[Epidemiological analysis of Salmonella serovar enteritidis isolated from patients with sporadic cases of diarrhea in 1989].
A total of 184 strains of S. Enteritidis isolated from patients with sporadic cases of diarrhea during the period from April 1985 to March 1991 in Yamanashi Prefecture, were examined for their drug susceptibility, phage typing and plasmid profile. The results can be summarized as follows: 1) In 1989, cases of sporadic diarrhea due to S. Enteritidis has drastically increased twenty-eight-fold from 4 to 112 cases. 2) The most predominant ages of S. Enteritidis isolates were that of 2 years age. 3) The predominant phage type (PT), accounting for almost 71% of the strains isolated, was PT 34 in 1989. 4) Eighty-two (73.2%) out of 112 strains of S. Enteritidis were resistant to SM single in 1989. In 1990, SM single resistant strains were 49 (90.7%) out of 54 strains of S. Enteritidis. 5) The predominant plasmid profile of S. Enteritidis isolates were 60, 55 Kbp plasmids. 6) In 1989, the characteristic of S. Enteritidis isolated from the cases of sporadic diarrhea were resistant to SM single, identified as belonging to PT 34 or PT 4. Almost S. Enteritidis strains of PT 34 carrying 60, 55 Kbp plasmids and many strains of PT 4 S. Enteritidis possessed only 60 Kbp plasmid.
