Faecal carriage of extended-spectrumβ-lactamase (ESBL)-producing enterobacteria in liver disease patients from two hospitals in Egypt and France: a comparative epidemiological study

Abstract

SUMMARYThis study aimed to assess and compare the epidemiology of faecal carriage of extended spectrumβ-lactamase-producing enterobacteria (ESBL-E) in Hepatology departments of two hospitals specializing in liver diseases, Theodor Bilharz Research Institute (TBRI) in Cairo (Egypt) and Beaujon Hospital (Bj) in Clichy (France). CTX-M groups were identified by PCR, and TEM and SHV derivatives with the check-point system. Phylogenetic groups ofE. coliwere determined by multiplex PCR, and clone ST131 by PCR of genepabB. Prevalence of ESBL-E was 77·6% (45/58) in TBRI and 6·5% (13/199) in Bj (P < 10−7). Previous hospitalization was more common (P = 0·003) in Bj patients (93%) than in TBRI patients (45%) suggesting high prevalence of ESBL-E in the Egyptian community. The presence ofE. coliB2 ST131 among ESBL-E faecalE. coliin Egypt confirms its pervasiveness in the community and raises concern regarding this highly virulent and resistant clone.
