Description

technical field

[0001] The present invention relates to short peptides simulating antigenic epitopes of Haemophilus paragallinarum, in particular to a group of short peptides capable of simulating the serotype epitopes of Haemophilus paragallinarum type C, and the use of the group of short peptides in preparing chicken infectious Differential diagnosis of rhinitis and application in vaccine development. technical background

[0002] Haemophilus paragallinarum (Hpg) is a pathogenic bacterium that causes infectious rhinitis in chickens. It can be divided into three serotypes: A, B, and C. Types A and C are common in my country now. Chicken infectious rhinitis is an acute respiratory infectious disease. Its main hazards are the decrease in egg production of laying hens and poor growth of reared chickens. It has been reported in the literature that infectious rhinitis caused by Hpg can reduce egg production by 40%, causing serious economic losses.
