Seroprevalence, clinical findings, and lesions of contagious caprine pleuropneumonia (CCPP) in Beetal goats were recorded during an outbreak. The overall seroprevalence of CCPP was 32.50%. Confirmation of Mycoplasma mycoides in serum was carried out using counter immunoelectrophoresis (CIE) technique. The highest CIE-positive cases were recorded in the older goats (51.72%) as compared to young ones. Nasal swabs collected from 39 goats showing respiratory signs were found positive for M. mycoides. The most consistent clinical findings were mild to severe cough, purulent nasal secretion, emaciation, dyspnea, increased respiration rate, and pyrexia. Mortality due to CCPP was 9.17%. Consolidation of lungs exhibited the highest frequency (100%), followed by alveolar exudation (90.90%) and pleural adhesion (72.72%). Among the microscopic lesions, septal peribronchiolar fibrosis exhibited the highest frequency (81.81%), followed by fibrinous pleuritis (63.63%) and peribronchiolar cuffing of mononuclear cells (54.54%) in lungs. From these results, it was concluded that CCPP under subtropical conditions has high prevalence in Beetal goats and leads to significant mortality.
在一次疫情爆发期间,记录了比塔尔山羊传染性山羊胸膜肺炎(CCPP)的血清阳性率、临床症状和病变情况。CCPP的总体血清阳性率为32.50%。采用对流免疫电泳(CIE)技术对血清中的丝状支原体进行确诊。与年轻山羊相比,老年山羊的CIE阳性病例记录最高(51.72%)。从39只出现呼吸道症状的山羊采集的鼻拭子中发现丝状支原体呈阳性。最常见的临床症状是轻度至重度咳嗽、脓性鼻分泌物、消瘦、呼吸困难、呼吸频率增加和发热。CCPP导致的死亡率为9.17%。肺部实变的发生率最高(100%),其次是肺泡渗出(90.90%)和胸膜粘连(72.72%)。在微观病变中,肺间隔支气管周围纤维化的发生率最高(81.81%),其次是纤维蛋白性胸膜炎(63.63%)和支气管周围单核细胞套袖状浸润(54.54%)。从这些结果可以得出结论,在亚热带条件下,CCPP在比塔尔山羊中具有高流行率,并导致显著的死亡率。
