The streptococci can be antigenically classified into Lancefield's groups A through O by ________ in their cell walls
a. polyschaccaride
b. lipids
c. proteins
d. all of the above
Homework Answers
Lancefield grouping is the method of classifying the members of the Family Streptococcaceae on the basis of the carbohydrates present in the antigen on the cell wall of the bacteria. The bacteria are grouped into various groups like Group A, B, C, D etc.
So, the correct answer is a) polysaccharides which are complex carbohydrates.
