牛传染性鼻气管炎研究现状

Progress on Infectious Bovine Rhinotracheitis

牛传染性鼻气管炎(IBR)是由牛疱疹病毒1型(BoHV-1)引起牛的一种接触性传染病,表现为上呼吸道感染及气管黏膜炎症、呼吸困难等症状,还可引起生殖道感染、脑膜炎、结膜炎、流产等多种病型。该病呈世界性流行,我国部分地区也有发生。BoHV-1感染造成的免疫抑制,容易使其他病原体侵入引发继发感染,从而导致牛呼吸道疾病综合征(BRDC)的发生,给世界养牛业造成了巨大经济损失。论文围绕IBR病原学、流行病学、诊断、防控等方面阐述了近年来牛传染性鼻气管炎的研究进展,以期为牛传染性鼻气管炎的诊断及防控提供参考。

Infectious bovine rhinotrachealitis is a contagious disease of cattle caused by bovine herpesvirus-1,which manifests as respiratory symptoms,such as upper respiratory tract infections,tracheal mucosal inflammation and dyspnea.It prevails in the worldwide,and also found in some areas in China.BoHV-1 can also cause genital tract infections,meningitis,conjunctival inflammation,abortion and other diseases.BoHV-1 infection can lead to the secondary infection by other pathogens,and bovine respiratory disease complex because of the immunosuppression.The high mortality of IBR has caused great economic losses to the cattle raising industry in the world.This article elaborated the recent research progress of IBR in four aspects including its etiology,epidemiology,diagnosis,prevention and control in order to provide some reference for IBR diagnosis,prevention and control.
