Otitis Media Is Commonly Treated with Broad Spectrum Antibiotics, Although

Otitis media is commonly treated with broad spectrum antibiotics, although there is a lot of push- back or pressure against doing this. Why are these drugs given for this condition?

A) No other kinds of drugs and antibiotics can kill the bacteria causing otitis media other than the broad-spectrum class of drugs.
B) The narrow-spectrum drugs are very toxic as opposed to the rather benign broad- spectrum ones.
C) Otitis media is often caused by a variety of bacteria growing together in a biofilm, and the bacteria often exhibit different susceptibilities to drugs.
D) Fungi are the most common cause of otitis media, and the fungi do not respond well to the narrow-spectrum drugs.
