Establishment of a Multilocus Sequence Typing Scheme for the Characterization of .

Infectious coryza is an acute respiratory infection caused by , which is widely distributed throughout the world. However, there is no effective molecular typing scheme to obtain basic knowledge about the population structure. This study aimed to develop a multilocus sequence typing (MLST) scheme for that allows for the worldwide comparison of sequence data.

Basic Characterization of Natural Transformation in Avibacterium paragallinarum.

Avibacterium paragallinarum is the pathogen involved in infectious coryza (IC), an acute infectious upper respiratory disease in chickens. The prevalence of IC has increased in China in recent years. There is a lack of reliable and effective procedures for gene manipulation, which has limited the research on the bacterial genetics and pathogenesis of A.

The Protective Efficacy of an Inactivated Vaccine against Field Isolates.

Infectious coryza (IC) is an acute respiratory disease caused by Avibacterium paragallinarum (Av. paragallinarum). In recent years, there have been frequent outbreaks of IC in chickens vaccinated with an inactivated vaccine, causing huge losses to the poultry industry.
