Here, the antigenicity of the streptococcal collagen-like (CL) proteins, Scl1 and Scl2, that exhibit structural similarity to human collagen, was analyzed. Antibodies to Scl1.1 protein were detected in human sera from healthy individuals previously infected with M1 GAS and from patients with various GAS infections, as well as in sera from mice infected with M1 GAS. Linear B-cell epitope mapping identified immunoreactive peptides corresponding to the CL region of Scl1.1. Humoral responses to Scl1.28 and Scl2.28 were also detected in pediatric patients and mice infected with M28 GAS.
