Abstract

A bacteriophage typing system for Campylobacter jejuni and Campylobacter coli was developed with phages isolated from poultry feces. Data for phage selection were generated from a set of isolates of C. jejuni and C. coli from humans in Illinois. Selection of 14 phages from the 47 phages available was assisted by determination of the Sneath-Jaccard similarity coefficients and subsequent unweighted pair-group arithmetic averaging cluster analysis. The typing set was reproducible and stable in the 255 isolates from Illinois. Of these isolates, 94.5% were typable, with 46% represented by the four most common phage patterns. In a set of 51 isolates from humans outside of Illinois, 88.1% of the C. jejuni isolates were typable. Phage typing for C. jejuni and C. coli has excellent epidemiologic potential and should serve as a useful adjunct or alternative to serotyping systems in current use.

摘要

利用从家禽粪便中分离出的噬菌体,开发了一种用于空肠弯曲菌和结肠弯曲菌的噬菌体分型系统。噬菌体选择的数据来自伊利诺伊州一组人类空肠弯曲菌和结肠弯曲菌分离株。通过测定斯尼思 - 雅卡尔相似系数并随后进行非加权配对组算术平均聚类分析,从47种可用噬菌体中选择了14种噬菌体。该分型组在来自伊利诺伊州的255株分离株中具有可重复性和稳定性。在这些分离株中,94.5% 可分型,其中46% 由四种最常见的噬菌体模式代表。在一组来自伊利诺伊州以外地区的51株人类分离株中,88.1% 的空肠弯曲菌分离株可分型。空肠弯曲菌和结肠弯曲菌的噬菌体分型具有出色的流行病学潜力,应作为当前使用的血清分型系统的有用辅助手段或替代方法。
