Profiling of Antimicrobial Resistance Genes and Genotype-Phenotype Associations in Salmonella spp. Isolated Along the Broiler Production Chain in Karnataka, India.

Key Points

• The aim is to profile antimicrobial resistance genes and understand their associations with phenotypic traits in Salmonella spp. isolated from the broiler production chain.
• Isolates of Salmonella were collected along the broiler production chain in Karnataka, India.
• Genetic analysis was conducted to identify antimicrobial resistance genes present within the isolates.
• Phenotyping of antimicrobial resistance was performed to assess resistance patterns.
• Diverse antimicrobial resistance genes were identified across the isolates, indicating high levels of resistance.
• Clustering of resistance phenotypes did not show clear separation by source, suggesting widespread dissemination of resistance.
• Call for enhanced biosecurity and surveillance measures was emphasized to mitigate antimicrobial resistance.
