Out of 43 putative Vibrio species isolates obtained by culturing; 30 isolates were presumptively discriminated into Vibrio cholera (n=11), Vibrio anguillarum (n=8), Vibrio fluvialis/ Vibrio furnissii (n=4), Vibrio harveyi (Vibrio carchariae) (n=4) and Vibrio alginolyticus (n=3), but it was not initially possible to approve or repudiate that the remaining 13 isolates were Vibrio species through phenotypic characterization. By using PCR, targeting Original Research Article Abdel-Azeem et al.; BMRJ, 12(6): 1-8, 2016; Article no.BMRJ.24016 2 Vibrio-specific 16S rRNA gene, the presumptive 30 Vibrio isolates and 9 out of the remaining 13 isolates were confirmed as Vibrio species. The prevalence of Vibrio species was 37.1% among the examined fish species; 47.1%, 34.3% and 30.6% in Mulloidichthys vanicolensis, Lethrinus lentjan and Siganus rivulatus, respectively. The occurrence of Vibrio species pathogenic for aquatic animals and humans was confirmed which possess public health concerns. Also, the utility of molecular technique to improve the identification of phenotypic Vibrio like species is recommended.","PeriodicalId":9269,"journal":{"name":"British microbiology research journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81058779","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}

This bacterium has become more resistant to antibiotics to which it is often sensitive. The aim of this study was to study the evolution of E. coli resistance to antibiotics from 2009 to 2013 at the Yaoundé University Teaching Hospital. We included archived bench files containing information on patient’s demographic data and results of antimicrobial susceptibility testing. The data were analyzed using Microsoft office, Excel 2007 software and SPSS. A total of 350 strains of E. coli were collected from both hospitalized and non-hospitalized patients. The antimicrobial susceptibility was tested using 23 antibiotics from January 2009 to April 2013 at the Bacteriology Unit of the Yaounde University Teaching Hospital. We observed a decrease in the trend of the resistance to 8 of the antibiotics tested: Amoxicillin + clavulanic acid, cefuroxime, cefoxitin, imipenem, ofloxacine, colistin, gentamicin and netilmicin. Meanwhile, we noticed an increase in the trend of resistance to 15 antibiotics: Amoxicillin, cephalothin, cefoxitin, cefotaxime, ceftazidime, cefixime, cefepime, aztreonam, amikacin, nalidixic acid, norfloxacin, ciprofloxacin, trimethoprim-sulfamethoxazole, nitrofurantoin, chloramphenicol, fosfomycin). The trend observed were statistically significant, for the resistance rate to amoxicillin + clavulanic acid (P value=0.002), also to resistance rates of amikacin and cefotaxime (P-values=0.008 and 0.014 respectively). This increase in resistance over the years to most of the commonly used antibiotics has caused E. coli to be classified among multidrug resistant bacteria. In order to avoid a therapeutic impasse, it is necessary to carry out sensitization against the abusive use of antibiotics; surveillance activities for multidrug resistant bacteria and nosocomial infections should be reinforced as E. coli is one of a most common nosocomial bacteria.","PeriodicalId":9269,"journal":{"name":"British microbiology research journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75570057","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}

The possibility of transferring the pxo gene to other bacilli has recently been shown. The main aims of this study were to identify and compare the frequencies of the pxo gene in isolated bacilli members. The study examined possible pxo gene transfer from B. anthracis to other closely related members of the genus Bacillus. The findings presented here may be useful in the study of vaccination. Study Design: The study design was cross-sectional and descriptive. Sixty-five soil samples were collected from different geographical regions in Iran. Place and Duration of Study: The study was conducted in many provinces in Iran over several months. Samples were analyzed at the Mashhad University of Medical Sciences. Methodology: Organisms were isolated from the soil, and the isolation of pXO plasmid was performed. Presence of the pXO1 plasmid was confirmed by agarose gel electrophoresis. Isolated proteins from each bacillus were examined by SDS-PAGE. The limits of proteins encoded by the pxo gene were specifically located and data were statistically analyzed using excel. Results: Results showed that 13 samples out of 38 bacilli contained the plasmid of interest and protein bands related to proteins coded by the pxo gene. Conclusion: We have determined that the pXO1 plasmid has been transferred from B. anthracis to 13 other isolates of B. cereus group members in different regions in Iran. No transfer of the pXO2 plasmid was observed. This was apart from the identification of the pxo gene and its plasmids in different members of bacilli.","PeriodicalId":9269,"journal":{"name":"British microbiology research journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78717259","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}

Study Design: Cross-sectional study. Place and Duration of Study: VIAC clinic at Parirenyatwa Referral Hospital in Harare in Zimbabwe between February and April 2015. Methodology: Sexually active women were recruited and they provided their socio-demographic data and self-collected vaginal swabs. HIV status of the participants was determined. DNA was Original Research Article Matuvhunye et al.; BMRJ, 16(6): 1-9, 2016; Article no.BMRJ.28481 2 extracted from the swabs using the standard phenol-chloroform method. HPV DNA was detected using the standard consensus MY09/11-GP5+/GP6+ nested polymerase chain reaction. Amplicons were sequenced and sequences analyzed using bioinformatics tools to identify the HPV genotypes. Results: Sixty women were recruited. Their age ranged from 21-83 years, with a mean of 40.1 years. Most of the women were married and resided in the urban areas. Of the 60 participants, 50% (30/60) were HIV-positive. The prevalence of HPV genotypes in the study subjects was 56.7% (34/60). HPVs were most prevalent in women aged 30 years and below, and became less prevalent as the age increased. The predominant genotypes detected were HPV-16, -58, -52, -45, 18, -33, -51, -6, -81, -11, -70, -62, -32 and -40. Conclusion: A number of HPV genotypes were detected in half of women tested. There was no significance association between risk-factors (parity, level of education, residence, history of STI, contraceptive use and sexual debut) and HPV infection. The findings of this study showed that consensus nested PCR and DNA sequencing could be used to detect HPV genotypes in women in cervical cancer screening programs.
