The Burden and Genetic Variability of Extended-Spectrum ß-Lactamase (ESBL) - Producing Pathogens in Swiss Children

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified May 2009 by University Hospital, Geneva.
Recruitment status was:  Recruiting

The aim of the study is to determine the molecular epidemiology and genetic variability of ESBL-producing enterobacteriaceae (E-ESBL) among children in Switzerland and to estimate the associated clinical burden of disease.

The investigators' hypotheses are:

  1. The genetic variability (and especially the distribution of strains harbouring the CTX-M genes) among children is similar to that observed in adults;
  2. The overall burden of disease is still low in Switzerland compared to neighbouring countries. However, treatment of severe E-ESBL infections is challenging;
  3. The recommended oral treatment procedure with 3rd generation cephalosporins for febrile urinary tract infection may contribute to increased prevalence of E-ESBL in the long term.

The study is scheduled to start July 1st, 2008, and end June 30th, 2010.
