Mechanics of the Toxoplasma gondii oocyst wall
The ability of microorganisms to survive under extreme conditions is closely related to the physicochemical properties of their wall. In the ubiquitous protozoan parasite Toxoplasma gondii, the oocyst stage possesses a bilayered wall that protects the ...

Structure, composition, and roles of the Toxoplasma gondii oocyst and sporocyst walls [PDF]
Toxoplasma gondii is a coccidian parasite with the cat as its definitive host but any warm-blooded animal, including humans, may act as intermediate hosts. It has a worldwide distribution where it may cause acute and chronic toxoplasmosis.

CryptosporidiumOocyst Surface Macromolecules Significantly Hinder Oocyst Attachment
Environmental Science & Technology, 2006The role Cryptosporidium parvum oocyst surface macromolecules play in controlling oocyst adhesion (deposition) kinetics to quartz surfaces has been investigated utilizing a radial stagnation point flow system. Deposition kinetics and corresponding attachment efficiencies of viable oocysts were compared with those after treatment with a digestive enzyme

Sporogony of the Oocysts of Isospora canis
Transactions of the American Microscopical Society, 1976LEPP, D. L. & TODD, K. S., JR. 1976. Sporogony of the oocysts of Isospora canis. Trans. Amer. Micros. Soc., 95: 98-103. The sporulation process of Isospora canis oocysts is described and compared with sporogony of other Isospora species of carnivores. Oocysts had not completed sporulation after 16 days at 10 C.

Toxoplasma gondii oocysts are highly resistant to environmental influences. To study the effect of alpha-irradiation on the viability of T. gondii oocysts, 1 million sporulated oocysts of the VEG strain were irradiated to absorbed doses of 0.10, 0.15, 0.20, 0.25, 0.30, 0.40, or 0.50 kGy at 5 C with a 137Cs gamma-irradiation source. Treated oocysts were

Abstract Objective—To estimate the analytic sensitivity of microscopic detection of Toxoplasma gondii oocysts and the environmental loading of T gondii oocysts on the basis of prevalence of shedding by owned and unowned cats. Design—Cross-sectional survey. Sample Population—326 fecal samples from cats.

The Size of the Oocysts of Eimeria labbeana
The Journal of Parasitology, 1959Size and shape are the features of oocysts most often described, and variation in size during the course of infection has been noted by several authors. Fish (1931), working with Eimeria tenella, and Becker, Zimmermann, and Pattillo (1955), working with E.
