title: Diversity of parasites inCurimata incompta(Curimatidae), a host from Amazon river system in Brazil.
abstract: This paper is the first study on host-parasite relationship in wildCurimata incomptaVari, 1984 (Curimatidae) from Amazon river system, Northern Brazil. In 40 specimens examined from December 2012 to November 2013, 615,818 parasites were collected, such asIchthyophthirius multifiliis,Piscinoodinium pilullare,Urocleidoidessp.,Posthodiplostomumsp.,Gorytocephalus elongorchisandBraga patagonica. The parasites' component community had a low Brillouin diversity (0.16 ± 0.15), a low species richness (3.1 ± 0.7), a low evenness (0.09 ± 0.09) and a high dominance of Berger-Parker (0.96 ± 0.06).I. multifiliiswas the dominant parasite species and it showed the highest prevalence and intensity in the host population. There was an aggregate dispersion of parasites, but the low parasitism did not affect the body condition of the host. The occurrence of parasites inC. incomptawas due to their life habits and food behavior. This study, besides expanding the geographical distribution ofG. elongorchisin Brazil, records the first occurrence of these six parasites inC. incompta.
