摘要
鸡传染性鼻炎是危害养鸡业的一种重要传染病,发病率高,传播快,虽然病死率低,但如果不及时控制,易继发支原体等其他疾病。近年来,鸡传染性鼻炎又有了新的流行特点,特别是血清B型菌株在国内的出现及流行比例的不断增加,与常用疫苗产品内含有的菌株种的血清型号产生差异,给防控该病带来了新的困难。就鸡传染性鼻炎的流行特点进行概括,并提出综合性防控策略,以便更好地应对该病的流行与防控。
Infectious coryza was an important infectious disease which poses a great threat to chicken industry. This disease is characterized by high incidence and rapid transmission. Although the mortality rate was low, the secondary infections caused by other pathogens such as mycoplasma may emerge when timely control is lacked. In recent years, infectious coryza in chickens starts to exhibit some novel epidemic characteristics, especially the increasing prevalence of serum B-type strains of Haemophilus gallinarum at home. The commonly used vaccine products is failed to provide effective protective immunity against the new prevailing strains, which brings great difficulty to the prevention and control of the disease. Here, we summarize the epidemic characteristics of infectious coryza in chickens and propose comprehensive prevention and control strategies, so as to betterly prevent and control this disease.
