Medical … Alpha-hemolytic streptococci (commonly called viridans streptococci) are surrounded by green discoloration resulting from incomplete hemolysis. Gamma-hemolytic streptococci are nonhemolytic. Subsequent classification, based on carbohydrates in the cell wall, divides streptococci into 20 Lancefield groups A through H and K through V (see table Lancefield Classification *). 2007-03-01 alpha-hemolysis (green) (Figure 1).

These are found as commensals in the upper respiratory tract of humans, and these may cause opportunistic infections. Streptococcus salivarius is an important opportunistic pathogen belonging to this group Streptococcus pneumoniae also belongs to alpha-hemolytic group). Group A beta-hemolytic streptococci (GABHS) are gram-positive bacteria that grow in culture as pairs or chains of variable length.

A total of 278 alpha- and nonhemolytic streptococcal isolates (patients, n = 116; healthy adults, n = 162) were examined for susceptibility to 23 and 24 antimicrobial drugs with the Bauer-Kirby agar disk diffusion and the agar dilution method, respectively. Wilkins-Chalgren medium compared favorably with sheep blood Mueller-Hinton agar, the reference medium, for 58 representative streptococcal isolates. Alpha-hemolytic Streptococci (incomplete hemolysis or partial hemolysis) Alpha hemolytic streptococci are gram-positive, spherical, and non-motile organisms whose cells are organized in pairs or short chains. They are facultative anaerobes and form a characteristic α-hemolytic zone on blood agar plates.
