Aspectos parasitológicos da traíra (Hoplias malabaricus ) proveniente da cidade de São Bento, MA / Parasitologic aspects of traíra (Hoplias malabaricus) from the São Bento city, MA

ABSTRACT

The aim of this study was to verify the parasitologycal aspects of fish (Hoplias malabaricus), coming from São Bento city, Maranhão state. For this, 70 fish were used, verifying the parasitism indexes and coefficients. For the parasitological results nematodeos were identified, with zoonotical potential of the Contracaecum spp, Pseudoterranova spp, Eustrongylides spp; monogenetics Gyrodactirus spp, Dactylogirus spp and larva Acanthella of Acanthocephalo. Of the 70 (100%) fishes, 64 (91.4%) were sponged, with prevalence of 82.8% (58) for the nematodeo Contracaecum spp, 65.7% (46), Pseudoterranova spp, 7.1% (5), Eustrongylides spp, 71.4% (50), monogenetics and larva Acanthella of Acantocephalo, respectively. A maior amplitude de intensidade (1-30), coeficiente de variação foi verificado para o nematódeo Pseudoterranova spp., a intensidade média (7,3), índice de abundância (6,7), coeficiente de dominância (36,4) foi ao Contacaecum spp., todos os parasitos estavam no mesentério da cavidade abdominal, encistados em forma larval.The largest intensity width (1-30), variation coefficient was verified for the nematodeo Pseudoterranova spp, the medium intensity (7,3), abundance index (6,7), dominance coefficient (36,4) it went to the Contacaecum spp, all of the parasites were in the mesenterio of the abdominal cavity, encysted in larval form. The results show that fish from this region presented unsatisfactory sanitary conditions in parasitological aspect and can expose consumers to the risks of foodborne illnesses.(AU)
