“…(AY994157), which was examined in Korea [ 23 ], clustered with a reference sequence of A. pegreffii (DQ 116428) in the phylogenetic analysis. This finding aligns with a previous study that analyzed the mitochondrial full genome [ 24 ]. The degree of identity with our newly generated A. simplex (s.s.) COX2 sequence was 95.4%.…”

The genus Anisakis is among the most significant parasites to public health, as it causes anisakiasis, a parasitic infection in humans resulting from consuming raw or undercooked seafood. Although the infection status of i>Anisakis in second intermediate hosts, such as marine fishes and cephalopods, and humans have been severally reported in Korea, no information about the definitive host in Korean waters is available. In 2014, 2 adult gastric nematodes were collected from a common minke whale (Balaenoptera acutorostrata) found in the East Sea, Korea. These worms were identified as A. simplex sensu stricto (s.s.) by comparing the mitochondrial COX2 marker with previously deposited sequences. Phylogenetic and phylogeographic analyses of A. simplex (s.s.) worldwide revealed 2 distinct populations: the Pacific population and the European waters population. This is the first report on adult i>Anisakis and its definitive host species in Korea. Further studies on Anisakis infection in other cetacean species and marine mammals in Korean seas are warrantedi>Anisakis

“…Second, a powerful argument for the reconsideration of taxonomic structure of A. simplex species complex was phylogenetic analysis performed using the mitogenome sequences of A. pegreffii , A. simplex sensu stricto , and A. berlandi . Three sibling species were distinctly separated from each other and this was also strongly supported by bootstrap values ( Yamada et al, 2017 ). Third, even gene loci coding metallopeptidase enables detection of fixed nucleotide positions (SNP) demonstration that A. pegreffii , A. simplex (s. s.), and A. berlandi are independent ( Palomba et al, 2020 ).…”

“…In current taxonomy there is a complex of species A. simplex sensu lato ( Mattiucci et al, 1997 ; Nascetti et al, 1983, 1986 ) which is made up of the three sibling species: A. simplex sensu stricto , A. pegreffii , and A. berlandi ( Mattiucci et al, 2014) . But, according to the available literature data a clear division of species ( A. simplex , A. pegreffii , and A. berlandi ) has been repeatedly demonstrated on phylogenetic trees reconstructed using nuclear ITS rDNA ( Pekmezci et al, 2014 ; Tunya et al, 2020 ) and mitochondrial cox2 gene ( Anshary et al, 2014 ; Barcala et al, 2018 ; Mattiucci et al, 2009 ; Setyobudi et al, 2011 ; Valentini et al, 2006 ) DNA markers, and finally complete mitochondrial genomes ( Yamada et al, 2017 ). Also A. typica (Diesing, 1860) is suspicious with its uncertain position on different phylogenetic reconstructions (Iñiguez et al, 2009; Sardella and Luque, 2016 ).…”

Alive anisakids cause acute gastrointestinal diseases, and dead worms contained in food can provoke sensibilization and allergic reactions in humans. Detected in the purchased minced salmon Oncorhynchus nerka nematodes were identified as Anisakis simplex sensu stricto (Anisakidae). We found that recently published phylogenetic trees (reconstructed using different ribosomal and mitochondrial genetic markers) showed independent clusterization of species recognized in the A. simplex sensu lato species complex. This prompted us to undertake this full-fledged molecular genetics study of anisakids from Kamchatka with phylogenetic reconstructions (NJ/ML) and calculated ranges of interspecific and intergeneric p-distances using ITS1-5.8S-ITS2 sequences. We confirmed that molecular markers based on the ITS region of rDNA were able to recognize 'pure' specimens belonging to the cryptic species. We offer new insights into the systematics of anisakids. The genus Anisakis sensu stricto should include Anisakis simplex sensu stricto, Anisakis pegreffii, Anisakis berlandi, Anisakis ziphidarum, and Anisakis nascettii. Presumably, two genera should be restored in the structure of the subfamily Anisakinae: Skrjabinisakis for the species Anisakis paggiae, Anisakis brevispiculata, and Anisakis physeteris; and Peritrachelius for the species Anisakis typica. In addition, we provide the short annotated list of some genera of the family Anisakidae, including their diagnoses.

“…The sequences with the highest similarity to Anisakis sp. 1 from warty squid belong to haplotypes NZ2–12 and Anisakis pegreffii from a chub mackerel from the coast of Japan (GenBank LC222461; Yamada et al ., 2017 ). These sequences showed 5.47 and 6.16% divergence respectively with Anisakis sp.…”

Large-scale genetic investigation of nematode diversity and their phylogenetic patterns in New Zealand's marine animals

Nematodes constitute one of the most speciose metazoan groups on earth, and a significant proportion of them have parasitic life styles. Zooparasitic nematodes have zoonotic, commercial and ecological significance within natural systems. Due to their generally small size and hidden nature within their hosts, and the fact that species discrimination using traditional morphological characteristics is often challenging, their biodiversity is not well known, especially within marine ecosystems. For instance, the majority of New Zealand's marine animals have never been the subject of nematode studies, and many currently known nematodes in New Zealand await confirmation of their species identity with modern taxonomic techniques. In this study, we present the results of an extensive biodiversity survey and phylogenetic analyses of parasitic nematodes infecting New Zealand's marine animals. We used genetic data to differentiate nematodes to the lowest taxonomic level possible and present phylogenies of the dominant clades to illustrate their genetic diversity in New Zealand. Our findings reveal a high diversity of parasitic nematodes (23 taxa) infecting New Zealand's marine animals (62 of 94 free-living animal species investigated). The novel data collected here provide a solid baseline for future assessments of change in diversity and distribution of parasitic nematodes.
