| contents | A study on monogenean parasites from the gills of some cichlids (Pisces: Cichlidae) from the Brazilian Amazon Aristides Ferreira-Sobrinho Marcos Tavares-Dias Biología Amazon Helminths Monogenea Ectoparasites Freshwater fish The aim of this study was to investigate monogenean fauna in gills of Geophagus camopiensis, Pterophyllum scalare, Satanoperca jurupari, and Satanoperca acuticeps in a tributary from the Amazon River system in Brazil. A total of 2,148 monogenean specimens were collected from 140 fish examined from March 2012 to March 2013, and 84.3% of these fish were parasitized by 1 or more species. Such monogeneans were: Sciadicleithrum geophagi, Sciadicleithrum juruparii, Gussevia spiralocirra and Gyrodactylus sp. However, only G. camopiensis was parasitized by more than 1 species of monogenean, while S. jurupari and S. acuticeps were parasitized by the same species. Prevalence, mean intensity and mean abundance varied among host species and the highest levels of infection were by G. spiralocirra followed by S. geophagi, both parasites with aggregated dispersion. Abundance of monogeneans was not influenced by the size of the host. In G. camopiensis, the infection levels by S. geophagi did not vary during the rainy or drainage seasons. This is the first study on monogenean infections for G. camopiensis and S. acuticeps. 2016 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42547314013 https://www.redalyc.org/journal/425/42547314013/ https://www.redalyc.org/journal/425/42547314013/html/ https://www.redalyc.org/journal/425/42547314013/42547314013.epub https://www.redalyc.org/journal/425/42547314013/movil en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Num.3 Vol.87 |
