副鸡禽杆菌毒力因子研究进展
Research Progress on the Virulence Factors of Avibacterium paragallinarum
摘要
Abstract
Avibacterium para gallinarum(Apg)is the pathogen of infectious coryza in chickens.It induces symptoms such as nasal cavity mucus secretion,sneezing,infraorbital sinus swelling,facial edema,and conjunctivitis.These clinical manifestations lead to stunted growth and a sig-nificant decrease in egg production,posing a threat to poultry farming.The pathogenicity of Apg is influenced by various factors,including cell wall structural components like capsule and lipopo-lysaccharide,as well as functional proteins secreted by the cell such as hemagglutinin and metal-loproteinases.This paper provides a review of the research progress on the virulence factors of Apg,focusing on the biofilm system,secretory system,and bacterial iron capture system.The aim is to offer a theoretical reference for the scientific prevention and treatment of infectious cory-za in chickens.关键词
