LarvalAnisakis sp. (Ascaridoidea, Anisakidae) from the coelacanth,Latimeria chalumnae

Environmental Biology of Fishes, 1993
A third-stage larva ofAnisakis sp. was found coiled and encapsulated on the mesentery of a 168 cm long coelacanth female (CCC no. 154) examined at Guelph in 1992. The larva was 8.4 mm in length and 300 μm in maximum width. The oesophagus was 820 μm and the ventriculus about 310 μm in length (Fig. 1a).

Development of Porrocaecum ensicaudatum (Nematoda: Ascaridoidea) in terrestrial oligochaetes

Canadian Journal of Zoology, 1990
Development of Porrocaecum ensicaudatum (Zeder, 1800) in the egg was studied at 5–10, 23–26, and 32–35 °C. Embryonic development occurred at 23–26 and 32–35 °C, but ceased at 5–10 °C. Development resumed in eggs transferred from the cold temperature to 23–26 °C.

Species of Typhlophoros von Linstow, 1906 (Nematoda: Ascaridoidea) in Old World crocodilians

Systematic Parasitology, 1999
A new species of the genus Typhlophoros von Linstow, 1906, T. spratti, is described from the freshwater crocodile Crocodylus johnstoni and the saltwater crocodile C. porosus in northern Australia. Specimens of the new species could not be compared with the type-species, T.

Stimuli for cuticle formation and ecdysis in vitro of the infective larva of Anisakis sp. (Nematoda: Ascaridoidea)

International Journal for Parasitology, 1976
Third-stage larvae of the genus Anisakis from the fish Leionura atun (Trichiuroidei: Perciformes) form a new cuticle and moult in vitro in about 72 h. If the culture medium is Krebs-Ringer under 5% carbon dioxide in air at 37°C, relatively few moult and survival is poor.

Allozyme and morphological identification of shape Anisakis, Contracaecum and Pseudoterranova from Japanese waters (Nematoda, Ascaridoidea)

Systematic Parasitology, 1998
Allozyme markers were used to identify anisakid nematodes from marine Japanese waters, morphologically assigned to three species complexes: Anisakis simplex (s. l.), Contracaecum osculatum (s. l.) and Pseudoterranova decipiens (s. l.). Samples assigned to A. simplex (s. l.) were found to correspond genetically to A.

Genetic and Ecological Data on the Anisakis simplex Complex, with Evidence for a New Species (Nematoda, Ascaridoidea, Anisakidae)

The Journal of Parasitology, 1997
Isozyme analysis at 24 loci was carried out on anisakid nematodes of the Anisakis simplex complex, recovered from various intermediate/paratenic (squid, fish) and definitive (marine mammals) hosts from various parts of the world. A number of samples were found to belong to A. simplex sensu stricto and Anisakis pegreffii, widely extending the geographic

Growth of whaleworm (Anisakis simplex, Nematodes, Ascaridoidea, Anisakidae) third-stage larvae in paratenic fish hosts

Parasitology Research, 2003
The growth of Anisakis simplex L3 larvae in the three paratenic hosts saithe ( Pollachius virens), cod (Gadus morhua) and redfish (Sebastes marinus) was studied based on material collected off the island of Vega on the west coast of Norway over a period of 1 year.

[Evolutionary aspects of the distribution of Ascaridoidea in mammals (author's transl)].

Annales de parasitologie humaine et comparee, 1977
In an attempt to interpret the distribution of Ascaridoidea in Mammals and Birds, a scheme is proposed, based on the concept of geological periods of evolutionary expansion for parasitic lines. It is assumed that the evolutionary expansion period of Ascaridoidea in Mammals occurred after the diversification of primitive mammals; this would explain the ...
