Ceftazidime-resistant Klebsiella pneumoniae and Escherichia coli isolates producing TEM-10 and TEM-43 beta-lactamases from St. Louis, Missouri.
Ceftazidime-resistant Escherichia coli and Klebsiella pneumoniae (49 and 102 isolates, respectively) were collected from Barnes-Jewish Hospital, St. Louis, Mo., from 1992 to 1996. They were uniformly resistant to ceftazidime, generally resistant to aztreonam, and variably susceptible to cefotaxime. Four representative E. coli strains and 15 Klebsiella strains were examined. From one to four bet...

متن کاملThe Prevalence of TEM and SHV Genes among Extended-Spectrum Beta-Lactamases Producing Escherichia Coli and Klebsiella Pneumoniae
Objective(s) Production of extended-spectrum beta-lactamases (ESBLs) by enteric bacteria continues to be a major problem in hospitals and community. ESBLs producing bacteria cause many serious infections including urinary tract infections, peritonitis, cholangitis and intra-abdominal abscess. The aim of this study was to determine the prevalence of ESBLs producing Escherichia coli and Klebsiel...
متن کاملStudy 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...
متن کاملPlasmid-mediated beta-lactamases in clinical isolates of Klebsiella pneumoniae and Escherichia coli resistant to ceftazidime.
Low-level transferable resistance to ceftazidime was detected in seven strains of Klebsiella pneumoniae and one strain of Escherichia coli. Six of the Klebsiella strains and the E. coli strain were shown to produce a novel beta-lactamase (CAZ-lo) with a pI of 5.6 that hydrolyzed broad-spectrum cephalosporins at low but comparable levels. One strain of K. pneumoniae was of a serotype different f...
