In human cell they exist as small, spherical and unflagellated amastigote form; while they are elongated with flagellum ...
The black rat is a reservoir host for bubonic plague. The rat fleas that infest the rats are vectors for the disease. In biology and medicine, a host is a larger organism that harbours a smaller organism; [1] whether a parasitic, a mutualistic, or a commensalist guest .

[6] [7] Manson proposed the snail as an intermediate host and various Japanese scientists detailed the whole life cycle in the snail between 1916 and 1922. [8] The species name P. westermani was named after Pieter Westerman (1859–1925), a zookeeper who noted the trematode in a Bengal tiger in an Amsterdam Zoo[Artis].

Fasciola hepatica occurs in the liver and bile ducts of a definitive host and its lifecycle is indirect. Definitive hosts of the fluke are cattle, sheep and goats as well as water buffalo. [6] Wild ruminants, such as African buffalo, [7] and other mammals, including humans, can act as definitive hosts as well. [8]
