Centrids, a Pair of Asymmetrically Arranged Sense Organs in Ascaris suum (Nematoda, Ascaridoidea)

The Journal of Parasitology, 1999
Two prominent, asymmetrically placed cuticular somatic sensilla, called centrids, are reported in Ascaris suum Goeze, 1782, the pig roundworm. The right centrid is situated much more anteriorly on the body than is the left one. The centrids are globular in the fourth-stage larva and obviously void of an apical pore, suggesting at least a tactile ...

Electrophoretic detection of population variation withinContracaecum ogmorhini (Nematoda: Ascaridoidea: Anisakidae)

ELECTROPHORESIS, 2001
This study examined genetic variation among specimens of Contracaecum ogmorhini from different otariid hosts and geographical origins using a polymerase chain reaction (PCR)-based mutation detection approach. The first (ITS-1) and second (ITS-2) internal transcribed spacers (ITS) of ribosomal DNA (rDNA) were amplified individually by PCR, scanned for ...

First report of a morulated Ascaridoidea (Nematoda) egg in an avian coprolite from the Paleogene of the Paraíba Valley, State of São Paulo, Brazil

Journal of Helminthology
Ascaridoidea (Nematoda) is a widespread superfamily of nematodes that comprises gastrointestinal parasites from all major groups of vertebrates. Although this taxon probably emerged in the Carboniferous, its Brazilian fossil record includes mostly eggs ...

Anisakid and raphidascaridid nematodes (Ascaridoidea) infection in the important marine food-fish Lophius litulon (Jordan) (Lophiiformes: Lophiidae).

Journal of food microbiology, 2018
The yellow goosefish Lophius litulon is a commercially important marine fish species. However, our present knowledge of the occurrence of nematode parasites in L. litulon remains incomplete. A total of 42 L. litulon collected from the East China Sea were

Molecular characterisation and complete mitochondrial genome of Contracaecum ovale (Linstow, 1907) (Ascaridida: Ascaridoidea) from the little grebe Tachybaptus ruficollis (Pallas) (Podicipediformes: Podicipedidae)

Journal of Helminthology
The genus Contracaecum is an important group of anisakid nematodes containing species of veterinary, medical, and economic importance. However, current genetic sequences and the mitogenomic database for Contracaecum spp. are limited. In the present study,

Polydelphis anoura Dujardin, 1845 (Nematoda: Ascaridoidea: Ascaridae) from the White-lipped Island Pitviper, Trimeresurus insularis (Ophidia: Viperidae), from Wetar Island, Indonesia

New Data on Myxobolus enoblei (Cnidaria: Myxobolidae): A Parasite of Smallmouth Buffalo Ictiobus bubalus (Cypriniformes: Catostomidae), 2019
: An imported white-lipped island pitviper, Trimeresurus insularis, originally collected from Wetar Island, Indonesia and held in quarantine and housed at the Dallas Zoo, U.S.A., unexpectedly died and was examined for gastrointestinal helminths.

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.
