The coccidia parasite is nearly impossible to completely eradicate, howeverfreezing temperatures, drought, sunlight and ammoniawill kill the parasite. Coccidia multiply best in warm, wet, dirty, overcrowded conditions and unfortunately nearly every chicken run contains trace amounts of the parasite. Can ...

Eimeroidea, Sarcocystidae) in natural populations were studied in the Lauwersmeerpolder in the northern Netherlands. This parasite needs two hosts to complete its life cycle; the common vole (Microtus arvalis) as its intermediate host and the kestrel (Falco tinnunculus...
the mucosa. As the transporting cells are known to be intraepithelial lymphocytes,65,68 a subset of T cells, it is possible that cytokine-mediated influences on the behavior of these cells, affecting subsequent parasite development should also be considered as a facet of T-cell-mediated ...
A new species of Eimeria is described from the brushtail possum (Trichosurus vulpecula). Fifty (24%) of 212 faecal samples were positive for coccidia. Spor... MG O'Callaghan,PJ O'Donoghue - 《Transactions of the Royal Society of South Australia》 被引量: 8发表: 2001年 加载更多来源...
Hiba El Hajj2, Diana Penarete-Vargas1, Sébastien Besteiro1 & Maryse Lebrun 1 Apicomplexa parasites, including Toxoplasma and Plasmodium species, possess a unique invasion mechanism that involves a tight apposition between the parasite and the host plasma membranes, called "moving junction" ...

We manipulated the chronic coccidian parasite burden of females either by initiating the acute infection phase via re-infecting them with coccidian or by temporally reducing the parasite load of coccidia. We then measured the effect of this manipulation on mate preference by presenting females with a...
Coccidia of the genus Caryospora are phylogenetically old parasites with most of the species occurring in reptiles. Among the 15 Caryospora species identified in raptors and owls, six are found exclusively in the Falconidae family (Table 14-16). Their oocysts are large and spherical to ovoid ...
