Comparative genomics of Helicobacter pullorum from different countries.

ABSTRACT:

Background

Helicobacter pullorum commonly colonized in the gastrointestinal tract of poultry and caused gastroenteritis. This bacterium could be transmitted to humans through contaminated food and caused colitis and hepatitis. Currently, the genetic characteristics of the H. pullorum were not recognized enough. In this study, the genomes of 23 H. pullorum strains from different counties were comparatively analyzed. Among them, H. pullorum 2013BJHL was the first isolated and reported in China.

Results

The genomes of the studied strains were estimated to vary from 1.55 to 2.03 Mb, with a GC content of ~ 34%. 4064 pan genes and 1267 core genes were obtained from the core-pan genome analysis using the Roary pipeline. Core genome SNPs (cg-SNPs) were obtained using Snippy4 softwar
