title: Pharyngitis in adults: the presence and coexistence of viruses and bacterial organisms.
abstract: OBJECTIVE
  To determine the presence and coexistence of viruses and bacterial organisms causing pharyngitis in adults.
  
  
  METHODS
  Open study using diagnostic methods, including rapid antigen-detection techniques, to test for the presence of viruses of the respiratory tract, as well as Mycoplasma pneumoniae. Chlamydia trachomatis, the Chlamydia species strain TWAR, and beta-hemolytic streptococci.
  
  
  METHODS
  Open health care.
  
  
  METHODS
  One hundred six consecutive adult patients, 15 to 65 years old, whose chief complaint was sore throat.
  
  
  RESULTS
  Of the 106 patients, beta-hemolytic streptococci were found in only 24 patients (5 patients with group A streptococci, 13 with group C, 5 with group G, and 1 with group F); M. pneumoniae was found in 10 patients, the Chlamydia species strain TWAR in 9 patients, and viruses in 27 patients. Two microbes were simultaneously isolated in 3 patients, and no microbial findings were detected in 33 patients.
  
  
  CONCLUSIONS
  Because 19 patients were infected with the Chlamydia species strain TWAR and M. pneumoniae, and 24 patients were infected with beta-hemolytic streptococci, the diagnostic procedures and therapies for adult patients with pharyngitis need to be reconsidered. The results of our study also confirm earlier suggestions that the Chlamydia species strain TWAR alone is a causative agent for pharyngitis in adults.
