Article Synopsis
  • An outbreak of mange caused by Psoroptes sp. was identified in a llama herd in Jujuy province, Argentina, with symptoms including hair loss, skin inflammation, and ear drainage.
  • Microscopic analysis confirmed the presence of Psoroptes mites, and histological studies indicated an allergic reaction with mixed inflammatory cells.
  • The research also revealed genetic links between local llama infections and similar infections in rabbits and bighorn sheep, emphasizing the need for further studies to manage these parasitic issues in South American camelids.

Vicuñas (Vicugna vicugna) are wild South American camelids (SACs) protected by law in Argentina, and information on pathogens that infect them is scarce. In this study, an adult vicuña found dead in the province of Salta was examined, and evidence of infection by Sarcocystis sp. protozoans was sought.

Free-ranging vicuñas (Vicugna vicugna) are handled in some areas of the Andean high plateau region following an ancestral practice known as chaku, which consists in their transient capture and shearing of their fiber for commercialization. In this study, 807 vicuñas captured during 12 chaku events that took place in 2019 in the province of Jujuy, Argentina, were examined for typical mange skin lesions. Twenty-eight of the examined vicuñas presented alopecia with erythema, exudation, hyperkeratosis, and/or bleeding scarred lesions, mostly in the chest, rear and front legs, and inguinal zone.
