| diversity of parasites in wild astronotus ocellatus (perciformes, cichlidae), an ornamental and food fish in brazil. | the community composition of parasites was characterized in astronotus ocellatus from a tributary of the amazon river, northern brazil. the prevalence was 87.9%, and a total of 526,052 parasites were collected, with a mean of 15,941 parasites per host. nine taxa of ecto- and endo-parasites were identified, but ichthyophthirius multifiliis was the dominant species, while piscinoodinium pillulare, clinostomum marginatum and argulus multicolor were the least prevalent parasites. the parasite commun ... | 2017 | 29044314 |
| structure of parasites community in chaetobranchopsis orbicularis (cichlidae), a host from the amazon river system in northern brazil. | the aim of this paper was to investigate the component communities of parasites in chaetobranchopsis orbicularis from a tributary of the amazon river system, in northern brazil. in 32 fish examined, 902,551 parasites were collected, including ichthyophthirius multifiliis, piscinoodinium pillulare, sciadicleithrum geophagi, posthodiplostomum sp., clinostomum marginatum, echinorhynchus paranensis, neoechinorhynchus pterodoridis, and dolops longicauda. i. multifiliis was the dominant and abundant p ... | 2017 | 28667520 |
| structure of the parasites communities in two erythrinidae fish from amazon river system (brazil). | this study compared the parasite communities of hoplias malabaricus and hoplerythrinus unitaeniatus from amazon river system. hoplias malabaricus were infected by ichthyophthirius multifiliis, piscinoodinium pillulare, tetrahymena sp., urocleidoides eremitus, braga patagonica, metacercariae of clinostomum marginatum, procamallanus (spirocamallanus) inopinatus, larvae of contracaecum sp. and larvae of nomimoscolex matogrossensis. hoplerythrinus unitaeniatus were also infected by these same specie ... | 2015 | 26083690 |
| seasonal pattern in parasite infracommunities of hoplerythrinus unitaeniatus and hoplias malabaricus (actinopterygii: erythrinidae) from the brazilian amazon. | the present study investigated the effects of seasonal variation in parasites infracommunities of hoplerythrinus unitaeniatus and hoplias malabaricus from a tributary of amazon river. for h. unitaeniatus and h. malabaricus, 11 parasite species were similar, and greatest parasite richness occurred during the rainy season. ichthyophthirius multifiliis was the dominant parasite species for both hosts. in h. unitaeniatus, infection by whittingtonocotyle caetei, whittingtonocotyle jeju, urocleidoides ... | 2016 | 26751882 |
| communities of parasite metazoans in piaractus brachypomus (pisces, serrasalmidae) in the lower amazon river (brazil). | the aim of this study was to investigate the component community of parasite metazoans of piaractus brachypomus in the lower amazon river, northern brazil. from 34 necropsied fish, 27,384 metazoan parasites were collected, such as anacanthorus spathulatus, mymarothecium viatorum and notozothecium janauachensis (monogenoidea); spectatus spectatus and contracaecum sp (nematoda); clinostomum marginatum and dadaytrema oxycephala (digenea); and argulus carteri and ergasilus sp. (crustacea). the domin ... | 2016 | 27334815 |
