Escherichia coli colonizing healthy children in Tunisia: High prevalence of Extra-intestinal pathovar and occurrence of non ESBL-producing ST131 clone

Escherichia coli is frequently the first bacterium which colonizes human infants. It is a lifelong colonizer of adults too [1]. It also represents the most frequent agent of extra-intestinal infections including urinary tract infection, bacteremia, pneumonia, bone and joint infections, intra-abdominal infections, and meningitis [2]. According to their capacity of intestinal colonization, commensal E. coli strains are divided into two categories; resident strains which have the ability of persistence in their hosts for many months, and transient strains which disappear from the microbiota within some weeks [3].
