stoic, laid-back, and slow-tempered. In other words, they become just the sort of guys who would be unlikely to interfere with their "cat lady" wives, to hinder them from tending to their brood of adoring felines!
Now, having outlined this array of creepy Toxoplasma effects, I need to give the following disclaimer: these effects on personality are often fairly subtle, and many infected individuals exhibit no measurable effects at all.
Nevertheless, the obvious question for each of us is: what if I'm infected, and if so, what can be done about it? I am duty-bound to urge you to consult with your physician on this one. Certainly, there are fairly straightforward blood tests that can determine whether or not you have Toxoplasma antibodies in your system (which would in turn indicate whether or not you've ever had an active infection, in which case it's likely that you would still have Toxoplasma cysts in muscle and nervous tissue).
There are a number of different antibiotics that seem to have at least some effect in combating the Toxoplasma cysts in the brain, although at this point it's premature to say that any single drug (or combination) is a guaranteed cure. Given the enormous potential public health implications of this issue - which is just now coming to widespread attention - I think it's safe to say that finding a reliable way to eradicate Toxoplasma will become a high clinical research priority in the years ahead.
