Genetic and morphological approaches distinguish the three sibling species of the Anisakis simplex species complex, with a species designation as Anisakis berlandi n. sp. for A. simplex sp. C (Nematoda: Anisakidae).

TLDR
The morphological and morphometric analyses revealed the presence of morphological features that differed among the 3 biological species, and the tree topologies support the finding that A. simplex (s.s.), A. pegreffii, and A. berlandi n.
Abstract
Numerous specimens of the 3 sibling species of the Anisakis simplex species complex (A. pegreffii, A. simplex (senso stricto)), and A. simplex sp. C) recovered from cetacean species stranded within the known geographical ranges of these nematodes were studied morphologically and genetically. The genetic characterization was performed on diagnostic allozymes and sequences analysis of nuclear (internal transcribed spacer [ITS] of ribosomal [r]DNA) and mitochondrial (mitochondrial [mt]DNA cox2 and rrnS) genes. These markers showed (1) the occurrence of sympatry of the 2 sibling species A. pegreffii and A. simplex sp. C in the same individual host, the pilot whale, Globicephala melas Traill, from New Zealand waters; (2) the identification of specimens of A. pegreffii in the striped dolphin, Stenella coeruleoalba (Meyen), from the Mediterranean Sea; and (3) the presence of A. simplex (s.s.) in the pilot whale and the minke whale, Balaenoptera acutorostrata Lacepede, from the northeastern Atlantic wa...

Molecular Epidemiology of Anisakis and Anisakiasis: An Ecological and Evolutionary Road Map.

TL;DR: This review addresses the biodiversity, biology, distribution, ecology, epidemiology, and consumer health significance of the so far known species of Anisakis, both in their natural hosts and in human accidental host populations, worldwide.

Effects of anisakid nematodes Anisakis simplex (s.l.), Pseudoterranova decipiens (s.l.) and Contracaecum osculatum (s.l.) on fish and consumer health ☆

TL;DR: Clinical symptoms associated with the infection, termed anisakidosis, vary from irritation of the oesophagus and stomach, via nausea, vomiting and diarrhoea to severe epigastric and abdominal pain.

Larval migration of the zoonotic parasite Anisakis pegreffii (Nematoda: Anisakidae) in European anchovy, Engraulis encrasicolus: Implications to seafood safety

TL;DR: Temperature plays an important role in the post-mortem motility of A. pegreffii larvae in anchovies, and the importance of the adoption of rules to prevent human anisakiasis was underlined.

Anisakis Nematodes in Fish and Shellfish- from infection to allergies

TL;DR: This review provides an update on current knowledge on Anisakis as a food-borne parasite with special focus on the increasingly reported diversity of fish and crustacean hosts, allergens and immunological cross-reactivity with invertebrate proteins rendering this parasite a significant public health issue.

A phylogeny of the Australian Sphenomorphus group (Scincidae: Squamata) and the phylogenetic placement of the crocodile skinks (Tribolonotus): Bayesian approaches to assessing congruence and obtaining confidence in maximum likelihood inferred relationships

TL;DR: Analysis of the combined data strongly supports Sphenomorphus group monophyly, with Tribolonotus placed as the sister taxon of the Australian Egernia group.

A Revision of the Genus Anisakis Dujardin, 1845 (Nematoda: Ascaridata)

TL;DR: By clarifying which taxonomic characters are of specific significance and by defining the intra specific limits of individual morphological variations, seventeen species of the genus Anisakis were shown to represent only three distinguishable forms, which were found to be satisfactory when discussed in geographical and ecological terms.

Molecular phylogenetics and diagnosis of Anisakis, Pseudoterranova, and Contracaecum from northern Pacific marine mammals.

TL;DR: Phylogenetic analysis of LSU sequences revealed strong support for the monophyly of Anisakinae, Contracaecum plus Phocascaris, Pseudoterranova, and Anisakis, which is primarily consistent with previously published phenograms based on multilocus electrophoretic data.
