STREPTOCOCCUS AGALACTIAE SELECTIVE AGAR BASE

Streptococcus agalactiae is a gram-positive Streptococcus characterized by the presence of group B Lancefield antigen. S. agalactiae exhibits beta haemolysic reaction. On Blood agar plate, it forms zones of haemolysis that are slightly bigger than the size of colonies formed. Group B streptococci hydrolyze sodium hippurate and give a positive response in the CAMP test. S. agalactiae is also sensitive to bile and will lyse in its presence. Streptococcus Agalactiae Selective Agar was formulated by Hauge and Kohler-Ellingsen for the isolation of S. agalactiae, the causative agent of mastitis in cattle.

for selective isolation of Streptococcus agalactiae from dairy products.
