Streptococci are gram-positive cocci that can be arranged in chains or pairs. They are classified based on hemolysis (alpha, beta, gamma), Lancefield grouping (A-U), and biochemical reactions. Medically important streptococci include S. pyogenes (group A), S. agalactiae (group B), S. pneumoniae, and S. viridans. S. pyogenes causes pharyngitis, impetigo, necrotizing fasciitis, and post-infection diseases like rheumatic fever. Virulence factors include M protein, lipoteichoic acid, hyaluronidase, streptolysin
