Evolution of malarial virulance

Posted by Karthikg on 02 Aug 2012 at 09:07 GMT

Excellent Manuscript, just a few quick questions,

1) is this something that is peculiar with P.chabaudi, how would other virulant strains evolve..P.yeolii, P.berghei etc

2) I think that the caveat section is very intrestiong, I am not sure how good is the translatability to human situations is, if in the mouse model infection is for 7 days before the host immune system has had a go at it...

3) if the candidate sequence remains unchanged, could some kind of an epigenetic phenomenon throw light on what is happening in the evolved parasites

Keep up the good work
