From: Infectious Diseases of the Fetus and Newborn (Seventh Edition), 2011 Alpha Hemolytic Streptococcus Viridans streptococci are a heterogeneous group of α-hemolytic and nonhemolytic streptococci that are constituents of the normal flora of the respiratory and gastrointestinal tracts of infants, children, and adults.
