Coccidia can infect all mammals, some birds, some fish, some reptiles, and some amphibians. Most species of coccidia are species-specific in their host. An exception is Toxoplasma gondii, which can infect all mammals, although it can only undergo sexual reproduction in cats. Depending on the species of coccidia, infection can cause fever ...
Puppies are frequently infected with coccidia from the feces of their mother, and are more likely to develop coccidiosis due to their undeveloped immune systems. Stress can trigger symptoms in susceptible animals. [3] Symptoms in young dogs include diarrhea with mucus and blood, poor appetite, vomiting, and dehydration. Untreated, the disease ...
In 1896, Gilchrist and Rixford named the organism Coccidioides ("resembling Coccidia") immitis (Latin for “harsh,” describing the clinical course). Ophüls and Moffitt proved that C. immitis was a fungus rather than a protozoan in 1900.
Coccidioidomycosis (/ k ɒ k ˌ s ɪ d i ɔɪ d oʊ m aɪ ˈ k oʊ s ɪ s /, kok-SID-ee-oy-doh-my-KOH-sis) is a mammalian fungal disease caused by Coccidioides immitis or Coccidioides posadasii. [3]
The class was defined in 1988 by Levine [1] and contains two subclasses – the coccidia and the gregarines. All members of this class have a complete, hollow, truncated conoid. Gregarines tend to parasitize invertebrates with the mature gamonts being extracellular; the coccidia mostly infect vertebrates and have intracellular gamonts.
Cyclospora are eukaryotes in the phylum Apicomplexa. [3] Within the Apicomplexa, Cyclospora belong to the sub-class Coccidia and family Eimeriidae. Taxonomy of the coccidia is based upon morphological descriptions of observed parasites, and therefore does not always reflect evolutionary relationships. [3]

The taxonomy of this group is complex and only partly understood. Two major clades have been identified: the isosporoid coccidia (Toxoplasma, Neospora, Isospora [in part], and Sarcocystis) and a second clade containing Lankesterella, Caryospora and the eimeriid coccidia (Cyclospora, Isospora [in part] and Eimeria).
