| coccidioidomycosis | <chest medicine, microbiology> A fungal infection caused by the fungus Coccidioides immitis. Exists in two forms: primary disease, which is a self-limited respiratory infection (requires no treatment) and a progressive form (diffuse and granulomatous), that can involve almost any part of the body. Approximately 60% of infections cause no symptoms and are identified only by skin testing. Immunocompromised patients (AIDS) are at greatest risk for disseminated disease. Symptoms include cough, anorexia, fever, weight loss and joint pains. Complications include pleural effusion and dissemination. There is a poor prognosis for disseminated disease. Treatment includes amphotericin B for lung infection. Itraconazole and fluconazole are also useful agents. (27 Sep 1997) |

| coccidiosis | Protozoan infection found in animals and man. It is caused by several different genera of coccidia. (12 Dec 1998) |

| coccidium | Common name given to protozoan parasites (order Eucoccidiida) in which schizogony occurs within epithelial cells, generally in the intestine, but in some species in the bile ducts and kidney; the final product of sexual fusion and differentiation that occurs within the host, the oocyst, generally passes to the soil in the faeces, undergoes sporulation, and then acts as the infective form for another host. Coccidia are parasitic in most domestic and wild birds and mammals, occasionally in man, and are highly host-specific; the majority are nonpathogenic, but certain species rank among the most serious and economically important pathogens, causing coccidiosis in birds and mammals.
