I wouldn't be too worried. The thing with probiotics, is humaworm will kill everything in your gut, so it's pointless to take probiotics while on humaworm because it won't benefit you.
However, I have read that parasites can feed off of probiotics, I don't know if that is true or not, but you may not want to be feeding them while you are trying to kill them, but...I don't think there is really enough probitoics in the yogurt to make a difference either way. Just my opinion.
