L’haplodiploidie des oxyurida [PDF]

Annales de Parasitologie Humaine et Comparée, 1984
La formule chromosomique de 2 especes de Thelastomatidae (Oxyurida), Hammer-schmidtiella sp. et Thelastoma sp., parasites de Diplopode est etudiee. Dans les deux cas il y a haplodiploidie : mâle avec 4 (Thelastoma sp.) ou 5 (Hammerschmidtiella sp.) chromosomes et femelle correspondante avec le double. L’haplodiploidie est maintenant connue dans les

Higher risk of gastrointestinal parasite infection at lower elevation suggests possible constraints in the distributional niche of Alpine marmots [PDF]

, 2017
Alpine marmots Marmota marmota occupy a narrow altitudinal niche within high elevation alpine environments. For animals living at such high elevations where resources are limited, parasitism represents a potential major cost in life history.

Biological specifics of exogenous development of Oxyuris equi nematodes (Nematoda, Oxyuridae)

Biosystems Diversity, 2020
Helminths of the species Oxyuris equi Schrank, 1788 are pathogens of domestic and wild odd-toed ungulates. They parasitize in the large intestine of horses, causing colitis and dermatitis at the tail root area.

Morphological characteristic of Skrjabinema ovis (Nematoda, Oxyuridae) obtained from domestic sheep

Regulatory Mechanisms in Biosystems, 2020
Skrjabinemosis is a widely prevalent helminthiasis of sheep, goats and wild ruminants. It is caused by Skrjabinema ovis Skrjabin, 1915. Parasitization by S. ovis induces inflammatory processes of the large intestine, in skin around the anus and tail base,

Phylogeny and biogeography of species of Syphacia Seurat, 1916 (Nemata : Oxyurida : Oxyuridae) from the Australian Bioregion

Australian Journal of Zoology, 2016
Pinworm nematodes of the genus Syphacia (Nemata : Oxyurida : Oxyuridae) have a global distribution, and infect the caecum of rodents. Within the Australian Bioregion, 17 species of Syphacia infect a range of rodent hosts. Pinworms are traditionally thought to have coevolutionary relationships with their hosts, but the evolution and dispersal of ...

A Survey of Gopherus polyphemus Intestinal Parasites in South Florida

Journal of Parasitology Research, Volume 2018, Issue 1, 2018., 2018
Gopherus polyphemus populations are diminishing throughout their range due to urbanization, fragmentation, and poor habitat management. Increased population densities, poor habitat quality, and lack of fire may influence disease transmission. Parasite roles within wild tortoise populations are largely unknown; despite evidence these pathogens may pose ...

Maintaining microendemic primate species along an environmental gradient – parasites as drivers for species differentiation

Ecology and Evolution, Volume 4, Issue 24, Page 4751-4765, December 2014., 2014
Madagascar's primate species richness is unparalleled in the world due to many microendemic species with very restricted ranges. Our study of three partially sympatric species of mouse lemurs (Microcebus spp.) shows that two species can produce hybrids.

Haplodiploidy in the Oxyurida: decoupling the evolutionary processes of adaptation and speciation [PDF]

Annales de Parasitologie Humaine et Comparée, 1990
Host distribution and life history variation in the Oxyurida are discussed in the context of haplodiploidy. The Oxyurida have the broadest host distribution of any zooparasitic nematode group but have retained a virtually unchanged life cycle. Like other haplodiploids, oxyuridians have life histories that maintain viscous population structures.

Gastrointestinal Helminth Parasites Community of Fish Species in a Niger Delta Tidal Creek, Nigeria

Journal of Ecosystems, Volume 2014, Issue 1, 2014., 2014
A pool of fish species in a Niger Delta tidal creek, Buguma Creek, Nigeria, collected monthly from November 2004 to June 2006, at flood tides, were examined for gastrointestinal helminth parasites. The fish species were caught with hooks and lines and cast nets. Only nematode parasites were encountered in the study. Of the 1,149 fish specimens examined,
