Streptococcus agalactiae cause mastitis in cattle and some other ruminants. We have included new colony images of S. agalactiae on VetBact. The bacteria have been cultivated on bovine blood agar, a SELMA-plate and purple agar (with lactose). We have also included a picture of the result from a CAMP test of S. agalactiae and S. uberis against Staphylococcus aureus.
Anna Eriksson (SVA) has prepared the SELMA plate and Lise-Lotte Fernström (BVF, SLU) the other agar plates and the CAMP test.
