Resumen
La trichinellosis es una zoonosis parasitaria que se encuentra distribuida alrededor del mundo. Es endémica en la Argentina y constituye un grave problema de salud pública, dadas las tasas altas de morbilidad que presenta. El hombre y una amplia variedad de animales se infectan al consumir carne cruda o poco cocida infectada con larvas del nematode. Hasta el momento, nueve especies y tres genotipos de Trichinella fueron descubiertos en un amplio rango de animales incluyendo mamíferos, aves y reptiles tanto en el ámbito doméstico como silvestre. En un comienzo, la trichinellosis en el hombre estaba estrechamente relacionada con el consumo de carne de cerdo doméstico; sin embargo, el descubrimiento de nuevas especies nos ha conducido a un cambio en el estudio de la epidemiologia de la enfermedad con la incorporación de nuevas fuentes de infección, como la carne proveniente de equinos, pumas, jabalíes, entre otros. El estudio de las características propias de cada especie y genotipo de Trichinella nos permite conocer aquellos puntos sobre los cuales implementar medidas de control para evitar la infección en el hombre y para minimizar la dispersión del parásito en el ambiente.
Trichinellosis is a world-wide-spread parasitic zoonosis. In Argentina it is an endemic disease representing an important risk for human health due to its high rates of morbidity. Humans and a wide variety of animals acquire the infection by eating raw or undercooked meat that contains the infective larvae of the nematode. Until now, nine species and three genotypes belonging to the genus Trichinella have been discovered in different animals, including mammals, birds and reptiles, both in domestic and sylvatic environments. At the beginning, human trichinellosis was closely related to the consumption of pork meat. Nevertheless, the discovery of new Trichinella species have led to a change in the study of the epidemiology of the disease with the addition of new sources of infection, such as the ingestion of meat from horse, cougar or wild boar. The study of the inner characteristics of each Trichinella species and genotypes will allow us to know better the critical points where some control measures can be introduced in order to prevent humans from acquiring the infection, and at the same time, to decrease the risk of dispersion of the parasite in the environment.
