Coccidiosis

While coccidia can infect a wide variety of animals, including humans, birds, and livestock, they are usually species-specific.

Other than T. gondii, the infectious organisms are canine and feline-specific and are not contagious to humans, unlike the zoonotic diseases.

[citation needed] 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.

[3] Symptoms in young dogs include diarrhea with mucus and blood, poor appetite, vomiting, and dehydration.

[citation needed] Coccidiosis (in cattle also known as Eimeriosis) is one of the most important diseases in calves and youngstock both under housing conditions and when grazing.

[11][12] Depending on the pathogen and the condition of the animal, untreated coccidiosis may clear of its own accord, or become severe and damaging, and sometimes cause death.
