Objectives To determine the prevalence of CTX-M β-lactamase-producing
Enterobacteriaceae in stool specimens obtained from healthy individuals in a rural area of …

A real-time PCR procedure targeting the gene of the molecular cochaperon DnaJ (dnaJ)
was developed for specific detection of strains belonging to the Enterobacter cloacae group …

Detection of extended-spectrum β-lactamases (ESBLs) in AmpC-producing
Enterobacteriaceae is problematic. A modification of the double-disk test (MDDT) has been …

Production of extended-spectrum β-lactamase (ESBL) is one of the most important
resistance mechanisms that hamper the antimicrobial treatment of infections caused by …

Extended-spectrum beta-lactamases (ESBLs) are a large, rapidly evolving group of
enzymes that confer resistance to oxyimino cephalosporins and monobactams and are …

Soils in household environments in low-and middle-income countries may play an important
role in the persistence, proliferation, and transmission of Escherichia coli. Our goal was to …

Extended-spectrum beta-lactamases (ESBLs) efficiently hydrolyze extended-spectrum beta-
lactams such as cefotaxime, ceftriaxone, ceftazidime, and aztreonam. ESBLs are most often …

Objective. To determine the risk factors associated with progression from colonization to
infection with health care-associated antimicrobial-nonsusceptible Enterobacteriaceae …

The prevalence of extended-spectrum β-lactamase-producing strains was demonstrated in 5
of 44 (11.4%) Escherichia coli, 17 of 43 (39.5%) Klebsiella pneumoniae, 3 of 50 (6.0%) …
