Whо аm I? My cоlоnies аre hockey pucks. Senior citizen colonies аre wagon wheels. I am the 3rd most common cause of middle ear infections (otitis media) in children. If you are a healthy individual, I will be in the upper respiratory tract. If you have COPD, I will be in the lower respiratory tract. I laugh at penicillin, ampicillin and amoxicillin! I produce beta-lactamase, rendering them useless. I am a normal commensal of the respiratory tract, but as most of my brothers and sisters, I am opportunistic. Who am I?
