Abstract

Clinico-pathological profiles were studied in adult and young Friesian cattle naturally infected with Theileria annulata in the Qassim Region, Saudi Arabia. Sixty-two clinical cases of T. annulata infection in adult and young Friesian cattle were diagnosed during the period from August 1999 to July 2000. Symptoms observed were marked fever, swelling of superficial lymph nodes, inappetance, tachycardia, dyspnoea and weakness. The most prominent gross pathological features were jaundice, petechial and ecchymotic haemorrhages involving mucosal and serosal surfaces of many organs as well as body fat. A number of young and adult Friesian cattle undergoing lethal T. annulata infection developed lymphoma-like lesions in a manner similar to that of T. parva. The main histological findings were necrosis and severe lymphocytic infiltration. The spleen, lymph nodes and Peyer's patches were devoid of typical lymph nodules.

摘要

在沙特阿拉伯卡西姆地区，对自然感染环形泰勒虫的成年和幼年弗里斯兰牛的临床病理特征进行了研究。在1999年8月至2000年7月期间，诊断出62例成年和幼年弗里斯兰牛感染环形泰勒虫的临床病例。观察到的症状有高热、浅表淋巴结肿大、食欲不振、心动过速、呼吸困难和虚弱。最显著的大体病理特征是黄疸，许多器官以及体脂的黏膜和浆膜表面出现瘀点和瘀斑出血。一些遭受致命环形泰勒虫感染的幼年和成年弗里斯兰牛以类似于小泰勒虫的方式出现了淋巴瘤样病变。主要组织学发现为坏死和严重的淋巴细胞浸润。脾脏、淋巴结和派伊尔氏淋巴集结均无典型的淋巴小结。
