Resumen:
Helminth community structure of Chirostoma attenuatum from two lakes of Michoacan State, Mexico, was analyzed and compared. Helminths from 72 fish were counted and collected for taxonomical determination. Helminthological record of C. attenuatum includes five species, three of them shared by fishes of both localities. Helminth communities are considered to be isolationist and depauperate due to the low values of richness, abundance and diversity obtained; the digenean Posthodiplostomum minimum was the species numerically dominant. We conclude that the differences observed in helminth community structure between localities are due to differential biotic and abiotic conditions; in Patzcuaro Lake, conditions favor the increase of fish-eating bird populations that serve as definitive hosts to allogenic species such as P. minimum.
