Key Points

This research aims to characterize extended-spectrum beta-lactamase-producing Escherichia coli strains in community fecal samples.
Fecal samples were collected from the community in Sivas, Türkiye.
Molecular detection of ESBL genes was performed using multiplex PCR.
Clonal relatedness was evaluated through ERIC-PCR.
10% of the fecal samples contained ESBL-producing Escherichia coli.
Among 50 isolates, 5 (10%) were identified as the ST131 clone.
ISOLATES were grouped into 15 different clusters.

Abstract

BACKGROUNDS: (ESBL-Ec) strains isolated from community fecal samples. METHODS: genes was investigated by multiplex PCR. The ST131 clone was detected by PCR and Multi Locus Sequence Typing analyses. Clonal relatedness among ESBL-Ec strains was evaluated using ERIC-PCR. RESULTS: 10%. ESBL-Ec isolates were grouped into 15 clusters, and 5 (10%) of 50 isolates were identified as the ST131 clone. CONCLUSION: ST131 clone.
