Nas últimas décadas houve um aumento significativo dos casos de zoonoses transmitidas pelo consumo de pescado cru ou mal cozido no Brasil. Entre julho e agosto de 2015 foram adquiridos 10 espécimes de bacalhau (Gadus morhua)(Osteichthyes: Gadiformes: Gadidae) provenientes de supermercados do Município de Volta Redonda, Estado do Rio de Janeiro, Brasil. Os espécimes foram analisados com o objetivo de identificar e registrar os parasitos de potencial zoonótico. As análises do pescado foram realizadas no Laboratório de Técnica Dietética do Curso de Nutrição UniFOA. Foi constatada a presença de larvas de Anisakis simplex (L3) em todas as amostras examinadas. Um total de 652 larvas foi coletado, com média de 65,2 ± 33,7 (17 – 113) parasitos por amostra examinada. As larvas encontravam-se encapsuladas, enroladas em espiral plana, sob o peritônio e a pele e inseridos na musculatura das amostras de bacalhau. A presença dessas larvas nas amostras do bacalhau analisadas as torna impróprias para o consumo.

Desde Octubre hasta Marzo, 2006, 60 ejemplares de Paralichthys isosceles fueron colectados en el litoral del Estado do Rio de Janeiro, Brasil, con el objetivo de hacer un inventario de nematodos anisákidos considerando su importancia en las zoonosis. Cinco especies larvales son representadas con un total de 1.900 parásitos, siendo 1.850 muestras de Hysterothylacium sp., 71 de Raphidascaris sp., cuatro of Terranova sp., tres de Anisakis simplex y dos de Contracaecum sp. Los parásitos fueron encontrados en la cavidad abdominal, mesenterio, intestino, hígado, mucosa estomacal, estomago, ovarios, musculatura abdominal, y en las serosas del corazón, bazo, estomago, riñones y ovarios. Larvas de Hysterothylacium sp. aparecieron con una prevalencia (P) de 100%, intensidad media (MI) de 30,3, amplitud de intensidad (RI) de 1 a 596 y abundancia media (MA) de 32, Raphidascaris sp. con P = 39%, MI = 3,2, RI = 1 a 29 y MA= 1,2, Anisakis simplex con P = 5%, Intensidad (I) = 1 y MA= 0,06, Terranova sp. con P = 5%, (I) = 1 y MA= 0,05, Contracaecum sp. con P = 3,0%, I =1 y MA = 0,03. Este es el primero reporte de índices parasitarios y sitios de infección de larvas de A. simplex, Contracaecum sp. Terranova sp., Hysterothylacium sp. y Raphidascaris sp. en Paralichthys isosceles que es un nuevo registro de hospedero para larvas de Anisakis simplex y Hysterothylacium sp.

Examination Method

Larvae of Anisakis simplex were found in the flesh of Atlantic cod, Gadus morhua, collected in 21 regions around Newfoundland and Labrador during 1985–87. Prevalence and abundance increased with cod size and varied geographically; cod off Labrador had the fewest larvae whereas those from the south coast of Newfoundland were the most heavily infected. Most larvae (~95%) occurred in flesh surrounding the body cavity (napes), with a significantly higher percentage of the nematodes (~58%) in the flesh on the left side. In 505 cod in which all tissues were examined, 85.6, 10.8, and 3.5% of the A. simplex resided in the body cavity and viscera, napes, and fillets, respectively. Cod surveyed tended to have more A. simplex in the musculature than those from other areas off eastern Canada, but are lightly infected compared with most other Atlantic cod stocks. The examination method (candling combined with slicing) recovered, on average, 42% of the A. simplex present in the flesh; consequently, infection statistics reported here are underestimates. Numbers of A. simplex in cod off Labrador and eastern Newfoundland are similar to those observed during 1947–53, but the abundance of A. simplex appears to have increased among cod from NAFO Subdivision 3Pn.

AbstractCod (Gadus morhua), an important fish species in the Baltic Sea, is the paratenic host for many parasite species, including the zoonotic nematodes, Anisakis sp. and Contracaecum osculatum. We aimed to identify which invertebrate species (found in situ in the fish stomach) are responsible for infection of cod with zoonotic nematodes. We found that Crangon crangon and Gammarus sp., both invertebrate prey species of cod, were infected with Anisakis simplex and C. osculatum, respectively. These host–parasite systems are reported here for the first time, implicating C. crangon and Gammarus sp. as sources of infection of Baltic cod with zoonotic nematodes.

Hippoglossoides Platessoides

Atlantic cod (Gadus morhua) and American plaice (Hippoglossoides platessoides) collected from various sites in the Gulf of St. Lawrence (NAFO divisions 4RST) were examined for larval anisakine nematodes in 1990 and 1992. Sealworm larvae (Pseudoterranova decipiens) were more abundant in southern Gulf (4T) than in northern Gulf (4RS) cod and plaice. The heaviest sealworm infections occurred in fish from St. Georges Bay, Nova Scotia. Abundance of P. decipiens in cod from St. Georges Bay was significantly lower in 1992 than in 1990. Anisakis simplex and Contracaecinea (Contracaecum/Phocascaris spp.) were most abundant in cod from the northern Gulf. American plaice were not heavily infected with A. simplex or Contracaecinea. Geographical and temporal variations in abundance of larval anisakine nematodes in fish may reflect distribution and abundance of the phocid and cetacean definitive hosts and variations in water temperatures.
