My child tested negative to cloatridiA (she's always possitive)and all we did was have her on bactrim and minocycline. I don't think these antibiotics kill cloatridia, So I'm thinking that perhaps the cloatridiA went away since we are treating Lyme and Bart. Could this be a possibility??? What else could have made cloatridiA go away? She wasn't on any probiotics either. I must add, that now her yeast is a problem!
