Rapid differentiation of streptococci isolated from cows with mastitis

The demonstration of some species-specific streptococcal enzymes with 4-methylumbelliferyl-conjugated beta-D-glucuronide, N-acetyl-beta-D-glucosaminide, and beta-D-mannoside and agglutination with the lectin from Dolichos biflorus allowed rapid tentative identification of streptococci isolated from cows with mastitis.
