Anisakid larvae in the skipjack tuna Katsuwonus pelamis captured in Japanese waters: Two-year monitoring of infection levels after the outbreak of human anisakiasis in 2018.

Abstract
In 2018, human anisakiasis caused by the ingestion of the skipjack tuna Katsuwonus pelamis occurred frequently in Japan. This may be attributable to a heavy infection of A. simplex (s.s.) in the host's muscle tissue. In this study, we investigate infection levels of anisakid L3 larvae in skipjack tuna captured in Japanese waters afterward (2019-2020) to contribute to predict and prevent the outbreak of human anisakiasis. A total of 476 larvae were detected from 78 out of 85 skipjack tuna captured at 14 stations of the Pacific and East China Sea. The present parasitological survey suggests that infection levels in 2019-2020 were low, comparing that in 2018; in total only seven larvae were found from the host's muscle tissue. The collected larvae were identified by molecular methods to Anisakis berlandi, A. pegreffii, A. simplex (s.s.), A. typica and Skrjabinisakis physeteris (s.l.). Not only larvae of A. simplex (s.s.) but also those of A. berlandi were found from the muscle tissue and thus the latter species may also be a causative agent of human anisakiasis. In addition, this study confirmed the geographic distribution pattern that A. simplex (s.s.) is abundant in the Pacific, while A. pegreffii is dominant in the East China Sea. Our results contribute to understanding the risk of food poisoning and stock delimitation of host animals.

Temporal change in the parasite community of an invasive fish Trachelyopterus galeatus (Siluriformes: Auchenipteridae) in a neotropical floodplain. Parasitol Res 2024; 123:270.

Abstract
The construction of dams and hydroelectric plants affects biodiversity in aquatic environments and can facilitate the invasion of species. Few studies assess the long-term response of parasite fauna under these events. The aim of this study was to investigate possible changes in the endoparasite composition of the invasive catfish Trachelyopterus galeatus (Linnaeus, 1766) in the floodplain of the upper Paraná River over a 27-year study period. A total of 79 fish were collected in period 1 (1993) and 31 in period 2 (2019/2020) at the same sampling points, and the endoparasites were located in the gastrointestinal system using a stereomicroscope. It was found that the development of the fish and the composition of their endoparasitic fauna changed over time. In the second period, the fish presented smaller values for mass (g) and standard length (cm) when compared to period 1. It was found that three species of endoparasites were found per period, but although the richness was the same, the composition differed, and only one digenean (Microrchis oligovitellum Lunaschi, 1987 (Trematoda: Paramphistomidae)) was shared. The Porto Primavera Dam was built upstream of the site between the sampling periods (1999) and caused a number of environmental changes, possibly being the main factor responsible for changes in components of the parasite community. Anthropic modification to an environment can cause loss of diversity and loss of ecological interactions. Through our results, we emphasize the importance of including parasite fauna in studies that assess environmental impacts.

Abstract
Parasitic fauna of the White Sea cod, Gadus morhua marisalbi; the navaga, Eleginus nawaga; and the shorthorn sculpin, Myoxocephalus scorpius, in the White Sea was repeatedly studied, but no large-scale parasitological surveys have been made in the recent three decades. To fill this gap, we conducted a survey of the helminths of these three fish species at the White Sea Biological Station (Karelia, Russia) of the Lomonosov Moscow State University in August 2021. The navaga (50 specimens studied) was found to be infected with 13 species of helminths; the White Sea cod (50 specimens), with 12 species; and the shorthorn sculpin (21 specimens), with 13 species. Plerocercoids of Diphyllobothrium schistochilus and third-stage juveniles of Pseudoterranova bulbosa were recorded in the White Sea for the first time. The helminth infracommunities of the navaga and the White Sea cod were closer in structure to each other than to those of the shorthorn sculpin. In general, the levels of helminth infection of the White Sea cod, the navaga, and shorthorn sculpin have been consistently high over 85 years of observations in the White Sea, but long-term trends in the abundance of some helminth species were multidirectional.

Prevalence of Anisakis larvae in cultured mackerel Scomber japonicas in Japan and the relationship between the intensity of Anisakis infection in cultured mackerel and fish fatness. Int J Food Microbiol 2023; 404:110347. [PMID: 37543025 DOI: 10.1016/j.ijfoodmicro.2023.110347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 06/26/2023] [Accepted: 07/28/2023] [Indexed: 08/07/2023]
Abstract
Incidences of food poisoning caused by Anisakis have increased in Japan, and a significant number of anisakiasis cases in Tokyo attributed to the consumption of mackerel (Scomber japonicus) have been reported. There are two types of cultured mackerel in Japan: those cultured fully from controlled parent fish eggs and those cultured from wild juveniles collected from the sea. In this study, we aimed to investigate the prevalence of Anisakis larvae in cultured mackerel (184 fish) in 15 products and identified the species using molecular analysis to evaluate the risk of food poisoning. In total, 1567 Anisakis larvae were detected in 70 of 130 mackerel in 10 products; however, Anisakis larvae were not detected in 54 mackerel using artificially reared juveniles in 5 products. Moreover, 277 larvae were detected in fish muscle, and 98.6 % (273/277 larvae) were molecularly identified as Anisakis simplex sensu stricto (A. simplex). Conversely, 1043 Anisakis pegreffii larvae were identified genetically and/or morphologically but only 2 larvae were identified in the muscle. There was no significant relationship between the host coefficient of fatness and the infection intensity of Anisakis larvae in individual fish (Spearman's rank correlation coefficient test, P > 0.05). Based on the results of the analysis of the cytochrome c oxidase subunit2 (cox2) gene of A. simplex and A. pegreffii detected in this study, we attempted to estimate the catch area of the juveniles (Pacific stock and Tsushima Warm Current stock). The clusters on the phylogenetic tree of the cox2 gene of A. pegreffii from the mackerel presumed to be the two above mentioned geographic distributions were not separated and these geographic origins could not be estimated. This study revealed that mackerel cultured using wild juveniles are likely to be contaminated with Anisakis larvae, which can be detected not only in the visceral organs, but also in the muscle. Anisakis infection in cultured mackerel did not influence fish growth and evaluating the intensity of Anisakis based on the fatness level of the mackerel was complicated. To prevent anisakiasis caused by the consumption of mackerel cultured using wild juveniles, it is important to steadily control Anisakis through heating and freezing.

Abstract
Fish parasitological research associated with fisheries and aquaculture has expanded remarkably over the past century. The application of parasites as biological tags has been one of the fields in which fish parasitology has generated new insight into fish migration and stock assessments worldwide. It is a well-established discipline whose methodological issues are regularly reviewed and updated. Therefore, no concepts or case-studies will be repeated here; instead, we summarize some of the main recent findings and achievements of this methodology. These include the extension of its use in hosts other than bony fishes; the improvements in the selection of parasite tags; the recognition of the host traits affecting the use of parasite tags; and the increasingly recognized need for integrative, multidisciplinary studies combining parasites with classical methods and modern techniques, such as otolith microchemistry and genetics. Archaeological evidence points to the existence of parasitic problems associated with aquaculture activities more than a thousand years ago. However, the main surge of research within aquaculture parasitology occurred with the impressive development of aquaculture over the past century. Protozoan and metazoan parasites, causing disease in domesticated fish in confined environments, have attracted the interest of parasitologists and, due to their economic importance, funding was made available for basic and applied research. This has resulted in a profusion of basic knowledge about parasite biology, physiology, parasite-host interactions, life cycles and biochemistry. Due to the need for effective control methods, various solutions targeting host-parasite interactions (immune responses and host finding), genetics and pharmacological aspects have been in focus.

Abstract
Nematode parasites of the genus Anisakis (Nematoda, Anisakidae) are considered among the most important biological hazards in seafood products worldwide. In temperate and tropical waters, the most common species appears to be Anisakis typica, generally found around the viscera and sporadically in the flesh of various fish host species. This study investigated the infection sites and genetic diversity of A. typica infecting commercial fishes from the South-West Indian Ocean. Largehead hairtail (N = 20) and brushtooth lizardfish (N = 72) fished off Tanzania were inspected for anisakid nematodes by UV-press. A subsample of 168 nematodes were identified by sequence analyses of the cox2 mtDNA gene and ITS region of rDNA. The species A. typica (s.l.) (N = 166), Pseudoterranova ceticola (N = 1) and Anisakis paggiae (N = 1) were molecularly identified. Phylogenetic analysis of A. typica (s.l.) sequences based on both genes, indicated the existence of two distinct phylogenetic lineages forming two well-supported clades. The first clade comprised 12 A. typica specimens including individuals from its type locality (central Atlantic Ocean). The second clade comprising 154 specimens, clustered with reference sequences retrieved from GenBank including one apparently undescribed taxon, i.e., Anisakis sp. 1, and A. typica var. indonesiensis. The two reciprocally monophyletic clades are closely related and correspond to two distinct sister species within A. typica (s.l.), presently indicated as A. typica sp. A and A. typica sp. B. Two and four fixed alternative nucleotide substitutions (SNPs), i.e., diagnostic positions, between the two taxa, respectively, were found at the mtDNA cox2 and the ITS region of rDNA. The genetic data, as well as their occurrence in sympatry, strengthens the hypothesis that the actual specimens represent two distinct gene pools. The occurrence of both A. typica sp. A and A. typica sp. B in the musculature of freshly examined T. lepturus and S. undosquamis, suggests that both species can migrate intra-vitam into the flesh. Although the zoonotic potential of A. typica s.l. is still unclear, the presence of these parasites in the musculature, edible part of the fish, raises health concerns for consumers. Phylogenetic analyses suggest the existence of two sister species within A. typica (s.l.). typica sp. A and sp. B can both migrate intra-vitam into the fish flesh. Occurrence of A. typica (s.l.) larvae in the fish flesh may raise food safety concerns.

Multigene phylogenetic analysis reveals non-monophyly of Anisakis s.l. and Pseudoterranova (Nematoda: Anisakidae). Parasitol Int 2022; 91:102631.

Abstract
The nematode genera Anisakis s.l. and Pseudoterranova (Anisakidae) include causative agents of anisakiasis and pseudoterranovosis, parasitic diseases resulting from eating undercooked or raw fish or squid. Species in both genera have thus attracted considerable attention especially in public health and taxonomic studies. The phylogenetic relationships of these genera within the subfamily Anisakinae, however, remain to be investigated with dense taxonomic sampling. In this study, we collected an anisakid third-stage larva, and identified it morphologically and molecularly as Pseudoterranova ceticola. Phylogeny of 15 anisakine species, including the newly collected specimen of Ps. ceticola, was reconstructed based on sequences of three mitochondrial (cox1, cox2, and 12S rRNA) and two nuclear (ITS and 28S rRNA) regions. The obtained tree suggested the non-monophyly of Anisakis s.l. and Pseudoterranova. Anisakis s.l. was divided into two groups, which are distinguished from each other by the shape of the ventriculus. Based on phylogenetic relationships and morphology, three species with a shorter ventriculus ("A." brevispiculata, "A." paggiae, and "A." physeteris) were assigned to the genus Skrjabinisakis, as recently proposed. Pseudoterranova ceticola was distantly related to the monophyletic Ps. decipiens species complex. Although the phylogenetic position of the type species Ps. kogiae has not been investigated due to a lack of sequence data, this species may morphologically and ecologically resemble Ps. ceticola, inferring a close kinship between the two species.

Abstract
Parasitic ascaridoid nematodes occur in a wide range of marine organisms across the globe. Some species of the anisakid family (Ascaridoidea: Anisakidae) can cause gastrointestinal disease in humans (i. e. anisakidosis). Despite their importance as potentially hazardous parasites, the occurrence and infection characteristics of ascaridoids are still poorly known from many host species and geographical areas. This study investigated the diversity and infection levels of ascaridoid parasites in various commercial fish and squid host species off Bangladesh. Fish and squid specimens were visually inspected for nematodes using the UV-press method. Nematodes were assigned to genus level based on morphology and identified by sequence analyses of the entire ITS region and partial 28S rDNA and mtDNA cox2 genes. Third-stage larvae (L3) of Anisakis typica occurred at low prevalence (P = 10% and 8%, respectively) in the viscera of Selar crumenophthalmus and Trichiurus lepturus, while Hysterothylacium amoyense occurred in the viscera of Sardinella fimbriata (P = 1%) and the viscera and muscle of Harpadon nehereus (P = 32%) and T. lepturus (P = 76%). Lappetascaris sp. Type A L3 occurred in the mantle of the squid Uroteuthis duvaucelii (P = 11%). Anisakis and Lappetascaris species, and H. amoyense were firstly identified in the Bay of Bengal. The potentially zoonotic A. typica was only found in fish viscera. Hysterothylacium amoyense and Lappetascaris sp., both generally regarded as non-zoonotic, occurred at low prevalence in the muscle or mantle of fish or squid, respectively. Since consumption of raw or lightly processed seafood seems to be rare in Bangladesh, the risk of acquiring anisakidosis from consuming fishery products from off Bangladesh appears to be low. Due to its reddish appearance, the visual presence of H. amoyense larvae in fish flesh may represent a food quality issue.

Abstract
Scombridae fish (tuna, bonito, and mackerel) have significant ecological and economic values. They are very appreciated by consumers worldwide for their high-quality flesh and for their high nutritional value. However, consumption of Scombridae fish is potentially hazardous. Indeed, several cases of infections and toxicity linked to the consumption of Scombridae fish as raw, or processed food products have been reported worldwide. In this review, we presented the most common health risks associated with Scombridae fish consumption. Diseases associated with the consumption of these fish are generally infectious or toxic and are caused by biological hazards such as bacteria, viruses, parasites, or chemicals hazards that enter the body through contaminated fish (Polycyclic Aromatic Hydrocarbons, histamine) or by physical contaminants such as heavy metals. The risks of contamination exist throughout the food chain, from primary production to the preparation of products for consumption.
