Cloning and characterization of a gene encoding a novel immunodominant antigen of Trypanosoma cruzi.

abstract：:One of the candidate schistosome antigens for the development of a circulating antigen detection diagnostic assay is the circulating cathodic antigen (CCA). Detection of CCA in urine provides a non-invasive assay with high sensitivity. Previously we reported that CCA is secreted in patients' urine as a small molecular...
