Abstract

Mycoplasma capricolum subsp capripneumoniae (Mccp) produced no overt disease in Red Bororo calves inoculated intratracheally with 10ml of 1x109 CFU/ml of the organism. However when Red Bororo calves were immunosuppressed with Trypanosoma congolense (Tc) and subsequently challenged intratracheally with Mccp, typical lesions of CBPP were produced. The mean PCV value (mPCV), of each of the four Tc-infected RB calves (20.7±2.4%, 23.5±2.5%, 23.3±3.9% and 22.3±2.4%) was significantly (P M. capricolum subspecies capripneumoniae.

牛卡布利肺炎支原体亚种致病性的研究

在气管内接种10ml 1 × 109 CFU/ml的山羊支原体卡普肺炎亚支原体(Mccp)后，红波罗罗犊牛无明显病变。然而，当红波罗罗犊牛被刚果锥虫(Tc)免疫抑制，随后气管内被mcp攻击时，会产生典型的CBPP病变。4只感染tc的RB犊牛的PCV平均值(20.7±2.4%，23.5±2.5%，23.3±3.9%和22.3±2.4%)均显著高于山羊分枝杆菌卡普肺炎亚种。关键词:小牛，刚果锥虫，免疫抑制，卡普肺炎支原体，气管内接种，尼日利亚太。兽医。Vol.22:(1) 33-40 (2004)
