E) Polysaccharide capsule
. but is it only the capsule that is virulent? this also seems to be a famous question innit? ive come across the India Ink c.neoformans quite a few times. symptoms can be diff, but the India Ink is always mentioned. do u think its possible to ask the question of c.neoformans without India Ink as a clue?
