Ascaridoid nematodes of amphibians and reptiles: Dujardinascaris
From the known species occurring in crocodilians, the genus Dujardinascaris is redefined and found to be a homogenous group of species, with dujardini Travassos, 1920 as the type species. TheExpand
Ascaridoid nematodes of amphibians and reptiles: Polydelphis, Travassosascaris n.g. and Hexametra
TLDR
The ascaridoid nematodes with more than two uterine branches, which occur in snakes and lizards, are grouped into three genera: Polydelphis, Travassosascaris and Hexametra. Expand
The life history and development of Toxocara cati (Schrank 1788) in the domestic cat.

  • Biology, Medicine
  • Parasitology
  • 1 May 1956
TLDR
The evidence from experimental and natural infection indicated that infection of cats with T. cati always takes place after birth, and no larvae were found in the alimentary tract of dogs following experimental infection either with eggs or with infected mice. Expand
Ascaridoid nematodes of amphibians and reptiles: Multicaecum and Brevimulticaecum.
  • J. Sprent
  • Biology, Medicine
  • Journal of helminthology
  • 1 March 1979
TLDR
The genus Multicaecum Baylis 1923, sensu Hartwich 1957, was found to be heterogeneous, comprising species which are released to two distinct genera, namely Multicasecum Bavlis, 1923 and Brevimulticaecu, 1923, which are discussed in relation to the other genera of ascaridoid nematodes in crocodilians.

Notes on Ascaris and Toxascaris, with a definition of Baylisascaris gen.nov.
  • J. Sprent
  • Biology, Medicine
  • Parasitology
  • 1 February 1968
The family Ascarididae, as defined by Hartwich (1957) and emended by Osche (1958), comprises species in the genera Ascaris, Toxascaris, Parascaris and Lagochilascaris , all occurring in terrestrialExpand
Observations on the development of Toxocara canis (Werner, 1782) in the dog.
  • J. Sprent
  • Biology, Medicine
  • Parasitology
  • 1 May 1958
TLDR
Differences in migratory behaviour are adaptations to prevailing modes of nutrition and it is suggested that the somatic migration occurring in dogs is an adaptation to the non-predatory habits of this particular host. Expand
Ascaridoid nematodes of amphibians and reptiles: Gedoelstascaris n.g. and Ortleppascaris n.g.
  • J. Sprent
  • Biology, Medicine
  • Journal of helminthology
  • 1 September 1978
Two new genera, Gedoelstascaris and Orleppascaris, are proposed for species of ascaridoid nematodes occurring in crocodilians and previously included in Dujardinascaris. Species included inExpand
Ascaridoid nematodes of Sirenians—the Heterocheilinae redefined
TLDR
The suggestion is made that the ascaridoids of sirenians originated from forms in fluviatile lower vertebrates. Expand
Ascaridoid nematodes of amphibians and reptiles: Ophidascaris Baylis, 1920
  • J. Sprent
  • Biology
  • Systematic Parasitology
  • 1 May 1988
TLDR
The genus Ophidascaris is revised and divided into five groups of species and a key is provided for differentiating eight species based on fresh and preserved specimens and on developmental patterns. Expand
