Trichinellosis is a worldwide serious disease transmittable from animals to humans. The disease agent is Trichinella spp., which belongs to the phylum of parasitic nematoda called Nematodes. There are 12 genotypes of Trichinella currently known but the most important for the Czech Republic and neighboring countries are T. spiralis, T. britovi and T. pseudospiralis. Man can be infected by ingestion of raw or undercooked meat of infected animals. Treatment is very expensive and can be fatal, therefore a great emphasis is placed on prevention, especially control of animal carcasses which are intended for human consumption. The most famous method, also approved by law, is the digestive method, however there are many other methods for testing the presence of a parasite or for specification of genotype. This paper mainly deals with comparison of known and available methods of detection of trichinosis originators. Furthermore this paper gives character description of majorgenotypes of Trichinella.
