Infestation, histology, and molecular confirmation of Sarcoptes scabiei in an Andean porcupine (Coendou quichua) from the Central Andes of Colombia.

Sarcoptic mange is a highly contagious, worldwide disease that affects the skin of mammals, including humans. It is caused by the mite Sarcoptes scabiei, however, the information available in wild mammal populations in the world, and particularly in Colombia is limited. Here, we document a new case of sarcoptic mange in an Andean porcupine (Coendou quichua) from the Andean region of Colombia. We morphologically and molecularly confirmed the mite as S. scabiei and documented the histopathology associated with scabies, and show the different stages of the life cycle of S. scabiei from the Andean porcupine skin samples. Our review of reports of additional cases of scabies in wild mammal species in South America showed 15 species, mostly carnivores, artiodactyls, and rodents. Considering the limited information in Colombia, it is urgent to evaluate the risk of this condition on mammals which would contribute to the epidemiological knowledge and the potential implications of sarcoptic mange in the ecology and conservation of wild mammals in the country.
