Rheumatic fever can be caused by an infection with which organism?

Explanation:
Rheumatic fever follows an infection with group A beta-hemolytic streptococcus. The illness arises from an autoimmune response in which antibodies formed against the streptococcal M protein cross-react with heart, joint, and nervous tissues, causing inflammatory damage after strep throat or skin infection. This immune-mediated mechanism makes beta-hemolytic streptococci the correct organism. Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa can cause other infections but are not linked to the post-streptococcal autoimmune process that leads to rheumatic fever.
