In vitro conjugation kinetics of AmpC, broad spectrum and extended-spectrum beta-lactamase-producing Escherichia coli donors and various Enterobacteriaceae recipients.

ABSTRACT:

Background

Extended spectrum beta-lactamase (ESBL)-producing enterobacteria pose a major hazard to public health. Due to the possibility of genetic transfer, ESBL genes might spread to pathogenic enterobacterial strains. Thus, information on possible genetic transfer between enterobacteria is of high interest. It was therefore the aim of this in vitro study to screen the capacity of a wide range of Enterobacteriaceae for differences in conjugation at different time points with five ESBL-producing Escherichia coli strains.

Results

Conjugation frequencies for five potential E. coli donor strains producing the enzymes CTX-M-1, CTX-M-15, SHV-12, TEM-1, TEM-52 and CMY-2, and six potential recipient strains commonly detected in the gastrointestinal tract of poultry (E. coli, Serra
