Overview

Combined phenotypic and molecular study reveals high multidrug-resistant strains in poultry flocks, indicating significant public health risks.

Key Points

  • The study aims to investigate antimicrobial resistance patterns and resistance genes in Salmonella enterica serovar Gallinarum–Pullorum from poultry in Bangladesh.
  • Collected 200 samples from chickens suspected of salmonellosis based on clinical diagnosis
  • Performed polymerase chain reaction (PCR) for serovar identification and antimicrobial susceptibility testing on PCR-positive isolates
  • Analyzed resistance genes using PCR-based detection methods
  • 138 samples tested positive for serovar Gallinarum–Pullorum by PCR
  • 89.13% of isolates were multidrug-resistant with the highest resistance seen for amoxicillin (71.01%) and tetracycline (73.91%)
  • The most prevalent resistance genes identified were tetA (74.64%) and sul1 (73.19%)
