摘要
为了解重庆市渝东地区规模猪场副猪嗜血杆菌感染程度及药敏谱,采用流行病学调查及正向血凝试验对梁平县、万州区、云阳县30头及以上母猪规模的31个规模养猪场进行副猪嗜血杆菌血清学检测及实验室分离鉴定与药敏试验。结果表明,重庆市渝东地区养猪业规模化程度和养殖水平总体偏低;副猪嗜血杆菌血清学阳性率平均为19.2%;万州区、梁平县及云阳县三区县规模猪场副猪嗜血杆菌阳性率分别为22.22%、20.84%、16.67%;该地区规模猪场之间、三区县间及各区县内各规模猪场间副猪嗜血杆菌阳性率差异均不显著(P>0.05)。分离的3株疑似副猪嗜血杆菌菌株对头孢类、粘杆菌素类高度敏感;对四环素类、喹诺酮类、青霉素类药品明显耐药。规模猪场用药习惯、种猪来源地及保健方案直接影响重庆渝东地区副猪嗜血杆菌的耐药谱。
In order to study the infected level and the sensitivity spectrum of to Haemophilus Parasuis to drugs in the scale swine farms in parts of east Chong Qing,descriptive epidemiological investigation and positive hemagglutination kit for haemophilus parasuis were employed to isolate and identify the isolated Haemophilus parasuis and their drug sensitivity in 31 pig farms with 30 and more sows in the three counties of Wanzhou,Liangpin and Yu Yang in the east of Chongqing.The results showed that the average positive rate is 19.2%. The average positive rates of haemophilus parasuis in the three districts and counties is 22.22%,20.84%,and 16.67%,respectively.The differences in the positive rates of haemophilus parasuis among the medium and large pig farms of the three counties,in the three districts and counties are insignificant（P〉0.05）.The three isolated strains of haemophilus parasuis were more sensitive to cephalosporin drugs and Coli drugs.The strains isolated in this experiment have obviously drug resistance（100%）to Tetracycline drugs,Quinolone drugs,and Penicillin. The study showed that the haemophilus parasuis infection rate of the pig farm in the parts of east of Congqing was low.
