protozoal infection by coccidia. In humans it takes the form of Isospora belli in the stools; such infection is usually asymptomatic but occasionally causes a severe watery mucous diarrhea.
Group name for diseases due to any species of coccidia; a common and serious protozoan disease of many species of domestic animals and birds and many wild animals kept in captivity; both intestinal and pulmonary coccidiosis have been reported in humans with AIDS.
coccidiosis/coc·cid·i·o·sis/ (kok-sid″e-o´sis) infection by coccidia. In humans, applied to the presence of Isospora hominis or I. belli in stools; it is often asymptomatic, rarely causing a severe watery mucous diarrhea.
A parasitic disease of many animals, including cattle, swine, sheep, dogs, cats, and poultry, but rarely of humans, resulting from infestation of the digestive tract by coccidia.
Etymology: Gk, kokkos + osis, condition
a parasitic disease of tropical and subtropical regions caused by the ingestion of oocysts of the protozoon Isospora belli or I. hominis. Symptoms include fever, malaise, abdominal discomfort, and watery diarrhea. The infection is usually self-limited, lasting 1 to 2 weeks, but occasionally it persists, resulting in malabsorption syndrome and, rarely, death. No specific therapy has been found. Compare coccidioidomycosis.
Group name for diseases attributable to any species of coccidia; a common disease of many species of domestic animals and birds; both intestinal and pulmonary coccidiosis have been reported in patients with AIDS.
coccidiosisA tropical parasitic disease caused by the accidental eating the egg cysts of the PROTOZOON Isospora belli. It features fever, abdominal pain and watery diarrhoea and usually settles in a week or two.
coccidiosisa disease caused by SPOROZOAN parasites that occurs in rabbits and poultry.
infection by coccidia causes enteritis in all species. The clinical picture varies between species. In calves it is a serious diarrhea and dysentery and death may occur because of the blood and protein loss and the dehydration. In sheep the effects are poor production and poor weight gain, although diarrhea and dysentery may occur. The clinical disease is rare in pigs and horses but outbreaks, similar clinically to those in cattle, may occur in young animals. In dogs and cats, infection is most common in young puppies and kittens where it can be the cause of severe diarrhea and even death. Adults usually experience only mild and self-limiting infections. All poultry species suffer severe outbreaks of the disease characterized by diarrhea and dysentery. Subclinical infections causing reduced productivity are a feature of the disease in birds. Affected fish are cachectic and trail long mucoid fecal casts.
The disease in all species except fish is caused by eimeria, isospora or cystoisospora. In fish the species involved is Eimeria (Epieimeria), Goussia, Cryptosporidium spp.
a small number of calves in an outbreak of classical coccidiosis may develop severe nervous signs including hyperesthesia, nystagmus, tremor, orthotonus and convulsions and die within a few hours. There is no detectable lesion in the brain.
