Presentation transcript:

Streptococcus pneumoniae—Gram stain. Arrows point to typical gram-positive diplococci. Note that the clear area around the organism is the capsule

Optochin test—Arrow points to zone of inhibition of growth of Streptococcus pneumoniae caused by optochin that has diffused from the disk labeled P. In the lower half of the blood agar plate, there is -hemolysis caused by Str. pneumoniae, except in the region around the optochin disk. The arrow points to the outer limit of the zone of inhibition. Upper half of blood agar plate shows -hemolysis caused by a viridans streptococcus and there is no zone of inhibition around the optochin disk
