The genus Salmonella is one of the main pathogens of water and food borne diseases around the world. Salmonella consists of two species, six subspecies, and 2,579 serovars. In this study, we reported the characteristics of Salmonella serotypes isolated from domestic residents and foreign travelers in Korea in 2015. A total of 591 isolates were collected from acute diarrheal patients and environments in regional Institutes of Health and Environment and National Quarantine Stations. Serotypes and antimicrobial susceptibility tests were performed according to Kauffman-White (K-W) methods and CLSI (Clinical and Laboratory Standard Institute) guidelines, respectively. Among the 591 strains of Salmonella, 566 (95.8%) strains were isolated from domestic residents. The most prevalent serotypes were S. Enteritidis (23.4%), Salmonella I 4,[5],12:i:- (12.7%), S. Bareilly (10.7%), S. Typhimurium (8.6%), and S. Montevideo (5.6%). The outbreaks caused by S. Bareilly and Salmonella I 4,[5],12:i:- serotypes occurred in Gyeonggi, Seoul, and Incheon Province. Therefore, S. Bareilly was ranked 3rd grade in 2015 (7th in 2014) and Salmonella I 4,[5],12:i:- was ranked 2nd grade in 2015 (6th in 2014). A total of 247 serotypes were already identified in Korea but nine serotypes were initially reported in 2015. Antimicrobial susceptibility patterns showed similarities with the previous years. The resistance of S. Enteritidis to several antibiotics (AM, SAM, C) decreased significantly in 2015 (as compared with 2014) but the resistance of S. Typhimurium to several antibiotics (CF, C) increased. The possibility or risk of infection increased and the infectious disease pattern has changed, due to increase in population migration and distributions. Consequently, it is necessary to conduct a thorough epidemiological survey according to the characteristic changes among patients.
