The predominant bacteria in throat swabs have shifted from Klebsiella pneumoniae and Escherichia coli to Staphylococcus aureus and Pseudomonas aeruginosa over 12 years. This change aligns with sepsis and meningitis pathogens, with S. aureus showing reduced susceptibility to certain antibiotics.

Area of Science:

  • Clinical Microbiology
  • Infectious Diseases
  • Antimicrobial Resistance

Background:

  • Throat swabs are a common source for culturing organisms.
  • Changes in microbial flora can impact patient health and treatment outcomes.
  • Sepsis and meningitis are serious infections often linked to bacterial pathogens.

Purpose of the Study:

  • To review organisms cultured from throat swabs.
  • To identify shifts in predominant bacterial isolates over a 12-year period.
  • To correlate throat swab findings with infectious agents causing sepsis and/or meningitis.

Main Methods:

  • Retrospective review of bacterial cultures from throat swabs.
  • Analysis of predominant isolates over a 12-year period.
  • Comparison of throat swab flora with pathogens causing sepsis and/or meningitis.

Main Results:

  • Klebsiella pneumoniae and Escherichia coli were replaced by Staphylococcus aureus and Pseudomonas aeruginosa as predominant throat swab isolates.
  • The observed changes in throat swab flora were consistent with etiological patterns of sepsis and meningitis.
  • Staphylococcus aureus isolates demonstrated decreased susceptibility to cloxacillin, cephazolin, and cefotaxime since 1978.

Conclusions:

  • There has been a significant shift in the predominant bacterial organisms found in throat swabs.
  • This shift has implications for understanding and treating sepsis and meningitis.
  • Emerging antimicrobial resistance in Staphylococcus aureus warrants attention.
