Overview

Retrospective analysis shows significant shifts in non-typhoidal salmonella serotypes and rising antimicrobial resistance, emphasizing the need for improved surveillance.

Key Points

  • A significant rise in antimicrobial resistance in non-typhoidal salmonella was observed, particularly for cefoxitin and tetracycline.
  • The study analyzed 1,028 salmonella isolates over 63 years, revealing notable shifts in serotype dynamics.
  • Genetic analysis identified S. Gallinarium with over 70% prevalence of antibiotic resistance genes, indicating a concerning trend.
  • These findings underscore the urgency of implementing effective antimicrobial stewardship and surveillance strategies.
