Objective:

To investigate alterations in the microbiological characteristics of bloodstream infections (BSIs) before and after the COVID-19 pandemic.

Approach:
  • Study Design: Retrospective analysis of BSIs over six years, comparing pre-pandemic and pandemic periods.
  • Microbial Analysis: Assessment of pathogen distributions and resistance patterns in BSIs.
Key Findings:
  • Gram-negative organisms predominated in the etiological profile of BSIs.
  • Increased prevalence of Enterobacterales (E. coli, Klebsiella spp., Enterobacter spp.) post-pandemic.
  • Significant rise in antimicrobial resistance, particularly among Gram-negative pathogens.
  • MRSA prevalence increased, while vancomycin-resistant enterococci remained high.
  • Decreased prevalence of Stenotrophomonas maltophilia.
Limitations:
  • Methodological differences among studies may affect interpretation of results.
Conclusion:

Ongoing surveillance is critical for informing empirical antibiotic therapy and reinforcing infection control strategies.
