The Evolution of the Ascaridoidea

Journal of Parasitology, 1962
The author rejects the generally accepted view of the terrestrial origin of the Ascaridoidea from the Rhabditoidea by way of the Oxyuroidea, in which the direct life history is regarded as the primitive pattern of transmission. He advocates instead a marine origin and argues that the lips, esophagus, and excretory system of the ascaridoids can be ...

The Morphology of Thynnascaris adunca (Rudolphi) (Nematoda, Ascaridoidea)

Zoologica Scripta, 1981
The following body parts of the fish nematode Thynnascaris adunca were studied by using SEM and TEM: anterior and posterior ends, digestive tract, particularly the oesophagus and its glandular tissue, male and female reproductive organs, excretory and nervous systems, and body wall. The ova in the uterus of a female studied by SEM were found to contain

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 ...

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 ...

Two new members in the Contracaecum osculatum complex (nematoda, ascaridoidea) from the antarctic

International Journal for Parasitology, 1994
The genetic structure of adults and larvae of Contracaecum osculatum (sensu lato) from the Antarctic is analyzed on the basis of 24 enzyme loci. Significant deviations of genotype frequencies from the Hardy-Weinberg equilibrium were found, even in samples recovered from the same host.
