SUMMARY:

The Amazon covers an area of more than seven million square kilometers and stands out for its
high level of biodiversity. This biome is home to the largest and most abundant river on the
planet, the Amazon, with an estimated three thousand species of fish, ranging from basal to
endemic species. Amapá is located in the eastern Amazon and is part of the Amazon
hydrographic basin with a large number of rivers, among which is the Flexal River, a tributary
of the Matapi River, located on the border between the municipalities of Porto Grande and
Macapá, where the afro-descendant community of Thessalonica is located, this river being the
main means of transportation, water supply and fish for the local population. Specimens of the
fish Bryconops caudomaculatus, from the Flexal River, will be captured and transported alive
to the Morphophysiology and Animal Health Laboratory (LABMORSA) of the Amapá State
University (UEAP), where they will be anaesthetized, sacrificed and necropsied. Parasitological
analysis will take place using a stereomicroscope to observe the body surface in search of cysts
and to obtain organ fragments with signs of parasitism, confirmed by fresh examination under
an optical microscope with the sample on a slide and coverslip. The samples will then be fixed
and processed for histology, molecular biology, scanning electron microscopy and phylogenetic
analysis of eukaryotic microparasites. Preliminarily, the presence of spores belonging to the
Myxozoa class was observed, with structural characteristics for Myxobolus in various organs
and tissues, Henneguya in the integument, urinary bladder and gills and Meglitschia spores
infecting the gallbladder. Oocysts of the coccidian Calyptospora were also found parasitizing
the gallbladder and liver of Bryconops caudomaculatus. This study aims to describe the
morphology and ultrastructure of the microparasites found in fish from the Flexal River in the
community of Tessalônica, Amapá, Amazonia, Brazil.
