| Abstract: | We studied secreted-excreted immunogens in human patients infected with Trypanosoma cruzi. A pair of 45- to 55-kDa antigens and a family of shed acute-phase antigens characterized the acute phase, while antibodies against a 160- to 170-kDa immunogen appeared at the chronic phase of the disease. |
