B.<unk>  is found abundantly in its definitive host, the giant panda. Similar roundworms from<unk>  genus have been found to infect up to 90 other wild and domestic animal species. Very little research has been done on the potential of human infection with this roundworm, but the possibility is still taken with precautions when handling the pandas and fecal samples. Many of these animals act as paratenic hosts and the infection results in the penetration of the gut wall by the larvae and subsequent invasion of tissue, resulting in severe disease. In animals, it is the most common cause of larva migrans. The paratenic host, however, cannot shed infective eggs, as the larva will not complete its life cycle until it makes its way into a panda. In pandas, there are no confirmed paratenic hosts for this roundworm and it has never been found in humans.
