Abstract

The serotypes of 101 faecal bovine necrotoxigenic Escherichia coli (NTEC) producing the cytotoxic necrotizing factor type 2 (CNF2) were determined. Although, NTEC producing CNF2 belonged to 48 different O:K:H serotypes, only eleven of them accounted for 54% of strains. The most common serotypes in order of frequency were: O123:K-:H16, O3:K-:H21, O88:K-:H8, O15:K14:H21, O1:K-:H12, O1:K1:H46, O2:K1:H5, O55:H21, O88:K?:H25, O117:K?:H21 and O123:K-:H-. The serotypes of CNF2 NTEC were different from those found in NTEC producing CNF1 and in enterotoxigenic, verotoxigenic, enteropathogenic, enteroinvasive and enteroadherent E. coli strains that cause infections in humans and animals.

摘要

对101株产细胞毒素坏死因子2（CNF2）的粪便牛源坏死毒素大肠杆菌（NTEC）的血清型进行了测定。尽管产CNF2的NTEC属于48种不同的O:K:H血清型，但其中只有11种血清型占菌株总数的54%。按频率排序最常见的血清型依次为：O123:K-:H16、O3:K-:H21、O88:K-:H8、O15:K14:H21、O1:K-:H12、O1:K1:H46、O2:K1:H5、O55:H21、O88:K?:H25、O117:K?:H21和O123:K-:H-。产CNF2的NTEC血清型与产CNF1的NTEC以及在人和动物中引起感染的产肠毒素、产志贺毒素、肠致病性、肠侵袭性和肠黏附性大肠杆菌菌株中发现的血清型不同。
