The urban commune of Kindia was used as the study area. This prospective and descriptive study was carried out at the Institut de Recherche en Biologie Appliquée de Guinée (IRBAG) from June to December 2022. The biomaterial consists of 3,000 blood samples taken from patients attending consultations at health facilities. The Immuno-Enzymatic technique (ELISA) was used to test for anti-HCV antibodies.
 Results: In the course of our work, out of 3,000 samples taken from patients admitted to health facilities, 78 cases tested positive for the anti-HCV antibody, representing a carriage rate of 2.6%. Females were the most affected, with 50 positive cases (1.67%). The 31-40 age group had the highest anti-HCV antibody carriage rate, at 0.70%.
 Conclusion: All socio-professional groups are affected by this infection, but to varying degrees. Despite our efforts, hepatitis C virus infection remains a major concern, as there is currently no vaccine and existing treatments are expensive and inaccessible to middle-income countries.","PeriodicalId":18450,"journal":{"name":"Microbiology Research Journal International","volume":"22 S1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135934655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sub-Saharan Africa, with a prevalence rate between 8 and 18%, is a highly endemic region.
 Objective: To help protect the health of students through awareness and screening for the hepatitis B virus.
 Methods: This is a prospective and descriptive longitudinal study which lasted one month, from February 15 to March 15, 2023.
 Results: Among the 200 students screened for the hepatitis B virus, men were more represented (80.50%) than women (19.50%), with a m/f sex ratio of 4.12 in favor of men. The 17-25 age group was the largest (77%), followed by the 26-33 age group (19.5%), the 34-41 age group (3%) and the 42+ age group (0.5%). 32% of students say they have good knowledge of the hepatitis B virus, compared to 68% who say they have little knowledge. The majority reported television as a source (75.5%), followed by radio (16%), school (4%), newspapers (2.5%) and social media (2%). The vast majority identified sexual transmission (89%), followed by blood (9.5%) and saliva (1.5%). In terms of risky practices, the majority of students identify prostitution (82.5%), followed by tattooing (9%), piercing (5%) and acupuncture (3.5%). Concerning knowledge of the hepatitis B vaccine, the majority of students (67.5%) say they do not know the vaccine against the hepatitis B virus, compared to 32.5% who say they know the vaccine. The HBV prevalence test showed 11% carriage compared to 89% negative tests. Transaminase tests on positive cases gave 63.63% normal ALT versus 36.36% elevated ALT; 72.72% normal AST versus 27.27% high AST. Carriage was higher in men (86.36%) than in women (13.63%). Single students were the most represented with 95.45%, compared to 4.55% for married students. Students from the Technical Laboratory and Mechanical Design and Manufacturing Departments were the most represented with 27.27% each. They were followed by those of the Biomedical Equipment Technology and Computer Engineering Departments with 18.18% each. Finally, the Energy Department was the least represented in this series with 9.09%.
 Conclusion: This study showed that the hepatitis B virus is present at the Mamou Higher Institute of Technology. It is therefore important to introduce it into secondary school programs to improve knowledge of the hepatitis B virus in Guinea.","PeriodicalId":18450,"journal":{"name":"Microbiology Research Journal International","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136381630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

 Methodology: Sequences for analysis were sampled from the GISAID initiative’s open-access SARS-CoV-2 genome database. We selected high-quality nucleotide sequences submitted by Delaware labs between March 18 and April 14, 2021, an important period of 4 weeks which saw the Alpha variant spread rapidly in the Delaware population.

Our previous research identified 12 potential antibiotic-producing bacteria from natural habitats and obtained their diameters of inhibition in preliminary crowded plates. The potential candidates were further challenged with some pathogenic microbes by the Agar-well diffusion technique to test their strength. The results showed that the diameter of inhibition of the potential antibiotic-producing isolates obtained at the crowded plate technique level was not a predictor of the potency of potential antibiotic-producing bacteria (rs = 0.52, P = 0.08). In summary, the selection of potent candidate microbes for the development of new antimicrobial compounds against multidrug-resistant pathogens cannot be determined based on the diameter of inhibition in a preliminary investigation using the crowded plate technique.

The prevalence of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae in community settings remains undetermined. In order to obtain data on ESBL enterobacteria, 265 stool samples were collected from August 2019 to February 2020 from individuals residing in the urban districts of Abidjan and attending medical consultations at the Institut Pasteur de Côte d'Ivoire. Isolates belonging to family Enterobacteriaceae were isolated on MacConkey and identified using the API 20E galerie and antibiotic susceptibility was determined using Clinical Laboratory Standard Institute disc diffusion method. Detection of extended spectrum β-lactamases (TEM, SHV, GES, PER, VEB, CTXM 1, CTXM 2, CTXM 8 and CTXM 9) was done by simplex and multiplex PCR. The human stools strains consisted of 513 species of Enterobacteria multidrug resistants. Among the 513 strains, 75 (14.6%) of the enterobacterial strains produced ESBLs, while 438 (85.4%) produced high-level cephalosporinases. Enterobacteria producing extended-spectrum β-lactamase we dominated by the species Escherichia coli (46.7%), Klebsiella pneumoniae (17.3%), Enterobacter cloacae (13.3%), Enterobacter aerogenes (6.7%), Proteus mirabilis (6.7%), Klebsiella oxytoca (4%), Proteus vulgaris (2.7%), Citrobacter koseri (1.3%), and Citrobacter freundii (1.3%). Strains were resistant (100%) to antibiotics from beta-lactam family (penicillin with inhibitor, monobactam, cephalosporin) but low level resistant (1,3%) was observed to carbapenem (imipénème, méropénème, Ertapenem). The rate of resistance to quinolones and aminoglycosides were respectively between 22.9% - 43.3% and 7.9-35.1%. The resistance genes TEM, SHV, CTXM 1, CTXM 2, CTXM 8 and CTXM 9 were detected. No GES and PER genes were not detected.
