Aspecto morfológico e histopatológico de parasitos da classe myxozoa e filo apicomplexa em Cichla monoculus (Spix & Agassis, oriundos do município de Pracuúba- Amapá, Brasil.

Abstract

The Brazilian Amazon is privileged to have the largest freshwater basin in the world with a diversity of fish species. The state of Amapá has five sectors for fishing activities in the region: the maritime plain on the north coast, the urban and port area located in Macapá and Santana, the upper estuary region that begins at the mouth of the Matapi River up to the border with the state of Pará and the lakes region where the municipality of Pracuúba is located. The Tucunaré (Cichla sp.) is a commercially important Amazonian fish, and the Cichla monoculus is a species with a wide geographical distribution that is widely consumed by the riverside population. Fish are vulnerable to different parasites, including myxozoans and coccids from the Apicomplexa phylum. The aim of this study was to investigate eukaryotic microparasites of the Class Myxozoa and Phylum Apicomplexa in Cichla monoculus from the municipality of PracuúbaAmapá, Brazil. This research resulted in two scientific articles: the first on the morphology and histopathological changes caused by the Apicomplexa parasite of the genus Calyptospora infecting the liver of Cichla monoculus and the second on the morphological aspects and infection by myxozoans in Cichla monoculus.
