- Detection of Anisakidae larvae parasitizing Plagioscion squamosissimus and Pellona castelnaeana in the State of Pará, Brazil Núbia Lorena Farias Rabelo Thatyana Cristina Muniz e Silva Laudemir Roberto Ferreira Araujo Raul Henrique da Silva Pinheiro Carlos Alberto Machado da Rocha Biología zoonosis Anisakidae Amazon basin Freshwater fish Five specimens of Plagioscion squamosissimus from Xingu River and ten specimens of Pellona castelnaeana from Mosqueiro Island, both in the State of Pará, Brazil, were examined to investigate the presence of anisakid nematodes, due to their zoonot ic potential. Their parasi tism indices and sites of infection were also determined. This is th e first record of Anis akidae parasitizing Pellona castelnaeana . Four- hundred and eighty-four third-stage larvae (L 3 ) of Anisakidae were found, of which 42 were found in P. squamosissimus and 442 in P. castelnaeana . The parasitism indices of the anisakid collected from the P. squamosissimus comprised prevalence (P) of 100%, mean infectio n intensity (MI) of 8.4, range of infection (RI) of 1-13, mean abundance (MA) of 8.4, an d infection site (IS) in the abdominal cavity. P. castelnaeana showed P = 100%, MI = 44.2, RI = 10-114, MA = 44.2, and IS = abdominal cavity, cecum and stomach. The life cycle of these nematodes can be completed in the Amazon basin, since the two hosts fish are part of the cetacean diet of the region, which participate as final hosts. These findings have an important consequence on epidemiology of anisakiasis, so attent ion should be extended to human protection against this public health risk. 2017 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187152898014 https://www.redalyc.org/journal/1871/187152898014/ https://www.redalyc.org/journal/1871/187152898014/html/ https://www.redalyc.org/journal/1871/187152898014/187152898014.epub https://www.redalyc.org/journal/1871/187152898014/movil en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
