I haven't heard much about allergies to bacteria, themselves;
although many people are allergic to their by- products (eg
penicillin, tetnus, botulism).
many people also have found they have trouble balancing the biotics
in their gut- yeast versus bacteria. A place to start learning about
the balance is at http://www.panix.com/~candida/
