ref anant 5th ed pg 188

DRATKINS · Credits: 8535 My Scrapbook

but, c-carbohydrate is +NT in cell wall or on cell wall, it's is in cell wall -i suppose

Anantnarayan pg 188 says'....on the cell wall'

DRATKINS · Credits: 8535 My Scrapbook

so, ans is both

aqua · Credits: 3502 My Scrapbook

yup

DRATKINS · Credits: 8535 My Scrapbook

anantnarayan says''C-CARBOHYDRATE Ag IS AN INTEGRAL PART OF CELL WALL''
it doesn't say it's on cell wall
harrison says'' C-CARBOHYDRATE CONSTITUTES MAJOR PART OF CELL WALL''

I THINK,U DECIDE ON UR OWN.

Well,I wud go for both.
BTW,Anantnarayan does say it-

'the hemolytic streptococci were classified by Lancefield serologically into groups based on the nature of a cabohydrate(C) antigen ON the cell wall.'
