Original Research Article Ba et al.; BMRJ, 15(1): 1-10, 2016; Article no.BMRJ.26297 2 Materials and Methods: Seven maize storage technologies (from A to G) were selected in seven agro-ecological zones and 198 samples of stored maize were collected based on storage technologies. The presence of mold was observed in all the areas prospected in all the type of technologies used. The identification of the mycotoxins produced by mildews isolated of the stored maize has been performed by Thin Layer Chromatography. Results: Eleven (11) molds were isolated from the samples collected and three storage modes were observed. Fusarium sp, Penicillium sp and Aspergillus niger were the prevalent species with frequencies of 20.71%; 15.15% and 12.12%, respectively. Grain maize mode (55%) was the most used. Also the isolated molds have the ability to produce the toxins when the conditions are favorable. The identification of mycotoxins by Thin Layer Chromatography showed that the isolated and identified molds were producers of mycotoxins. A. parasiticus and A. flavus were not observed in technologies A and B in all the study areas. A. flavus, A. parasiticus, A. ochraceus, F. graminearum, F. oxysporum and P. roqueforti showed their ability to produce Aflatoxin B2, Aflatoxin G1, Ochratoxin A, Deoxynivalenol, moniliformin and Roquefortin C, respectively. Conclusion: These results clearly show an correlation between the technologies of storage and the contamination by the mycotoxins.","PeriodicalId":9269,"journal":{"name":"British microbiology research journal","volume":"15 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88646562","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}

Escherichia coli are the main agent of UTIs. Antibacterial resistance spreads rapidly among community acquired urinary E. coli . Objectives: The aim of this prospective study was to describe antimicrobial susceptibility profile and prevalence of multidrug resistant (MDR) urinary E. coli isolated from outpatients with community acquired UTI. Methods: Urine samples were collected from patients attending outpatient departments of University Hospitals in Egypt presented with symptoms of UTI. Samples were cultured and E. coli isolates were identified by colonial morphology, Gram stained film, and analytical profile index (API) 20E. Antibiotic sensitivity testing was performed by standard Kirby-Bauer disk diffusion method. Results: One hundred and forty one E. coli uropathogen were isolated. The highest resistance was to beta lactam antibiotics. Amoxicillin susceptibility was 2.1%. Resistance to 3 rd generation cephalosporins was (57.4%, 40.4%, 46.8% to cefotaxime, ceftazidime, and cefoperazone) respectively. The resistance to norfloxacin was (46.8%). While resistance to nitrofuantoin was (27.7%). The least resistance was to cefoperazone-sulbactam and amikacin (8.5% and 12.8% respectivelly). Most of the isolates were multidrug resistant (87.9%).

Methodology: The antimicrobial activities of hexane, methanol, chloroform, ethyl acetate and aqueous extracts of P. incana obtained from cocoa ( Theobroma cacao ) and kolanut ( Cola nitida ) trees were tested in vitro against five Gram negative and two Gram positive pathogenic bacteria; and three pathogenic fungi species using agar well diffusion technique. Qualitative and quantitative phytochemicals of the plants were determined by chemical methods. Results: Phytochemical screening of P. incana on cocoa and kolanut trees showed the presence of phytochemicals quality and quantity assessments. Varying degrees of inhibitory activities was observed with the solvent extracts of P. incana from cocoa and kolanut trees on test bacteria species while the test fungi species were resistant to all the extracts. Conclusion: This study showed that the methanol and ethyl acetate extracts of Phragmanthera incana had more antibacterial activities than other solvents.

Study Design: Cross sectional study. year study 2013 Methodology: Nasal swabs were taken from health care workers (HCWs) and in-patients and these were processed for the recovery of Staphylococcus aureus ( S. aureus ) and methicillin resistant Staphylococcus aureus (MRSA). Antimicrobial susceptibility of the isolates to various antibiotics was performed as per Clinical Laboratory Standards Institute (CLSI), guidelines and D-test done to ascertain constitutive macrolide-lincosamide-streptogramin B (cMLS B ) and inducible macrolide-lincosamide-streptogramin B ( i MLS B ) phenotype. Risk factors for their carriage were also analyzed. Statistical analysis was done using SPSS software version 16 and a P value of < 0.05 was taken as significant. Results: Higher rate of isolation of S. aureus and MRSA was seen among 480 in-patients (47.1% and 32.7% respectively) compared with 256 HCWs (32.8% and 19.1% respectively). Significant resistance (P<0.05) to clindamycin, erythromycin, ciprofloxacin, tetracycline and co-trimoxazole was seen in MRSA isolates recovered from in-patients. MRSA isolates had higher cMLS B and i MLS B resistance. Years of service and level of education in HCWs were significantly associated with MRSA carriage in them. Conclusion: Nasal-carriage of S. aureus and MRSA is common in HCWs and in-patients in our hospital. Apart from periodic screening for MRSA carriage, strict adherence to existing infection control guidelines is mandatory.","PeriodicalId":9269,"journal":{"name":"British microbiology research journal","volume":"238 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76437514","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}
