Trichinellosis is a zoonotic disease that has been studied mainly in domestic pigs (Sus scrofa domesticus). The cycle involves infection in domestic and wild fauna, which fulfill complex ecological roles, where Trichinella spiralis is reported in wild boar (Sus scrofa). The objective of this study was to determine the prevalence of trichinellosis in wild boar and evaluate the distance of positive animals to the nearest urbanization areas in Argentina Patagonia.

In Argentina there is little information about diseases that affect exotic ungulates and the health risks that they pose to native wildlife, livestock, and humans. The aim of this study was to evaluate the health status of red deer ( Cervus elaphus) in the Nahuel Huapi National Park and surrounding areas in Patagonia, Argentina. During three consecutive hunting seasons, necropsies were performed on 101 red deer, and tissues were examined histologically.

Article Synopsis
  • Sarcocystis spp. are protozoan parasites that develop cysts in the muscles of herbivorous animals, often causing asymptomatic infections, with seven species identified in red deer.
  • This study aimed to assess the prevalence of sarcocystosis and analyze the characteristics of Sarcocystis spp. in wild red deer from Nahuel Huapi National Park in Argentina, involving necropsies and various laboratory techniques.
  • Results showed a 62% prevalence of infection in heart samples and highlighted that the red deer are frequently infected with Sarcocystis taeniata, although the definitive host for this parasite is still unidentified, indicating the need for further research on this infection’s epidemiology.
