aim : the aims of this study were to determine the phylogenetic groups and investigate phenotypic and genotypic of esbl and mbl-producing e . coli isolates from patients with diar­rhea in kerman, southeast of iran. background : escherichia coli is detected as a significant cause of sporadic and outbreaks of diarrhea. the emergence of extended-spectrum ?-lactamases (esbls) and metallo-?-lactamas...

Background This study was designed to evaluate the current in vitro susceptibility of clinical isolates broad-spectrum β-lactam antibiotics. Methodology Bacterial isolates, cultured from 180 non-repetitive samples between April and November 2022 at three hospitals India, were used minimum inhibitory concentration (MIC) antibiotics using Epsilometer test (E-test) method. Test ceftriaxone combina...

The use of extended-spectrum cephalosporins in food animals has been suggested to increase the risk of spread of Enterobacteriaceae carrying extended-spectrum β-lactamases to humans. However, evidence that selection of extended-spectrum cephalosporin-resistant bacteria owing to the actual veterinary use of these drugs according to criteria established in cattle has not been demonstrated. In thi...

Bacterial resistance to the third-generation cephalosporin antibiotics has become a major concern for public health. This study was aimed to determine the characteristics and distribution of bla CTX-M-14, which encodes an extended-spectrum β-lactamase, in Escherichia coli isolated from Guangdong Province, China. A total of 979 E. coli isolates isolated from healthy or diseased food-producing an...

INTRODUCTION Commensal E. coli can be considered a reservoir of genes coding for antibiotic resistance that may be transmitted in hospitals by healthcare workers (HCWs). This study aimed to determine the fecal carriage rate of extended-spectrum β-lactamase (ESBL)-producing E. coli among HCWs. METHODOLOGY Stool samples were collected from 200 HCWs. Phenotypic screening for ESBL and AmpC β-lact...

the present study was conducted to detect the occurrence, serotype, genotype, phylogenetic relationship and antimicrobial resistance pattern of stec from healthy goats of west bengal, india. from the 125 faecal samples collected from healthy goats, 245 isolates were identified as escherichia coli. the e. coli harbouring any gene for shiga toxins (stx1/stx2) was detected in 36 (14.7%) of the 245...

We have investigated the antimicrobial resistance of verocytotoxin-producing Escherichia coli (VTEC) strains isolated from humans, animals, food, and the environment in Belgium. Resistance was more frequent in non-O157 strains from humans than in O157 strains from humans or other sources, and among non-O157 VTEC strains, intimin-positive strains were more resistant than intimin-negative strains...
