optochin susceptibility test

optochin susceptibility test
(for differentiation of pneumococci from other streptococci) an SBA plate is inoculated with a sample of α-hemolytic streptococci, and a filter paper disk containing optochin is added to the surface of the plate, which is then incubated overnight. The size of the observed zone of inhibition determines whether Streptococcus pneumoniae is present.
