Morphological and morphometrical characterization of gametocytes of Hepatozoon procyonis Richards, 1961 (Protista, Apicomplexa) from a Brazilian wild procionid Nasua nasua and Procyon cancrivorus (Carnivora, Procyonidae)

摘要

The species Hepatozoon procyonis Richards, 1961 was described in Procyon lotor in the USA and then in other reports in the USA, while in Panama H. procyonis has been described in Procyon cancrivorus. The objective of this paper is to report the occurrence of this species in the Brazilian procionids P. cancrivorus and Nasua nausa and to describe the morphology and morphometrics of the gametocytes. The analysis was based on blood smears, stained with Giemsa, which were examined under a photonic microscope. The morphometry was done with an ocular micrometer. It was based on the morphological characteristics and morphometric data on the gametocyte. It can be concluded that the species of the genus Hepatozoon that occurs in Brazilian procionids is the same as that occurring in procionids in Central and North America.
