Occurrence of tetracycline resistance genes tet(M) and tet(S) in bacteria from marine aquaculture sites.
Occurrence of tetracycline resistance genes encoding ribosomal protection proteins was examined in 151 tetracycline-resistant bacterial isolates from fish and seawater at coastal aquaculture sites in Japan and Korea. The tet(M) gene was detected in 34 Japanese and Korean isolates, which included Vibrio sp., Lactococcus garvieae, Photobacterium damsela subsp. piscicida, and unidentified Gram-pos...
متن کاملTetracycline resistance mediated by tet(W), tet(M), and tet(O) genes of Bifidobacterium isolates from humans.
MICs of tetracyclines were determined for 86 human Bifidobacterium isolates and three environmental strains. The tet(O) gene was found to be absent in these isolates. tet(W) and tet(M) were found in 26 and 7%, respectively, of the Bifidobacterium isolates, and one isolate contained both genes. Chromosomal DNA hybridization showed that there was one chromosomal copy of tet(W) and/or tet(M).
متن کاملHost mutations (miaA and rpsL) reduce tetracycline resistance mediated by Tet(O) and Tet(M).
The effects of mutations in host genes on tetracycline resistance mediated by the Tet(O) and Tet(M) ribosomal protection proteins, which originated in Campylobacter spp. and Streptococcus spp., respectively, were investigated by using mutants of Salmonella typhimurium and Escherichia coli. The miaA, miaB, and miaAB double mutants of S. typhimurium specify enzymes for tRNA modification at the ad...
متن کاملPrevalence of Tetracycline Resistance Genes tet (A, B, C, 39) in Klebsiella pneumoniae Isolated from Tehran, Iran by Multiplex PCR
Background and Objective: Klebsiella pneumoniae is one of the three pathogens that has become a global disease control and treatment problem due to its resistance to common antibiotics. For this reason, it is crucial to study the genes that cause antibiotic resistance in it. Therefore, the aim of this study was to investigate the phenotypic and genotypic frequency of tetracycline resistance in ...
متن کاملEvaluation of resistance genes in Escherichia coli isolated from toilets in the Islamic Azad University, Mashhad and genome sequencing (tet B, tet A, tet R, OXA 10 and OXA 48) in tetracycline-resistant strains
Aims and Background: E. coli is a normal flora of the human and animal intestine that sometimes causes pathogenesis in the intestine and urinary tract. The aim of this study is to investigate resistance genes in E. coli isolated from toilets in the Islamic Azad University of Mashhad and perform genome sequencing in tetracycline-resistant strains. Methods: This cross-sectional study was perform...
