[Serovars and drug susceptibility of Salmonella isolated in humans from 1987-1993 in Aichi prefecture].
Drug susceptibility and serovars for a total of 1,110 strains of Salmonella isolated from humans during a period from 1987-1993 in Aichi prefecture were studied. The isolates consists of 1,022 strains from healthy individuals and patients with sporadic diarrhea, 36 imported strains from overseas travellers, and 52 strains from patients involved in 7 food poisoning incidents. The strains of the first group were serologically classified into 93 serovars. The predominant serovars isolated were S. Enteritidis, S. Litchfield, S. Hadar, S. Typhimurium and S. Infantis. In drug susceptibility tests using 8 drugs, the frequency of drug resistance and number of patterns of resistant isolates were 46% and 33 patterns, respectively. There were different resistant rates and characteristic resistance patterns in each serovar of the isolates. Some of the resistance patterns of isolates derived from food poisonings were rare during the year of occurrence. Thus, it seems that surveillance of Salmonella may provide valuable fundamental epidemiological data.
