Human trichinellosis is a worldwide zoonosis caused by different species of Trichinella, which can survive and adapt to the environmental conditions. Over the last decades molecular biology breakthrough allows the identification of encapsulated and non-encapsulated clades on all continents. The following species and genotypes: T. spiralis, T. nativa, T. nelsoni, T. britovi, T. murrelli, T. patagoniensis, T. chanchalensis (the last species found in Canada, in Gulo gulo), T6, T8 and T9 belongs to the encapsulated clade while T. pseudospiralis, T. papuae and T. zimbabwensis belong to the non encapsulated clade. In America and other continents, Trichinella infection is a health issue for people, which has a negative impact on meat markets. Trichinellosis is endemic in Argentina and during the 2019-2021 period, there were 1532 human cases. Carnivores act as concentrators and contribute to the maintenance of the parasite in nature. In pigs, the establishment of larvae, generate important disturbances and pathological changes in skeletal muscles and organs. Wild boars (Sus scrofa) are excellent hosts for the genus Trichinella and, as occurs in pigs, symptoms are scarce. Horses and herbivores can acquire Trichinella spp. through occasional consumption of infected meat. It is important to consider that all domestic and wild animals destined for consumption must be analyzed to avoid the disease in man. Fil: Pasqualetti, M.I. Universidad de Buenos Aires.
