Chronic sinusitis (CR) involves mostly aerobic bacteria with serious antibiotic resistance. While bacterial infection isn't the main cause, susceptibility testing is crucial before antibiotic use.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Otolaryngology

Context:

  • Chronic sinusitis (CR) is a prevalent condition often associated with bacterial infections.
  • Understanding the microbial landscape and antibiotic susceptibility patterns in CR is essential for effective treatment.

Purpose:

  • To characterize bacterial isolates from patients with chronic sinusitis (CR).
  • To investigate antibiotic resistance patterns, including beta-lactamase-producing bacteria (beta-LPB), in CR pathogens.
  • To compare bacterial distribution in CR patients versus healthy controls.

Summary:

  • Twenty bacterial species were identified in CR patients, with aerobes being predominant (83.4%).
  • Significant antibiotic resistance was observed; Imipenem, Cefotaxime, and Amoxicillin-clavulanate showed good in vitro activity against aerobic pathogens.

  • Beta-lactamase-producing bacteria (beta-LPB) were detected in 37.7% of strains. No significant difference in bacterial distribution was found between CR patients and healthy controls.

    • Impact:

    • Highlights the serious antibiotic resistance in CR pathogens, emphasizing the need for targeted antimicrobial therapy.
    • Recommends performing antimicrobial susceptibility tests before antibiotic treatment for CR.
    • Suggests broad-spectrum antibiotics with beta-lactamase inhibitors (e.g., Cefotaxime, Amoxicillin-clavulanate) when susceptibility testing is not feasible.
