Optochin

Active

Description

Optochin (or ethylhydrocupreine) is a chemical used in cell culture techniques for the presumptive identification of Streptococcus pneumoniae, which is optochin-sensitive, from other alpha-hemolytic streptococci such as Streptococcus viridans which are resistant. A common mnemonic is "OVRPS" (Optochin - Viridans Resistant, Pneumoniae Sensitive). Or "VROPS" (Viridans Resistant [to] Optochin, Pneumoniae Sensitive) The growth of bacteria that are optochin sensitive will be inhibited around an optochin disc, while the growth of bacteria that are optochin resistant will not be affected. In vitro a solution of as little as 1:10,000,000 may be inhibitory to the pneumococcus, and 1:500,000 is bactericidal.
