Echinococcal cysts are slow growing, [3] but can cause clinical symptoms in humans and be life-threatening. [4] Cysts may not initially cause symptoms, in some cases for many years. [3] Symptoms developed depend on location of the cyst, but most occur in the liver, lungs, or both. [4]
If the cyst containing flesh of these hosts is ingested by a definitive host, such as dogs, and cats, the cysts are ingested and the larvae escape the cysts and penetrate the gastric wall. [17] These released larvae travel to the connective tissue and muscle as observed before and after 4 weeks they return to the gastric wall as adults. [17]
Dogs are ten times more likely to be infected than humans. The disease in dogs can affect the eyes, brain, lungs, skin, or bones. [15] Histoplasmosis* is a fungal disease caused by Histoplasma capsulatum that affects both dogs and humans. The disease in dogs usually affects the lungs and small intestine. [16]

In the human manifestation of the disease, E. granulosus, E. multilocularis, E. oligarthrus and E. vogeli is localized in the liver (in 75% of cases), the lungs (in 5–15% of cases), and other organs ...
The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid.

The dogs found what was ultimately determined to be a left tibia, or shinbone. Mejia said the bone was “relatively clean” in comparison to the skull they found in August. Chichareen also ...
Symptoms do not usually occur. [9] Genus Besnoitia infects cats that ingest cysts in the tissue of rodents and opossums, but usually do not cause disease. [9] Genus Sarcocystis infects carnivores that ingest cysts from various intermediate hosts. Sarcocystis may cause disease in dogs and cats. [9] Genus Toxoplasma has one important species, T ...
