[Acute pharyngo-tonsillitis. Penicillin, yes or no?].

Acute tonsillitis and acute pharyngitis show a high incidence in the healthy population. Recent microbiological studies have demonstrated changes in the frequency with which different microorganisms promote such infections. This fac, together with the variations in sensibility or resistance of germs to the diverse therapeutic agents, have led to the conclusion that penicillin must not be considered as the solo drug of choice in these infections.
