Y. Miyao et al., PREVALENCE OF VEROTOXIN-PRODUCING ESCHERICHIA-COLI HARBORED IN THE INTESTINE OF CATTLE IN JAPAN, Veterinary microbiology, 61(1-2), 1998, pp. 137-143
The production of verotoxin was examined in 2152 Escherichia coil isol
ates from 387 cattle in Japan from 1992 to 1994. The toxin was detecte
d in 263 isolates from 94 cattle (detection rate: 24.3%). Verotoxin-pr
oducing E. coli (VTEC) was isolated from the cattle in 15 out of 17 pr
efectures, and the strains were divided into 33 serotypes. E. coli 015
7.H7 was isolated from 7 out of 387 cattle (detection rate: 1.8%) in f
our prefectures. These results suggest that VTEC is widely distributed
in Japan and include a wide variety of serotypes. (C) 1998 Elsevier S
