Isolation of Sh. Flexneri lc from Dysentery Cases in Ujiie, Tochigi Prefecture

Abstract

Twenty two strains of Shigella, 2 of Salmonella, 1 of each of E. coll. 0-26, 0-55 and 0-75, and 6 of citrobacter (Bethesda group) were isolated from the patients suffering from diarrhea in a village, Ujiie, Tochigi Prefecture during the period from July to October, 1956.
Of the 22 strains of Shigella isolated, four were found to be identical with the Sh. flexneri lc (1: 7 (8, 9)) reported by Ohashi et al. Among the four patients, from whom the Sh. flexneri lc was isolated, two demonstrated simple acute colitis, while dysenteric symptoms became manifest in the other two. Furthermore, from one of the cases, Sh. flexneri 3a and E. coli 0-75 were also isolated at the same time.
Antibiotic sensitivity tests revealed that the growth of the strains in question was inhibited by streptomycin, oxy-tetracline and chlor-tetracycline at a concentration of 0.1μg/cc and by chloramphenicol at 0.5μT/cc.
