چکیده

One hundred fifty canine and feline Escherichia coli isolates associated with urinary tract infections were screened for the presence of extended-spectrum beta-lactamase (ESBL) genes. Out of 60 isolates suspected to be ESBL positive based on antimicrobial susceptibility testing, 11 ESBLs were identified, including one SHV-12 gene, one CTX-M-14 gene, and nine CTX-M-15 genes. This study provides the first report of CTX-M- and SHV-type ESBLs in dogs and cats in the United States.

Study of Antibiotic Susceptibility Pattern and Frequency of Extended Spectrum β-lactamases Genes TEM and SHV in Urinary Tract Isolates of Escherichia coli and Klebsiella pneumoniae in Tabriz

Background & objectives: Urinary tract infection (UTI) is one of the most common types of hu­man infections and Escherichia coli and Klebsiella pneumonia are the main causes of urinary tract infection among the gram negative bacteria. The prevalence of extended-spectrum β-lactamases (ESBLs) among these bacteria and hence resistant strains to β-lactam antibiotics have increased in recent decades...

Antibiotic Resistance Pattern and Genotype of Beta-Lactamase Producing Escherichia coli Isolates from Urinary Tract Infections in Zabol-Souteast of Iran

Introduction: Extended spectrum beta-lactamase (ESBL) producing Escherichia coli generate a major problem for clinical therapeutics and epidemiological study. The incidence of ESBL producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. The aim of this study was to determine the a...
