Reproductive Morphometric Plasticity in Gregarina polymorpha Infecting Tenebrio molitor Larvae

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Morphological variability remains one of the principal challenges in the taxonomy and species delimitation of gregarines (Apicomplexa: Gregarinomorphea). In the present study, we investigated morphometric variability in gametocysts and syzygies of Gregarina polymorpha infecting Tenebrio molitor larvae through quantitative morphometric and ...

Evaluation of the detection method by a flotation method using a wire loop for gastrointestinal parasites

Veterinary Medicine and Science
Infections by gastrointestinal parasites are found in a variety of animals worldwide. For the diagnosis of such infections, the flotation method is commonly used to detect parasitic microorganisms, such as oocysts or eggs, in feces.

Development of Cystoisospora felis in Cell Culture and in vitro Formation of Monozoic Tissue Cysts

Frontiers in Veterinary Science, 2019
Cystoisospora felis is a coccidian parasite commonly found in feces of domestic cats. Infection in cats occurs by ingestion of sporulated oocysts or consumption of rodents infected by the parasite.

The Effect of Heating against Cryptosporidium Oocysts.

Journal of Veterinary Medical Science, 2002
The effect of heat treatment was examined against oocysts of Cryptosporidium parvum, Cryptosporidium muris and chicken Cryptosporidium sp. isolated in Japan. The oocysts of these species were exposed at 50, 55, 60 and 70 degrees C for 5, 15, 30 and 60 sec in water bath, respectively. To determine the infectivity of heated oocysts, the nice and chickens

Characterization of a novel murine model of Toxoplasma gondii infection using oocysts of a recently obtained Type III isolate

Veterinary Research
Type II reference isolates of Toxoplasma gondii are widely used in animal toxoplasmosis models, but studies with Type III isolates remain scarce. In addition, these methods often rely on laboratory-adapted parasite stages that may not reflect natural ...

The relevance and applicability of oocyst prevalence as a read-out for mosquito feeding assays. [PDF]

, 2013
Mosquito feeding assays are important in evaluations of malaria transmission-reducing interventions. The proportion of mosquitoes with midgut oocysts is commonly used as an outcome measure, but in natural low intensity infections the effect of oocyst non-

Evidence for a Structural Role for Acid-Fast Lipids in Oocyst Walls of Cryptosporidium, Toxoplasma, and Eimeria

mBio, 2013
Coccidia are protozoan parasites that cause significant human disease and are of major agricultural importance. Cryptosporidium spp. cause diarrhea in humans and animals, while Toxoplasma causes disseminated infections in fetuses and untreated AIDS ...
