Pigs are a major reservoir of the parasite, and infection of humans occurs more frequently in areas where pigs comingle with people. This includes places like the Philippines, as previously mentioned, but also includes countries such as Bolivia and Papua New Guinea. But pigs are not the only animal where the parasite is found. For example, Balantidium coli also has a high rate of incidence in rats. In a Japanese study that analyzed the fecal samples in 56 mammalian species, Balantidium coli was found to be present not just in all the wild boars tested (with wild boars and pigs being considered the same species), it was also found in five species of non human primate: Chimpanzee (Pan troglodytes), White-handed gibbon (Hylobates lar), Squirrelmonkey (Saimiri sciurea), Sacred baboon (Comopithecus hamadryas), and Japanese macaque (Macaca fuscata). In other studies, Balantidium coli was also found in species from the orders Rodentia and Carnivora. References

Tuberculoid leprosy is a form of leprosy characterized by solitary skin lesions that are asymmetrically distributed with few lesions and well demarcated edges. There is also early and marked nerve damage. It tends to heal spontaneously. : 345  Tuberculoid leprosy is characterized by the formation of epithelioid cell granulomas with a large number of epithelioid cells. In this form of leprosy Mycobacterium leprae are either absent from the lesion or occur in very small numbers. This type of leprosy is the most benign and the least contagious. See also
