在肯尼亚证实有4种利什曼原虫对人致病,引起皮肤利什曼病的有埃塞俄比亚利什曼原虫、大型利什曼原虫和热带利什曼原虫,内脏利什曼病或黑热病则由杜氏利什曼原虫引起。内脏利什曼病在农村有活动性疫点,最近又有一新疫点发生。在研究利什曼病皮肤损害的诊断时,发现一病人的皮肤损害是由杜氏利什曼原虫所引起,而通常这种原虫常罹及内脏器官。本文报导此病例的临床表现,用同工酶和DNA对原虫的鉴定结果。 Four leishmaniasis confirmed to be human in Kenya, Leishmania ethicis, Leishmania major and Leishmania leishmanii, visceral leishmaniasis or kala-azar caused by leishmaniasis in Kenya Leishmania donovani cause. Visceral leishmaniasis is an active epidemic in rural areas and a new outbreak has recently occurred. In studying the diagnosis of leishmaniasis skin lesions, it was found that a patient’s skin lesions are caused by Leishmania donovani, and often the protozoa often attack internal organs. This article reports the clinical manifestations of this case, using isozymes and DNA on protozoa identification results.
