Thirty-six Brook Silversides, Labidesthes sicculus, and 15 Golden Silversides, Labidesthes vanhyningi, collected from the Ouachita and Red River drainage basins of Arkansas and Oklahoma, U.S.A., were examined for parasites. Six (17%) of the L. sicculus and 3 (20%) of the L. vanhyningi were infected with Dermocystidium sp., 1 (7%) L. vanhyningi harbored an immature tapeworm, Proteocephalus sp., and I (7%) L. vanhyningi was infected with the copepod Ergasilus fimduli. We document new host records for all 3 parasites as well as 2 new state records for Dermocystidium sp. and E. funduli. [ABSTRACT FROM AUTHOR]

The article presents a study that examined seventeen parasite species, including cestode, digeneans, and nematodes, that were recovered from fishes of genus Odontesthes smitti and Odontesthes nigricans in Argentina. Parasites such as Microsporidia, Cestoda, and Digenea, were found. Of the seventeen parasites collected, 14 were helminths, 2 were trematodes and there was a fungus. Component communities share most of the parasitic species.
