Fecal carriage of CTX-M β-lactamase-producing Enterobacteriaceae in nursing homes in the Kinki region of Japan.

The detection rate of CTX-M-type β-lactamase-producing Enterobacteriaceae in Japan has significantly increased. Nursing homes may be a reservoir of antibiotic-resistant bacteria. Therefore, we determined the prevalence of, and risk factors associated with, fecal carriage of CTX-M-type β-lactamase-producing Enterobacteriaceae among nursing home residents.

Prevalence of and risk factors associated with faecal carriage of CTX-M β-lactamase-producing Enterobacteriaceae in rural Thai communities.

Objectives: To determine the prevalence of CTX-M β-lactamase-producing Enterobacteriaceae and to study the risk factors associated with faecal carriage in asymptomatic rural Thai people.

Methods: In all, 417 stool samples were obtained from rural Thai people and screened for extended-spectrum β-lactamases (ESBLs) using MacConkey agar supplemented with 2 mg/L cefotaxime. Results were confirmed using cefotaxime and ceftazidime with and without clavulanic acid.

Prevalence of fecal carriage of extended-spectrum β-lactamase-producing Enterobacteriaceae among healthy adult people in Japan.

In Japan, the prevalence of extended-spectrum β-lactamase (ESBL) producers in hospital settings has shown an increasing trend. In the present study, we investigated the prevalence of the fecal carriage of ESBL-producing Enterobacteriaceae among healthy adults. Stool samples were collected for the phenotypic and genotypic identification of ESBL-producing Enterobacteriaceae.
