초록

A total of 114 Salmonella spp. (17.90%) were isolated from 637 fecal swab samples collected in October 2005 and they were from 25 (78.13%) of 32 farms investigated nation-widely in Korea. Salmonella spp. from age group of 30-, 60-, 90-, 120-day olds were 17.61%, 16.98%, 15.72%, and 21.25%, respectively. Nine serovars of Salmonella spp. were identified. The predominant serovars of isolates were S. Typhimurium (including var Copenhagen), S. Agona, S. Derby, and S. Heidelberg by turns. Almost isolates belonged to serogroup B (69.30%). All isolates were resistant to penicillin G and oxytetracycline, and this was considered due to be used as feed additive through the most of pig farms for decades. And also, frequent resistance observed for ampicillin, sulfamethoxazole-trimethoprim, and lincomycin-spectinomycin, which are commonly used in veterinary medicine for decades, indicates an urgent need to utilize these antimicrobials more prudently if their benefits are to be preserved.
