Gravid Angiostrongylus cantonensis can utilize radiolabelled bicarbonate, orotate, uracil, uridine and cytidine but not cytosine, thymine and thymidine for the synthesis of RNA and DNA. In cell-free extracts of the worm, a phosphoribosyltransferase was shown to convert orotate to OMP and uracil to UMP.

Filaroides hirthi sp. n. (Nematoda: Metastrongyloidea) from the Lung of the Dog
The Journal of Parasitology, 1975Filaroides hirthi sp. n. is smaller than previously described species of the genus Filaroides v. Beneden, 1858, and differs from F. milksi Whitlock, 1956, with which it is most likely to be confused, in having shorter, slightly stouter spicules with a broader proximal knob for attachment of the retractor muscles.

The unique lungworms (Nematoda: Metastrongyloidea) of the opossum (Didelphis marsupialis linnaeus)
Systematic Parasitology, 1980Prestwoodia delicata (Travassos, 1946) Anderson, 1978, Heterostrongylus heterostrongylus Travassos, 1925 and Didelphostrongylus hayesi Prestwood, 1976 are redescribed on the basis of new collections of specimens from Didelphis marsupialis from North and South America. The three genera are unique to the opossum.

1. Radioactivity was found to be associated with purine ribonucleotides in extracts of gravid adult Angiostrongylus cantonensis from the lungs of rats when the parasite was incubated in a medium containing [14C]glycine. 2. The rate of incorporation was at least 0.2 pmole/min per mg of parasite and approximately equal amounts of adenine and guanine ...

Abstract 1. 1. The pathways of purine ribonucleotide synthesis and interconversion that are operative in the gravid rat lung worm, Angiostrongylus cantonensis, were identified by radioisotope tracing in intact whole worms and by measurement of enzyme activities in cell-free extracts 2. 2.

The effect of Pneumostrongylus tenuis (Nematoda: Metastrongyloidea) on kids.
Canadian journal of comparative medicine : Revue canadienne de medecine comparee, 1970Kids, 6-28 weeks of age, infected with 200-1000 infective larvae of meningeal worm (Pneumostrongylus tenuis) of white-tailed deer (Odocoileus virginianus), developed colitis and peritonitis. Bacteroides sp., Bacillus sp., Escherichia coli, Proteus sp. and Enterococcus sp. were found in the peritoneal cavity.

Lungworms (Metastrongyloidea: Pseudaliidae) of harbor porpoise Phocoena phocoena (L. 1758)
Canadian Journal of Zoology, 1975Lungworms were collected from 60 harbor porpoises shot at sea during May to August of 1970 and 1971 in the Bay of Fundy. These have been compared with related species from other odontocetes in order to evaluate the literature on pseudaliids and provide a consistent treatment of the family.

The meningeal worm (Parelaphostrongylus tenuis) was found in 75 of 190 (39%) white-tailed deer (Odocoileus virginianus) examined in Oklahoma from 1977-81. Infections were found in deer from southeastern mixed forest, oak-hickory forest, oak-bluestem parkland and oak-hickory parkland, and not in deer from western bluestem prairie, bluestem-grama prairie

A taxanomic revision of the lungworms (Nematoda : Metastrongyloidea) from Australian marsupials
Australian Journal of Zoology Supplementary Series, 1979The taxonomic status of metastrongyloid nematodes from Australian marsupials is reviewed. Metastrongyloids are reported from 20 host species belonging to the Dasyuridae, Peramelidae, Phalangeridae, Petauridae, Macropodidae and Vombatidae. Three nematode genera in two families are recognized.

1. All major classes of lipids were found in the young adults in brain (22 days post-infection) and gravid Angiostrongylus cantonensis in lung of rats (34 days post-infection) comprising approximately 60% of phospholipids, 30% of neutral lipids and the rest, glycolipids. 2. The relative composition of phospholipids were quite similar between worms from
