First of all, this is a really neat primer into parasites & behavioural modifications. I have now a bunch of new interesting articles to read :D
The second thing I came to mention was my own article about parasites, which may interest you. I wrote about toxoplasma and its effect on wild hyaenas. The researchers found a staggering difference on the causes of death between hyaenas that were infected as cubs and those who weren't (100% versus 17%).
