Serotyping and Antimicrobial Susceptibility of Salmonella spp.: Nationwide Multicenter Study in Korea.

Serotyping and Antimicrobial Susceptibility of Salmonella spp.: Nationwide Multicenter Study in Korea. Jpn J Infect Dis. 2013;66(4):284-9 Authors: Lee JY, Kim JA, Jeong HS, Shin JH, Chang CL, Jeong J, Cho JH, Kim MN, Kim S, Kim YR, Lee CH, Lee K, Lee MA, Lee WG, Shin JH, Lee JN Abstract The study aimed to investigate the prevalence of various serotypes and extended-spectrum β-lactamase-producing features of Salmonella strains and to determine the antimicrobial susceptibility of 256 Salmonella strains other than Salmonella serotype Typhi, which were isolated at 12 university hospitals in Korea. We identified 46 serotypes of Salmonella spp. Serogroup D was the most common (39.5%), followed by B (32.4%), C (22.7%), E (2.7%), A (2.3%), and G (0.4%). The three most common Salmonella serotypes were Enteritidis (36.3%), Typhimurium (16.8%), and Infantis (7.8%). Six strains that belonged to serotype Paratyphi A and nine that belonged to serotype Paratyphi B were also detected. The 256 Salmonella strains had a 38.7% rate of resistance to ampicillin, 23.0% to chloramphenicol, 8.2% to cefotaxime, 8.6% to ceftriaxone, and 6.3% to trimethoprim-sulfamethoxazole. The antimicrobial resistance rates of Salmonella serogroups B and D were higher than those of the other serogroups. Seven isolates carried blaCTX-M: four CTX-M-15, two CTX-M-14, and one CTX-M-3.
