[Current aspects of trichinosis diagnosis].

An important approach to the study of trichinellosis is the development of sensitive diagnostic methods that allow the detection of Trichinella spiralis. Recently, ELISA assays that use surface/stichosome and/or secretion/excretion antigens from muscle larvae have been proved to be highly sensitive and specific in the diagnosis of the infection. Furthermore, the high immunodominance of carbohydrate residues on these molecules in a broad host range make them useful diagnostic markers for trichinellosis.
