إنجليزي. Abstract Infection of fish gills by Henneguya causes greater contact between the secondary gill lamellae, thereby giving rise to decreased absorption surface area at the end of the filaments. This ectoparasite can cause damages on the gills infected fish. In the present study, fresh gills of Metynnis lippincottianus were analyzed using optical microscopy techniques. The myxoporean Henneguya sp. was found to be infecting 80% of the gills of this host fish. Presence of this parasite caused hyperplasia and fusion of the gill lamellae, but without inflammation in the parasitized organ.

Provoca diminuição da superfície de absorção na extremidade dos filamentos, podendo ocasionar danos as brânquias dos peixes infectados. Neste estudo foram analisadas a fresco e com técnicas de microscopia de luz as brânquias de Metynnis lippincottianus. Foi determinada a presença de mixosporídeos Henneguya sp. infectando 80% das brânquias dos peixes hospedeiros. A presença desse ectoparasito causou hiperplasia e fusão das lamelas branquiais, porém sem inflamação no órgão parasitado.
