Bacillophobia: An abnormal and persistent fear of bacilli (bacteria). A phobia is an unreasonable sort of fear that can cause avoidance and panic. Phobias are a relatively common type of anxiety disorder. Phobias can be treated with cognitive behavioral therapy using exposure and fear reduction techniques. In many cases, anti- anxiety or anti-depressant medication proves helpful, especially during the early stages of therapy.
Another term for bacillophobia is bacteriaphobia.
