摘要:猪传染性胸膜肺炎是严重危害现代养猪业的一种呼吸道传染病,广泛流行于全国各地。在内蒙古包头市一养猪场分离培养出1株猪传染性胸膜肺炎放线杆菌,并通过治疗试验发现氟苯尼考和强力霉素对该菌株治疗效果好。对猪传染性胸膜肺炎的病因进行了分析,并提出了控制疫情的有效措施。

Abstract: Porcine contagious pleuropneumonia is a respiratory infectious disease which is harmful to the modern pig industry and widely spread all over China. In this study, one strain of Actinobacillus pleuropneumoniae was isolated and cultured from a hog farm in Baotou inInner Mongolia. Through treatment trial, it was found that the florfenicol and doxycycline had positive effects on the disease. Meantime, based on the cause analysis of infectious Pleuropneumonia, some effective measures were put forward to control the epidemic.

豬传染性胸膜肺炎是由胸膜肺炎放线杆菌(Actinobacillus pleuropneumoniae,APP)所引起的高度传染性疾病,又称为猪接触性传染性胸膜肺炎,是以急性出血性、纤维素性胸膜炎和慢性纤维性、坏死性肺炎为主要特征的一种呼吸道传染病。猪传染性胸膜肺炎广泛流行于全国各地,给集约化养猪业造成巨大的经济损失,尤其是近几年来该病的流行呈上升趋势,是被世界公认的危害现代养猪业的严重细菌性呼吸道疾病之一。该病急性型呈现高死亡率,慢性型常能耐过,不同年龄的猪均易感,但以4~5月龄的猪死亡较多[1]。

引起猪传染性胸膜肺炎的病原体是胸膜肺炎放线杆菌(APP),是小到中等大小的球杆状到杆状、革兰氏阴性、有荚膜、多形性球状短杆菌,老龄培养物偶可见到丝状,在牛血清琼脂培养基生长良好,呈圆形、隆起、表面光滑、边缘整齐的灰白色半透明小菌落。在血液琼脂平板上可呈不透明扁平的圆菌落,出现β溶血,在β毒素源性金黄色葡萄球菌周围产生更宽的溶血带和“卫星”现象。……
