“…are of public health importance because they are responsible for emerging diseases such as anisakiasis, which affects humans after consuming raw or poorly cooked fish dishes, such as sushi, sashimi and ceviche (MINETA et al, 2006;FELIZARDO et al, 2009). No cases of this have been reported in humans in Brazil, although there have been reports of occurrences of larvae of anisakids in various fish (BARROS et al, 2006(BARROS et al, , 2007SAAD & LUQUE, 2009;KNOFF et al, 2013;MATTOS et al, 2014).

This study has evaluated the parasitic fauna of 79 pearl cichlids (Geophagus brasiliensis) from the estuary of Patos Lagoon (31° 57' S and 52° 06' W), Rio Grande do Sul, Brazil, during the months of May and June in 2011 and 2012. All the hosts analyzed were infected with at least one species of parasite. A total of eleven metazoa were identified in 459 specimens collected. The trematode Austrodiplostomum compactum (34.2%) and ergasilids Ergasilus lizae (32.9%) and Gauchergasilus lizae (32.9%) were the most prevalent species. The trematodes Thometrema overstreeti and Posthodiplostomum sp. had significantly higher prevalence in fish longer than 20 cm. The sex of the host had no effect on parasite prevalence and abundance. Pearl cichlids are registered as a new host for the trematodes Lobatostoma sp., Homalometron pseudopallidum and Thometrema overstreeti, for the ergasilids Ergasilus lizae and Gauchergasilus euripedesi and for the argulid Argulus spinolosus. The crustacean E. lizae is recorded in Rio Grande do Sul for the first time.

“…However, several authors have reported the presence of these parasites in marine fish, generally in greater prevalences in comparison with other helminths (São Clemente et al, 1994;Luque, 2004;Knoff et al, 2007Knoff et al, , 2013Barros, 2012). Anisakid larvae have been reported by several authors in species of fish of economic importance such as: Anchoa tricolor, Netuma barba, Brevoortia aurea, Pagrus pagrus, Prionotus punctatus, Genypterus brasiliensis, Aluterus monoceros, Paralichthysis isoceles, Rhamdia quellen, Lophius gastrophysus, Lutjanus analis, Sardinella brasiliensis, and Selene setapinnis (Palm, 1997;São Clemente et al, 1994;Cordeiro and Luque, 2004;Bicudo et al, 2005;Knoff et al, 2007;Saad and Luque, 2009;Dias et al, 2010;Felizardo et al, 2009;La Rue et al, 2010;Saad et al, 2012;Knoff et al, 2013;Hermida et al, 2014;Moreira et al, 2015;Fontenelle et al, 2015).…”

“…The presence of these larvae in the fish's skeletal muscle is characteristic of some genera of the family Anisakidae. Anisakid larvae may migrate naturally to fish muscle tissue as a result of postmortem changes that occur in the host or when fish are subjected to freezing (Eiras et al, 2006;Saad and Luque, 2009;Andrade-Porto et al, 2015).…”

Abstract The present study aimed at describing and evaluating the fauna of Anisakidae and Raphidacarididae nematodes of lutjanid fish (snappers) from the Brazilian northeastern coast unloaded at the city of Aracaju, capital of the State of Sergipe. A total of 186 lutjanids of 5 different species were analyzed including 69 Lutjanus analis, 51 L. vivanus , 29 Ocyurus chrysurus, 23 L. synagris, and 14 L. jocu. Nematode specimens found in the viscera of these fish were clarified with lactophenol. Illustrations of each of these specimens were prepared to help identify these samples and compose their taxonomic description and classification. At necropsy, 3,183 nematodes belonging to two families were collected from fish viscera which included the following: Anisakidae: Anisakis, Terranova , Contracaecum, and Goezia; Raphidascarididae: Raphidascaris (Ichthyascaris) and Hysterothylacium . A total of six genera of nematodes were found at postmortem examination of which adult worms of only three genera (Goezia, Raphidascaris and Hysterothylacium) were detected in the fish examined. Larvae of Terranova sp. were found only in the musculature of O. chrysurus . Most of the nematode larvae were present in the mesentery and organs of the fish necropsied. Therefore, the zoonotic potential of these nematodes cannot be ruled out. There was a significant negative correlation between the intensity of parasitism by anisakids and the total body length of O. chrysurus; the intensity of parasitism was greater in smaller and shortef fish. There was a significant positive correlation between the abundance of these parasites and the length of L. synagris; the presence of these parasites increased according to the fish’s body length. To the authors’ knowledge, these are the first records of Raphidascaris (Ichthyascaris ) sp. and Hysterothylacium sp. in L. vivanus , of Terranova sp. in O. chrysurus and L. jocu, and of Goezia sp. in L. analis. These novel findings add the Brazilian northeast coast and the State of Sergipe in the geographic distribution of these parasites in the country.

Taking into account the difficulties of taxonomic identification of larval anisakid nematodes based on morphological characters, genetic analyses were performed, together with those usually applied, in order to identify anisakid larvae found in the flounder Paralichthys isosceles from the littoral of the state of Rio de Janeiro, Brazil. The analysis of 1,820 larvae revealed a new species, similar to Hysterothylacium MD, Hysterothylacium 2, Hysterothylacium KB and Hysterothylacium sp regarding the absence of the larval tooth, an excretory pore situated below the nerve ring level, and slender lateral alae. Moreover, the new species differs from Hysterothylacium fortalezae and Hysterothylacium reliquens with regard to the number and size of spines present on the tail end and from Hysterothylacium patagonicus by the absence of interlabia. The maximum parsimony and neighbour joining tree topologies based on the 18S ribosomal DNA gene, complete internal transcribed spacer region and cytochrome oxidase 2 (COII) gene demonstrated that the Brazilian larvae belong to Raphidascarididae and represent a unique genetic entity, confirmed as a new Hysterothylacium species. Furthermore, the new species presents COII genetic signatures and shares polymorphisms with Raphidascarididae members. This is the first description of a new anisakid species from Brazil through the integration of morphological and molecular taxonomy data
