我国十省市空肠/结肠弯曲菌的生物型和血清型分布

本文采用Lior法对我国十省市不同来源的301株空肠/结肠弯曲菌进行了生物学分型与血清学分型研究。研究结果表明弯曲菌的生物型分布无明显地区差异,血清学总分型率为86.71%,共分出41个血清型。人源菌与鸡、猪。鸭源菌的血清型分布关系密切,其最常见的5个血清型中均包括LIO46、45和8。建立了3种新血清型LION-1、N-2和N-3。同一宿主可以同时感染2种血清型的弯曲菌。生物型和血清型分布之间未见特殊联系。

Distribution of Serotypes and Blotypes of Campylobacter JeJuni/coli Strains from Ten Provinces/Cities in China

The Lior's schemes were used for serotyping and biotyping 301 C. jejuni/coli strains isolated from different hosts in ten provinces/cities of China. No difference was found between the serotype distributions of the strains isolated from various areas. Forty-one serotypes were detected. Of the isolates, 86.71% were typable and 3 new serotypes, LIO N-1, N-2 and N-3, were developed. The differences were proved among the serotype distributions of the isolates from different areas. It was shown that one host could be infected by two (or more) strains belonging to different serotypes at the same time. No association between a particular biotype and serotype was observed.
