Trichinella spiralis: secreted antigen of the infective L1 larva localizes to the cytoplasm and nucleoplasm of infected host cells.

Antibodies were elicited against a purified antigen with an apparent molecular weight of 43K. This antibody preparation also detected a second antigen consisting of a group of closely related components of 45-50K. These antigens are stage specific for the infective first stage larva of Trichinella spiralis and are among the repertoire of secreted antigens… (More)
