Abstract: Disclosed are neoglycoconjugates and/or glycosides containing glycan selected from Galp?1,3Galf?, Galp?1,6Galp?1,3Galf?, or Galp?1,3Galf?1,3Manp?. Methods of using the glycosides and/or neoglycoconjugates as diagnostic or prognostic biomarkers, vaccines, treating or detecting parasitic diseases, such as cutaneous leishmaniasis are disclosed.

Abstract: Certain embodiments are directed to method for synthesizing and using glycoconjugates based on the immunodominant epitope Gal?(1,3)Gal?(1,4)GlcNAc? (Gal?3LN?).

Abstract: Use of synthetic peptides derived from Trypanosoma cruzi antigens and their use in vaccination against trypomastigote infection and Chagas disease. T. cruzi uses several surface proteins to invade the host. In their role of protection, the surface protients ensure the targeting and invasion of specific cells or tissues. A conserved region in the family of mucin-associated surface proteins (MASP) was used to analyze the expression of MASP at different points of invasion and proved to be important for host cell invasion, thus suggesting MASP as a candidate for vaccine development. A synthetic peptide, MASPsyn, was studied and showed efficacy in stimulating antibody and cytokine production necessary for resistance against the parasite.

Abstract: A chemiluminescent (CL)-ELISA method with purified and complex antigens of Trypanosoma cruzi is proposed for the specific and sensitive diagnosis of Chagas' disease in patients and blood bank samples. A trypomastigote specific antigen (A&T) together with an epimastigote extract (EpEx), used as a control of sensitivity, are the preparations used. The high sensitivity of the CL-ELISA method permits the use of extremely small amounts of antigen and allows a serum dilution in routine tests as high as 1:2000, thus reducing the nonspecific or false-positive reactions to a minimum. The use of the A&T purified antigen eliminates cross-reactivities with other infectious agents, detects active infection, and serves to monitor chemotherapy in chronic patients. The use of the EpEx antigenic preparation not only confirms the positive results with A&T but also, in case of discrepancy, suggests other infections such as leishmaniasis.
