Antibiotic resistant bacteria are ubiquitous in the natural environment. The introduction of effluent derived antibiotic resistance genes (ARGs) into aquatic environments is of concern in the spreading of genetic risk. This study showed the prevalence of sulfonamide and tetracycline resistance genes, sul1, sul2, sul3, and tet(M), in the total bacterial assemblage and colony forming bacterial asse...

Abstract Stenotrophomonas maltophilia is an important multidrug resistant nosocomial pathogen. Trimethoprim/sulfamethoxazole (TMP/SMX) considered the drug of choice for treatment S. infections, thus emerging resistance to TMP/SMX poses a serious threat. In present study we aimed investigate frequency genes ( sul1, sul2, dfrA ), and evaluate their relatedness with integron 1 (int1), insertion se...

Despite of a high abundance antibiotics, heavy metals, and organic matters detected in the Saigon River Ho Chi Minh City, level spread antibiotic resistance genes this river are poorly understood. In study, total 10 (ARGs), including conferring to aminoglycosides (aac(6)-Ib-cr), β-lactam antibiotics (blaCTX-M, blaSHV, blaTEM), quinolones (qnrA, qnrB), sulfonamides (sul1, sul2), trimethoprim (df...

Antibiotic resistance genes (ARGs) pose a widespread concern for human health and wastewater treatment plants (WWTPs) are considered to be major source of ARG transmission. In this paper, the potential hosts genetic characteristics ARGs in influent, activated sludge effluent WWTPs Xinjiang were studied by metagenomics. Bacitracin gene (bacA), beta-lactamase (class A beta-lactamase), multidrug (...

BACKGROUND The bla NDM-1 gene in Salmonella species is mostly reported in clinical cases, but is rarely isolated from red and white meat in China. METHODS A Salmonella Indiana (S. Indiana) isolate was cultured from a chicken carcass procured from a slaughterhouse in China. Antimicrobial susceptibility was tested against a panel of agents. Whole-genome sequencing of the isolate was carried out...

Klebsiella pneumoniae is one of the most important opportunistic enteric bacteria and is a major cause of pneumonia and urinary tract infection. Serotype capsules of K1 and K2 can cause intense diseases. Acquisition of plasmid that codes the production of ESBLs confers on K. pneumoniae resistance to number of broad spectrum antibiotics posing a global public health problem. Integron is one of t...

This study was carried out to detect the distribution of antibiotic-resistant genes in Escherichia coli isolates from slaughtered commercial chickens in Iran by PCR. The investigated genes included aadA1, tet(A), tet(B), dfrA1, qnrA, aac(3)-IV, sul1, blaSHV, blaCMY, ere(A), catA1 and cmlA. According to biochemical experiments, 57 isolates from 360 chicken meat samples were recognized as E. coli...
