Blood samples were taken from 39 black rhinoceros (Diceros bicornis), usually soon after they were captured. The blood was examined microscopically for trypanosomes, and most samples were tested for trypanosome serum antibodies and inoculated into small laboratory animals. Serum antibodies were found in most animals and trypanosomes identified as Trypanosoma brucei were found in 7 of 39 (18%) of the rhinoceros. Berenil (diminazene aceturate) did not effect complete elimination of trypanosomes. In spite of treatment, one rhinoceros died of trypanosomiasis.
血液样本取自39头黑犀（双角犀属），通常在它们被捕后不久采集。对血液进行显微镜检查以寻找锥虫，大多数样本检测了锥虫血清抗体，并接种到小型实验动物体内。在大多数动物体内发现了血清抗体，在39头犀牛中的7头（18%）体内发现了被鉴定为布氏锥虫的锥虫。贝尼尔（乙酰甘氨酸二脒那嗪）未能完全清除锥虫。尽管进行了治疗，仍有一头犀牛死于锥虫病。
