Nocard and Mollereau (1 887) were the first to describe the isolation of streptococci from
bovine mastitis and these organisms were likely to have been the group-B streptococci …

This chapter reviews the genus Streptococcus including: classification, morphology, cultural
characters, metabolism, biochemical reactions, susceptibility to physical and chemical …
