Archived sera (collected in 1946) from acute rheumatic fever (ARF)
and untreated scarlet fever and/or pharyngitis patients were
reacted with streptococcal M protein, cardiac myosin, and cardiac
tropomyosin. Except for very low levels to tropomyosin, antibodies to
other antigens were not elevated in the sera of ARF patients relative
to those of non-ARF patients, even though there was roughly equivalent
exposure to group A streptococci. This suggests that antibodies to
these molecules may not play a central role in the induction of ARF.
