Not sure about this as it's a zoonotic (i.e. crossed species boundary) infection. In its natural host I'm sure it does as you suggest - in us, it basically just goes crazy. Unlikely it evolved with us as part of the equation although that's not to suggest that something funky won't/doesn't happen when it gets into a human pool for a bit. Who really knows though? It's that bad that not enough people have studied it.
