The objective was to determine the prevalence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in faeces from healthy Swedish preschool children and to establish whether transmission took place between children in preschools.
Diapers from children attending preschools in Uppsala city were collected during September to October 2010, and the faeces was cultured. Antibiotic profiles and carriage of CTX-M, TEM, SHV and AmpC type enzymes were determined. PCR-positive isolates were further characterized by sequencing and epidemiological typing. Statistics on antibiotic use and ESBL producers in paediatric patients at Uppsala University Hospital were extracted for comparison.
A total of 313 stool specimens were obtained, representing 24.5% of all preschool children in Uppsala city. The carriage rate of ESBL-producing Enterobacteriaceae was 2.9% among these healthy children. The corresponding figure for patients in the same age group was 8.4%. Escherichia coli with CTX-M type enzymes predominated, and only one E. coli isolate carried genes-encoding CMY. CTX-M-producing E. coli isolates with identical genotypes were found in children with no familial relation at two different preschools.
Using diapers, the prevalence of ESBL-producing Enterobacteriaceae in children was quickly established, and, most likely, a transmission of ESBL-producing E. coli was for the first time documented between children at the same preschool.
