Insight into the Specific Virulence Related Genes and Toxin-Antitoxin Virulent Pathogenicity Islands in Swine Streptococcosis Pathogen Streptococcus equi ssp.zooepidemicus Strain ATCC35246

摘要

Background:S.zooepidemicu.s is the ancestor of Streptococcus equi ssp.equi(S.equi)and they expresses many of the same proteins and virulence factors,but unlike the S.equi,which is host-restricted and only infects horse.S.zooepidemicus has no host preference.This hacterium is primarily an opportunistic pathogen infecting a wide variety of animal species,including important domestic species,so it is a pathogen of veterinary concern.In China,it is an important pathogen of swine streptococcosis,causing septicemia,meningitis,endocarditis and arthritis.resulting in significant economic losses.
