Summary

Arcanobacterium haemolyticum and beta-haemolytic streptococci are significant causes of sore throats in army conscripts, often presenting with exudate and lymphadenopathy. These bacteria were more prevalent in symptomatic individuals than in healthy controls.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Public Health

Background:

  • Sore throat is a common ailment, particularly in young adults.
  • Bacterial infections, including streptococcal pharyngitis, are frequent causes of sore throat.
  • The role of Arcanobacterium haemolyticum in pharyngitis requires further elucidation.

Purpose of the Study:

  • To determine the prevalence of Arcanobacterium haemolyticum and beta-haemolytic streptococci in army conscripts with sore throat.
  • To compare clinical features between culture-positive and culture-negative patients.
  • To assess the pharyngeal colonization rates of these bacteria in healthy conscripts.

Main Methods:

  • Throat cultures were performed on 498 army conscripts presenting with sore throat.

  • Cultures were also taken from 232 healthy conscripts for colonization rate assessment.
  • Clinical data, including symptoms and physical examination findings, were collected and analyzed.

    • Main Results:

    • Arcanobacterium haemolyticum was identified in 1.4% and beta-haemolytic streptococci in 23% of symptomatic conscripts.
    • Of the beta-haemolytic streptococci, 38% were group A.
    • Culture-positive patients exhibited significantly higher rates of pharyngeal exudate, cervical lymphadenopathy, and ear ache, but less cough, compared to culture-negative patients.
    • Pharyngeal colonization rates in healthy conscripts were 0.4% for A. haemolyticum and 6.5% for beta-haemolytic streptococci.

    Conclusions:

    • Arcanobacterium haemolyticum and beta-haemolytic streptococci are important pathogens in army conscripts with sore throat.
    • Clinical presentation, including exudate and lymphadenopathy, can help differentiate bacterial pharyngitis.
    • Lower colonization rates in healthy individuals suggest these bacteria are more associated with active infection in this population.
