This paper describes the prevalence, mean intensity, molecular phylogeny, ultrastructure, and histology of H. piaractus and M. cf. colossomatis found infecting specimens of P. mesopotamicus collected from fish farms in the state of São Paulo, Brazil. A total of 278 fish were collected from 3 fish farms between February 2008 and July 2010. Parasite prevalence and mean intensity varied throughout the study period, and according to location and year. A phylogenetic tree, placing South American species in a global context, showed a clear tendency among myxosporean species to cluster according to host families. Ultrastructural analysis for M. cf. colossomatis showed the plasmodial wall with numerous projections toward host cells and phagocytic activity. Histopathological data showed hyperplasia caused by H. piaractus in highly infected fish. Histological and ultrastructural analysis of H. piaractus showed results similar to those that have previously been reported.
