摘要

This study investigated the metazoan parasite fauna in Peckoltia braueri and Pterygoplichthys pardalis from a tributary of the Amazon River system, in northern Brazil. In P. braueri , 630 parasites were collected, belonging to Unilatus unilatus , Nothogyrodactylus sp., Genarchella genarchella , Proteocephalus sp . , Gorytocephalus elongorchis , Dolops longicauda and Hirudinea gen. sp., with a dominance of monogenean species. In P. pardalis , 120 parasites were collected, belonging to U. unilatus , Acanthostomum gnerii and Gorytocephalus elongorchis , and this acanthocephalan was the dominant species. In both hosts, the parasites presented clumped distribution, high prevalence, low abundance, low Shannon diversity, and low species richness, with a predominance of helminth species. In P. braueri , host length was positively correlated with parasite species richness and Shannon index. There was no difference in the body condition of parasitized and non-parasitized fishes in either host. This was the first report of these parasites in P. braueri and P. pardalis .
