Abstract

In this study, we investigated the long-term trends in the epidemiology and susceptibility of bacterial enteropathogens among children in a well-defined area of adequate health standards. The study included all children younger than 14 years of age treated for enteritis at Heraklion University General Hospital on the island of Crete during the 18-year period from January 1993 to December 2010. Stool specimens were tested for Salmonella, Shigella, Campylobacter, enteropathogenic Escherichia coli (EPEC), Yersinia, and Aeromonas species. Of the 33,032 stool samples from patients of any age, 2,912 (8.82%) were positive for bacterial enteropathogens. The 1,597 isolates from children were identified as S. enterica (42.3%), Campylobacter spp. (33.6%), EPEC (17.4%), Y. enterocolitica (5.82%), A. hydrophila (0.44%), and Shigella spp. (0.38%). A decline in prevalence was observed for all bacterial enteropathogens. Taken as a total, enteropathogens were susceptible to gentamicin, ceftriaxone, ciprofloxacin, co-trimoxazole, and amoxicillin in 98.8%, 88.0%, 83.0%, 67.1%, and 59.6%, respectively. During the study period, the susceptibility rates decreased for co-trimoxazole (p < 0.0001) and ciprofloxacin (p < 0.001), and increased for amoxicillin (p < 0.0001). Our findings suggest declining long-term trends in the prevalence of bacterial enteropathogens and changes in susceptibility rates to first-line antibacterial agents. These changing trends in the long-term morbidity and susceptibility call for ongoing surveillance and tailored management.
