Sir, CTX-M-15 is an extended-spectrum b-lactamase (ESBL) extensively reported in humans, and in particular in Escherichia coli clones of sequence types (STs) ST131 and ST405. The blaCTX-M-15 gene has also become prevalent in Klebsiella pneumoniae, causing outbreaks in hospitals worldwide. – 4 In animals, a highly prevalent ESBL gene is the blaCTX-M-1 gene, with the blaCTX-M-15 gene also being f...

BACKGROUND Escherichia coli producing ESBL/AmpC enzymes are unwanted in animal production chains as they may pose a risk to human and animal health. Molecular characterization of plasmids and strains carrying genes that encode these enzymes is essential to understand their local and global spread. OBJECTIVES To investigate the diversity of genes, plasmids and strains in ESBL/AmpC-producing E....

Acinetobacter baumannii is a ubiquitous pathogen that has emerged as a major cause of healthcare-associated infections at Ladoke Akintola University Teaching Hospital. Isolates were assayed according to standard protocol. The isolates were subjected to molecular techniques to detect blaOXA, blaTEM, blaCTX-M, and blaSHV genes in strains of the A. baumannii isolates. The prevalence of A. baumanni...

Objective(s) Different types of extended spectrum beta-lactamases (ESBLs) are encountered in the clinical settings worldwide. There are a few studies regarding the prevalence of ESBL genes among Klebsiella pneumoniae isolates at Tehran especially those of blaPER and blaCTX. The aim of this study was to determine the prevalence of blaSHV, blaTEM ,blaPER and blaCTX genes among clinical K. pneumon...

Escherichia albertii is an emerging member of the Enterobacteriaceae causing human and animal enteric infections. Antimicrobial resistance among enteropathogens has been reported to be increasing in the past years. The purpose of this study was to investigate antibiotic resistance and resistance genes in E. albertii isolated from Zigong city, Sichuan province, China. The susceptibility to 21 an...

Studies of the transmission epidemiology of antimicrobial-resistant Escherichia coli, such as strains harboring extended-spectrum beta-lactamase (ESBL) genes, frequently use selective culture of rectal surveillance swabs to identify isolates for molecular epidemiological investigation. Typically, only single colonies are evaluated, which risks underestimating species diversity and transmission ...

Conjugative transposons in Gram-negative bacteria have a significant role the dissemination of antibiotic-resistance-conferring genes between bacteria. This study aims to genomically characterize plasmids and conjugative carrying integrons clinical isolates Klebsiella pneumoniae. The genetic composition phenotypic assessment 50 multidrug-resistant K. pneumoniae from tertiary-care hospital (SQUH...
