Identification and expression of cephamycinase bla(CMY) genes in Escherichia coli and Salmonella isolates from food animals and ground meat.

چکیده
Twenty-one Salmonella and 54 Escherichia coli isolates, recovered from food animals and retail ground meats, that exhibited decreased susceptibilities to ceftiofur and ceftriaxone were shown to possess a bla(CMY) gene. The bla(CMY-4) gene was identified in an E. coli isolate recovered from retail chicken and was further shown to be responsible for resistance to cephalothin, ampicillin, and amoxicillin-clavulanic acid and elevated MICs of ceftriaxone, cefoxitin, and ceftiofur.

Dissemination of blaCMY-2 among Escherichia coli isolates from food animals, retail ground meats, and humans in southern Taiwan.
Twenty-six Escherichia coli isolates recovered from food animal feces and retail ground meats and 14 urinary E. coli isolates from outpatients were shown to carry bla(CMY-2). Similar CMY-2-encoding plasmids were found among seven human and three ground-pork isolates. These data indicate the community spread of bla(CMY-2) in southern Taiwan.
متن کاملOccurrence and genetic characteristics of third-generation cephalosporin-resistant Escherichia coli in Swiss retail meat.
Prevalence and genetic relatedness were determined for third-generation cephalosporin-resistant Escherichia coli (3GC-R-Ec) detected in Swiss beef, veal, pork, and poultry retail meat. Samples from meat-packing plants (MPPs) processing 70% of the slaughtered animals in Switzerland were purchased at different intervals between April and June 2013 and analyzed. Sixty-nine 3GC-R-Ec isolates were o...

This study was conducted to reveal the phylogenetic background, to detect the genes encoding TEM, SHV and CTX-M-15 extended-spectrum β-lactamases (ESBL), and to analyze their distribution in phylo-groups of 150 Escherichia coli isolates from broiler chickens in Ahvaz (Southwest of Iran). Seventy- five cloacal swabs from healthy birds (fecal isolates), and 75 heart blood samples from bi...
متن کاملCharacterization of Salmonella enterica serotype newport isolated from humans and food animals.
Salmonella enterica serotype Newport isolates resistant to at least nine antimicrobials (including extended-spectrum cephalosporins), known as serotype Newport MDR-AmpC isolates, have been rapidly emerging as pathogens in both animals and humans throughout the United States. Resistance to extended-spectrum cephalosporins is associated with clinical failures, including death, in patients with sy...
متن کاملIdentification of Carbapenem Resistance Genes in Escherichia coli Isolated from Blattella germanica by Dot Blot Assay in Hamadan Hospitals, Iran – 2018
Background and Objective: Today, one of the problems of health systems is the presence of cockroaches in hospitals as insects that move freely in and out of the hospitals and are infected with pathogenic bacteria. The aim of this study was to identify carbapenem resistance genes in Escherichia coli isolated from Blattella germanica by dot blot assay in Hamadan hospitals in the west of Iran. Me...
