Abstract

Background: The spectrum of bacteria causing diarrhea is highly affected by geographic area, sanitation, travel, food consumption, and previous antibiotic use. A nationwide databank for stool cultures is undeveloped. The aim of our study was to investigate the current prevalence of gastroenteritis bacterial pathogens in Korea.

Methods: We requested microbiological data via questionnaire emails sent to 98 hospitals. The frequency of each pathogen was acquired from 32 institutes. Numbers of stool cultures performed ranged from 193 to 14,296 (mean 2,724, SD 3,261) in 2015.

Results: Among 86,744 requested stool specimens, 917 (1.06%, range 0-4.59%, 95% confidence interval 0.63-1.48%) were positive. Salmonella was most prevalent (59.0%), followed by Candida (12.4%), Campylobacter (4.8%), Staphylococcus aureus (4.0%), Vibrio (4.0%), and Pseudomonas aeruginosa (1.75). Yersinia (0.3%) and Shigella (0.2%) were rarely isolated.

Conclusion: As the positive rate of the stool cultures is very low (1.06%), more effort and concern should be provided to enhance the isolation of pathogens. Salmonella was the most prevalent pathogen and Campylobacter and Vibrio were relatively common pathogens causing bacterial gastroenteritis in Korea. (Ann Clin Microbiol 2016;19:105-109)
