An outbreak of malignant catarrhal fever (MCF), a fatal viral disease in indigenous Tanzanian shorthorn zebu in Ngorongoro district of Tanzania during the period of June 2004 has been described. The disease was diagnosed by clinical, post mortem findings and the virus was identified using molecular characterization study. The history and clinical features included pyrexia, cornel opacity, nasal discharges, multifocal buccal ulceration of varying size and general unthrifty. Pathological features showed that abomasum and intestine contents were blood tinged and their walls were congested and hyperemic with scattered hemorrhagic patches. Furthermore greenish-black longitudinal stripes in the caecum and ileo-caecal junction that disappeared upon opening of the intestine were a distinct feature. It has been concluded that as the wildebeest have a wide distribution throughout Tanzania, it is likely that MCF occurs in many parts of the country and therefore continuation of surveillance system seems necessary.
本文描述了2004年6月期间，在坦桑尼亚恩戈罗恩戈罗区本土的坦桑尼亚短角瘤牛中爆发的恶性卡他热（MCF），这是一种致命的病毒性疾病。通过临床症状、尸检结果对该疾病进行了诊断，并利用分子特征研究鉴定出了病毒。病史和临床特征包括发热、角膜混浊、鼻分泌物、大小不一的多灶性颊部溃疡以及整体消瘦。病理特征显示，皱胃和肠内容物带有血丝，其壁充血、发红，有散在的出血斑。此外，盲肠和回盲交界处有绿黑色的纵向条纹，在打开肠道后消失，这是一个明显的特征。得出的结论是，由于角马在坦桑尼亚各地分布广泛，MCF很可能在该国许多地区发生，因此似乎有必要继续开展监测系统。
