COCCIDIA OF ALEUTIAN CANADA GEESE
Journal of Wildlife Diseases, 1981Fecal samples from 122 captive and 130 free-ranging Aleutian Canada geese (Branta canadensis leucopareia) were examined for oocysts of coccidia. Free-ranging geese sampled on the spring staging ground near Crescent City, California were infected with Eimeria hermani, E. truncata, E. magnalabia, E. fulva, E. clarkei and Tyzzeria parvula.

Veterinary Parasitology, 1991
Faecal samples from goats were collected per rectum from February 1989 to January 1990. The numbers of oocysts per gram (OPG) of faeces were determined by the McMaster technique and identification of oocysts was made on sporulation. Infection was seen throughout the year, infecting on average 89.9% of 1092 adults and 94.0% of 151 kids. OPG of less than

The Freeze Preservation of Coccidia
Research in Veterinary Science, 1968Summary In quantitative studies on the recovery of coccidia after freezing to — 196°C., glycerol protected sporozoites of E. acervulina, E. tenella and E. maxima. Glycerol and dimethyl sulphoxide both protected sporocysts, but longer equilibration times were required.

Mysteries of host switching: Diversification and host specificity in rodent-coccidia associations.
Molecular Phylogenetics and Evolution, 2018Recent studies show that host switching is much more frequent than originally believed and constitutes an important driver in evolution of host-parasite associations.

CD8+ T cell-coccidia interactions
Parasitology Today, 1994Host responses to coccidian parasites involve many facets of the immune system, including antigen-specific as well as antigen-nonspecific components. Hyun Lillehoj and James Trout here review the evidence that cell-mediated responses are probably the main line of defense against coccidial infection.

Cerococcus catenarius Coccidia
2019Cerococcus catenarius: Coccidia is similar to the previous species, but have a hemispherical, less convex and smoother carapace.The lay is made under the carapace, from where the nymphs hatch forming lines; hence the name ‘catenarius'. These nymphs are fixed in the carapace cracks.

Publisher Summary This chapter discusses the biology of fish coccidia. The oocyst and, particularly, the structure of its contained sporocysts, are important features in differentiating the genera and species of coccidia in fishes. Except for three genera, Cryptosporidium, Octosporella, and Isospora, the fish coccidia have oocysts containing four ...

Host specificity of avian coccidia
Parasitology Today, 1986The term 'species specific' in reference to the host specificity of avian coccidia, has been used rather loosely for many years. A strong belief in strict species specificity has led to many new species of coccidia being described from oocysts isolated from the faeces of wild birds, primarily on the grounds that no coccidium had previously been ...
