Myxosporids and nematodes in Hemiodopsis microlepis (Teleostei: Hemiodontidae) of the Gurguéia River, Bom Jesus-Piauí, Brazil. Rev. Med. Vet. [online]. 2018, n.36, pp.89-96.

The objective of this study was to carry out an ichthyoparasitological study on the species Hemiodopsis microlepis (archerfish) of the Gurguéia River, located in Bom Jesus Piauí, Brazil. Thirty specimens of Hemiodopsis microlepis were collected, which underwent an external morphological analysis and collection of small fragments of gills, liver, kidneys, and intestines to identify the parasites Myxobolus sp., Henneguya sp., and Camallanus sp., using an optical microscope (40X). About 90% of the examined fish were parasitized by myxosporids belonging to the Myxobolidae family, of which around 20% were parasitized by Henneguya sp., and 70% were parasitized by Myxobolus sp. Only 5% of the specimens parasitized by Myxobolus sp. were also parasitized by nematodes. The ichthyoparasitological study of the species Hemiodopsis microlepis confirmed the presence of the parasites Myxobolus sp. and Henneguya sp., as well as the nematodes of the species Camallanus sp.
