[Serovars and drug susceptibility of Salmonella isolated from patients with sporadic diarrhea in Yamanashi Prefecture during the last decade (1985-1994)].
A total of 1242 strains of Salmonella isolated from patients with sporadic diarrhea during the period from April 1985 to December 1994 in Yamanashi Prefecture, were tested for their serovars and drug susceptibility. The results can be summerized as follows: 1) The isolates were serologically classified into 54 different serovars. The predominant serovars were S. Enteritidis (39.6%), S. Typhimurium (16.6%), S. Oranienburg (4.8%), S. Hadar (4.6%), S. Litchfield (4.4%). 2) Serovars of S. Stanleyville, S. Hartford, S. Rissen, S. Chincol, S. Gaminara, S. Poona and S. Hvittingfoss were isolated from human sources for the first time in Yamanashi Prefecture. 3) Yearly frequency of isolates was 19.2% in 1989, 15.5% in 1994, 11.8% in 1993. 4) Monthly frequency of isolates was 21.2% in August, 17.1% in September, 12.0% in October, 11.2% in July. 5) The predominant age of isolates were 2 years of age (99 strains: 8%), 1 year of age (92 strains: 7.5%), 4 years of age (68 strains: 5.5%), 3 years of age (64 strains: 5.2%) and under 1 year of age (62 strains: 5.0%). 6) The rate of isolates from males was higher than females (Male: 58.0%, Female: 42,0%). 7) The frequency of resistant isolates was 62.5% in the period. The most predominant resistance pattern was SM single resistance because of the increase of S. Enteritidis. 8) The number of resistant strains of S. Enteritidis was 424 out of 492 strains (86.2%).
