Isolation frequency of enteropathogens from pediatric diarrheal stool in Surabaya, Indonesia: a five year hospital based study.

In order to increase our knowledge of the epidemiology for our patient population, we retrospectively analyzed the data obtained from stool samples received at Tropical Disease Research Center, Airlangga University during a five year period. Isolation frequency of enteropathogens from diarrheal stools from 1993 to 1997 were examined in Surabaya, Indonesia. A total of 1, 477 hospitalized pediatric patients under 2 years of age with acute diarrhea were enrolled. Bacterial enteropathogens other than Campylobacter jejuni and Clostridium difficile were positive cumulatively in 1, 086 cases out of 1, 477 (73.5%), and the annual isolation frequency ranged from 61.1% to 82.4%. Rotavirus was detected cumulatively in 408 cases out of 1, 184 examined (34.5%), and 210 cases of 408 (51.5%) were co-infected with diarrheagenic Escherichia coli. Generally, diarrheagenic E. coli were dominant isolates (53.8%) while Vibrio cholerae Ol, Aeromonas hydrophila, Salmonella spp. and Shigella spp. were also isolated from the patients with lower frequencies.
