Cowdria ruminantium was isolated from a natural infection of heartwater in a captive sitatunga (Tragelaphus spekei) which died after a short illness in Jos Zoo, Nigeria. The isolate killed laboratory mice in a shorter period of time than did isolates of C. ruminantium recovered from natural cases in cattle. This is the first confirmed case of heartwater in a captive wild ruminant in Nigeria, where the disease is endemic.
从尼日利亚乔斯动物园一头圈养的大林羚（Tragelaphus spekei）自然感染心水病后分离出反刍兽考德里氏体。这头大林羚患病不久后死亡。该分离株致使实验小鼠死亡的时间比从牛的自然病例中分离出的反刍兽考德里氏体分离株更短。这是尼日利亚圈养野生反刍动物中首例确诊的心水病病例，该病在该国为地方病。
