Detection of tetracycline resistant E. coli and Salmonella spp. in sewage, river, pond and swimming pool in Mymensingh, Bangladesh

Antibiotic resistant bacteria and resistance genes in the environment are major health problem globally. The present study was undertaken to detect antibiotic resistant Escherichia coli and Salmonella spp. in sewage, river, pond and swimming pool. Emphasis was given on tetracycline resistant phenotype and genotype, since, tetracycline is a widely used antibiotics. Isolation and identification of antibiotic resistant E....

Detection of mutations in ampC promoter/attenuator gene in Escherichia coli from dairy cows in Rio de Janeiro and Mato Grosso, Brazil

Escherichia coli present the ampC naturally, and the observation of phenotypical resistance to cefoxitin is related to this gene deregulation. Mutations in the regulatory region in ampC cause exaggerated expression. The most frequent alterations in the E. coli AmpC promoter/attenuator leading to this overexpression is described at the positions: -88, -82, -42, -18, -1 and +58. Mastitis studies were carried in Rio de...

Extended spectrum beta-lactamase production and plasmid mediated quinolone resistance among lactose non-fermenting nterobacteriaceae isolated from poultry sources in Calabar, Nigeria

This study investigated the co-carriage of plasmid mediated quinolone resistance (PMQR) and extended spectrum beta-lactamase (ESBL) producing lactose non-fermenting (LNF) Enterobacteriaceae isolated from poultry birds. This was a descriptive cross-sectional study carried out between September, 2016 and March, 2017. The Kirby-Bauer disk diffusion method was used to determine the antimicrobial susceptibility patterns....
