猪副嗜血杆菌病流行病学、诊断及防控

Epidemiology,Diagnosis and Control of Haemophilus Parasuis Disease in Pigs

猪副嗜血杆菌病又被称为关节炎和纤维素性浆膜炎,主要受到猪副嗜血杆菌感染出现的一种传染病。当猪受到感染后,会出现关节炎、心包炎等症状,多发于4月龄猪,青年猪最易受到感染和发病,5周龄仔猪和种猪也易受到感染,但是不明显,患病后出现跛行。该文主要论述猪副嗜血杆菌病流行病学和临床症状,根据解剖变化和诊断等,提出相应的防控措施。

Porcine haemophilus influenzae,also known as arthritis and cellulosic serositis,is an infectious disease caused by haemophilus parasuis.When pigs are infected,they will have arthritis,pericarditis and other symptoms,mostly in 4-monthold pigs,young pigs are most susceptible to infection and disease,5-week-old piglets and breeding pigs are also susceptible to infection,but it is not obvious,after the onset of claudication.This paper mainly discusses the epidemiology and clinical symptoms of porcine haemophilus parasuis,and puts forward the corresponding prevention and control measures according to the anatomical changes and diagnosis.
