猪副嗜血杆菌病发病特点表现为多发性浆膜炎、关节炎和脑膜炎。疾病主要发生于保育猪阶段,目前给我国猪群带来很大威胁,随着猪繁殖与呼吸综合征的流行,猪副嗜血杆菌病给猪群造成的损失比以往更为严重,而爆发性的猪副嗜血杆菌病也比以往更为普遍。由于药物滥用导致猪副嗜血杆菌的耐药性越来越严重,当务之急是如何有效控制本病,文章就当今副猪嗜血杆菌病的防治提出有效的方法。 相似文献

<正>猪副嗜血杆菌病是由猪副嗜血杆菌引起猪的多发性浆膜炎和关节炎的细菌性传染病,主要引起肺的浆膜和心包及腹腔浆膜和四肢关节浆膜的纤维素性炎为特征的呼吸到综合症。近年来,副猪嗜血杆菌、猪链球菌、猪放线杆菌已成为了养猪业的重要病原菌,尤其在高健康猪场中更是如此。副猪嗜血杆菌和猪链球菌成了最为常见并造成严重经济损失的传染性病原体。 相似文献

Eight hundred and fifty-four piglets which died or were euthanized due to pneumonia or rhinitis atrophicans, were investigated during the period of 1986-1990. Of the animals, 569 showed bronchopneumonia, 218 had pleuritis, pericarditis and peritonitis, 165 had rhinitis atrophicans, 58 pleuropneumonia, and 9 animals had fibrinous pneumonia. Pasteurella multocida, Haemophilus parasuis, Bordetella bronchiseptica, Actinobacillus pleuropneumoniae and Pasteurella haemolytica were isolated in 59.1%, 29.5%, 27.8%, 3.7%, and 2.3% cases of bronchopneumonia respectively. Samples from pigs with pleuritis or rhinitis atrophicans showed Pasteurella multocida in 63.8 and 68.5%, Bordetella bronchiseptica in 28.4 and 39.4%, streptococci in 28.9 and 3.9%, Haemophilus parasuis in 25.2% and 20.6%, Actinobacillus pleuropneumoniae in 5.1 and 5.5%, and Pasteurella haemolytica in 3.2 and 3.0%, respectively Actinobacillus pleuropneumoniae was found in 51 of 58 cases of pleuropneumonia and in 5 of 9 cases of fibrinous pneumonia; 55.6% and 44.4% respectively of those forms of pneumonia were positive for Pasteurella multocida. In the agar diffusion test, 36.8-82.6% of bacterial isolates showed resistance to streptomycin, 7.7-45.5% to sulfamethoxazole-trimethoprim, 5.7-44.6% to tetracycline, 0.2-32.8% to ampicillin, 0.0-16.3% to lincospectin, 2.0-81.2% to furazolidone, 0.4-4.5% to chloramphenicol, 1.3-78.1% to penicillin and 0-0.3% to enrofloxacin. 相似文献

2006年3月，开阳县某养猪场引进的商品猪发生一种死亡率为45％的疫病，经流行病学调查、临床症状与病理剖解观察、猪瘟荧光抗体试验和细菌分离培养与鉴定，确诊本次疫病系猪瘟与副伤寒混合感染所致。 相似文献

At present, African swine fever (ASF) persists as an enzootic infection both on the African continent and in Europe (Portugal, Spain, and Sardinia). The recent outbreaks of ASF in Belgium and in the Netherlands have again demonstrated the threat of this disease to the swine population in Germany. The main reasons for this threat are the great tenacity of this virus and its stability in meat and meat products together with an immense tourism into these enzootic areas. Epizootiological peculiarities, such as virus replication in ticks and inapparent infections in wild boars are the reason why eradication of the disease has failed so far, especially when pigs are allowed to roam the countryside. 相似文献
