一、保虫宿主和传播内脏利什曼病感染宿主的范围较其它类型利什曼病单纯。野犬、家犬和人本身以及啮齿动物都可成为宿主和感染的保虫宿主。因此,最好是在生物学基础上来改虑黑热病,可把它分成以犬为保虫宿主的内脏利什曼病,以人为保虫宿主的内脏利什曼病和可能以啮齿动物为保虫宿主的非洲黑热病。 First, the host of insecticide-borne and disseminated visceral leishmaniasis host range than other types of leishmaniasis simple. Wild dogs, domestic dogs and humans themselves, as well as rodents, can be hosts for host and infection hosts. Therefore, it is best to think of kala-azar on the basis of biology. It can be divided into visceral leishmaniasis that takes dogs as host for preserving insects, visceral leishmaniasis for human-preserving hosts and probable rodent pests Host kala-azar.
