초록
The clinical specimens used in this study were collected during the period from March 4, to December 30, 1983, from children's hospitals in Seoul area. They came from clinically apparent cases of diarrheal disease in hospitals. Many specimens were taken from rectal Swabs. During this period, 2166 stool cultures were streaked onto MacConkey plate and were them deposited in selenite broth. Colonies resembling pathogens on MacConkey medium were picked to KIA, Urea agar, malonate broth, ONPG broth, SIM. Reaction on those media cultures were identified biochemically with using API 20E test kit and confirmed serologically with commercially avabile Salmonella antisera(Difco) or Shigella antisera(Denka, Japan). The sensitivity of Salmonella and Shigella tested to ampicillin cephalosporin, chloramphenicol, colistin, gentamicin, tetracycline, streptomycin, nalidixic acid, neomycin, polymyxin B was performed by means of disc diffusion method recommended by Bauer-Kirby, using the discs prepared in BBL Laboratory. 1. There were 34 (1.6%) isolations of Salmonella cultures and 52(2.4%) isolations of Shigella from the 2,116 specimens. Only 53%of Salmonella were isolated by direct streaking on MacConkey plating media, by contrast, 80% of the Shigella were isolated directly. 2. Shigella flexneri types comprised 56% of the Shigellae isolate from 52 Shigellae identified 24% of Salmonella enteritidis ser typhimurium were identified. 3. Concerning to Salmonella and Shigella occurance according to month and sex, They shows relatively higher for the male than in case of female, and 2-3 age were shown the highest group. 4. October is the month with highest incidences. 5. In the sensitivity patterns of Shigellae, most of them were appeared to be resistant ampicillin, streptomycin, tetracycline, in case of Salmonella, 15% of them were resistant to chloramphenicol.
