Optochin sensitivity allows for the presumptive identification of alpha-hemolytic streptococci as S. pneumoniae, although some pneumococcal strains are optochin-resistant. Other alpha-hemolytic streptococcal species are optochin-resistant. Performing the optochin test Optochin (P) disks (6 mm, 5 µg) can be obtained from a commercial vendor.

However, group-level identification of alpha-hemolytic streptococci may be sufficient for clinical purposes in most cases. Since the majority of the variation between the 16S rRNA gene sequences of streptococcal species is located close to the 5′ end of the gene, the discriminatory power of the v1 and the v2 region is close to that of the full-length 16S rRNA gene sequence.

Beta-hemolytic species cause complete rupture of red blood cells. alpha-hemolysis (green) (Figure 1). The alpha-hemolytic property differentiates this organism from many species, but not from the commensal alpha-hemolytic (viridans) streptococci. Differentiating pneumococci from viridans streptococci is difficult as young pneumococcal colonies appear raised, similar to viridans streptococci. Alpha-hemolytic streptococci are known as viridians streptococci.

It is useful in the identification of Streptococcus pneumoniae, the alpha-hemolytic Streptococcus most commonly susceptible to this chemical. Other alpha-hemolytic streptococcal species are optochin-resistant. This test determines whether the bacterium is either sensitive (susceptible) to optochin or resistant to the chemical.

Alpha hemolytic species produce alpha-hemolysin which reduces hemoglobin (red) to methemoglobin (green) causing a brownish or greenish zone around the colony. Beta hemolytic species produce a hemolysin that forms a clear zone around the colony, indicating complete lysis of red blood cells.
