Streptococci are facultatively anaerobic, catalase-negative, gram-positive cocci that occur as pairs or chains. They cause a wide variety of clinical diseases including pharyngitis, scarlet fever, otitis media, impetigo, meningitis, neonatal sepis, pneumonia, endocarditis, osteomyelitis, and necrotizing fascitis. One of the most useful phenotypic characteristics of streptococci is the hemolytic reaction, generally classified as alpha, beta or gamma according to the appearance of zones around colonies growing on Blood Agar. Beta-hemolytic streptococci are further characterized by Lancefield groups based on the antigenic differences in group-specific polysaccharides located in the bacterial cell wall.
