cyclozoonosis

The transmission cycle of the cyclozoonoses, of which tapeworm infections are an example, requires at least two different vertebrate species. Both vertebrate and invertebrate animals are required as intermediate hosts in the transmission to humans of metazoonoses; arboviral and trypanosomal diseases are good examples of metazoonoses. The cycles of saprozoonoses…

Cyclozoonoses, such as echinococcosis, require more than one vertebrate host for development. Metazoonoses require both a vertebrate host and an invertebrate host; an example is trypanosomiasis. Zoonotic diseases that require a vertebrate host and another type of environmental reservoir (e.g., food or soil) are known…
