> The primary mechanisms of T. gondii–induced behavioral changes in rodents occur through epigenetic remodeling in neurons that govern the relevant behaviors (e.g. hypomethylation of arginine vasopressin-related genes in the medial amygdala, which greatly decrease predator aversion).

It's got a whole list of different things that it does. Yes, some of that could be "epigenetic tweaking a gene that looks like this" would have different effects in different species (and even different genotypes - different effects for men and women). Changing the epigenetic of the regulatory genes can do different things in different species where the regulation genes have taken on different functions.
