Early recognition of the CAMP-reactivity in group B streptococci.

Abstract

Early detection of the CAMP-reactivity of group B streptococci was achieved in 5% sheep or bovine blood agar supplemented with maltose or glucose at a final concentration of 0.04% under aerobic as well as under microaerobic conditions in a candle jar. All 55 cultures of group B streptococci tested on these media yielded distinct CAMP-reactions within 8 to 10 h of incubation at 37 degrees C, allowing a more rapid recognition of these streptococci.
