Lamanema chavezi and Sarcocystis spp. are parasites of camelids within South America that are commonly identified as incidental findings on necropsy. Lamanema chavezi is a nematode that causes significant hepatic damage as well as intestinal and pulmonary damage due to migrating larvae. Tuis (young alpacas) can succumb to acute disease, or lesions indicative of previous infection may be found in older animals. Sarcocystis spp are protozoons with a two host life cycle, in this case involving the camelid and the dog. They encyst in the muscles of the camelid, occasionally causing enough muscle damage to produce acute disease. However, the major damage this parasite inflicts is through losses due to contaminated meat. Both of these parasites are present in the majority of alpacas within South America; however they are found rarely if at all in the rest of the world.
