To study the pathogenesis of upper respiratory tract infections, we focused on acute tonsillitis and performed three experimental and clinical studies. From these studies, we found out that there seemed to be an intimate relationship between anatomical structure and adherence of S. pyogenes, and we confirmed that the M protein of S. pyogenes played an important role in adherence to the epithelium and the normal bacterial flora was actively involved in the body's defense against infections. We also identified that nearly half of causative bacteria in tonsillitis in Japan were the genus streptococcus, especially S. pyogenes with 23.4%. The incidence of Methicillin (DMPPC)-resistant Staphylococcus aureus (MRSA) was 27% in middle ear exudate and 14.3% in nasal discharge, but no MRSA was isolated from tonsillitis.

The prevalence of infection with methicillin-resistant Staphylococcus aureus is increasing. Methicillin-resistant Staphylococcus aureus is also being recognised as an important pathogen in head and neck infections. This review summarises studies published over the past two decades which illustrate the growing prevalence of methicillin-resistant Staphylococcus aureus, and the current therapeutic approaches to head and neck infections caused by this bacterium. These infections include sinusitis, otitis, periorbital cellulitis, cervical lymphadenitis, tonsillitis, thyroiditis, retropharyngeal abscess, and abscesses and wounds of the neck. Treatment of head and neck infections associated with methicillin-resistant Staphylococcus aureus includes drainage and debridement, as well as administration of local and systemic antimicrobials that provide coverage against these organisms and against potential aerobic and anaerobic pathogens that may be present if the infection is polymicrobial.
