title: [Clostridium difficile and its cytotoxin in the stools of young hospitalized children. Influence of antibiotic treatment].
abstract: Clostridium difficile has been searched in 153 stool samples from 138 children aged 0 to 12 months. We divided the population in two groups depending on the antibiotic treatment. We have found C difficile in 39 samples (25%). The colonization rate increases with age ranging from 5% before 1 month, to 36% between 1 and 6 months and 54% between 6 and 13 months. An environmental sampling yielded once C difficile. Contamination may be related to the environment. 29% of the isolates produced a cytopathic toxin. Toxin titers in infants' stools range from 1/160 to 1/10240. One only of these children had diarrhea. C difficile and its toxin does not seem to infer any signs of enteric illness with infants. The results obtained with the group of non treated infants are not significantly different from the ones of the other group: the colonization rates are 21% in the non treated group and 29% in the other group. The rate of strains yielding a cytophatic toxin is similar in the 2 groups. It seems reasonable to agree that antibiotics do not influence the settlement of C difficile in infants' intestine.
