Lancefield classification

Lancefield classification groups Streptococcus bacteria based on specific carbohydrates found on their cell surfaces. These carbohydrate patterns serve as markers, allowing scientists to categorize different Streptococcus strains into groups labeled with letters like A, B, C, etc. This classification helps in identifying the bacteria responsible for various infections and guiding appropriate treatment. For example, Group A Streptococcus is linked to illnesses like strep throat. Overall, Lancefield grouping is a useful tool for microbiologists to organize and study Streptococcus bacteria based on their surface properties.
