We analysed the pattern of isolates and the antibiotic susceptibility of 611 salmonella strains in Kyung Hee University Hospital from 1980 to 1986 and the clinical characteristics of 22 salmonella enterocolitis caused by S. typhimurium in 1986.
The results are as follows;
1) The isolation pattern of salmonellae(1980~1986) showed that the incidence of group A salmonella and S. typhi decreased and that of group D increased.
2) The isolation rate of group B salmonella was markedly increased in 1986 compared with that in 1980~1985. Group B salmonella infections occur with greatest frequency from June through August, 1986.
3) The isolation rate of salmonella group B and group C from stool were 81% and 59% respecitively. However, the isolation rate of salmonella in general from blood(63%) was higher than that from stool (29%).
4) In antibiotic sensitivity test of 36 isolates of group B salmonella, 13 of 13 isolates from 1980 to 1985 showed no antibiotic resistance. But 18 of 23(78%) isolates in 1986 showed the resistance to chloramphenicol, ampicillin and carbenicillin.
5) Group B salmonella isolated in 1986 was sensitive to aminoglycoside, cephalothin, pipemidic acid and trimethoprim-sulfame thoxazole.
6) The serovar of group B salmonellae isolated in 1986 was salmenella typhimurium.
7) The main clinical manifestations of S. typhimurium enterocolitis were diarrhea and fever.
