The integration of next-generation sequencing into the identification and characterization resistant virulent strains as well routine surveillance foodborne pathogens such Salmonella enterica have not yet been accomplished in Philippines. This study investigated antimicrobial profiles, virulence, susceptibility 105 S. isolates from swine chicken samples obtained slaughterhouses public wet markets Metropolitan Manila using whole-genome sequence analysis. Four predominant serovars were...

Abstract Background Salmonella are pathogenic foodborne bacteria with complex pathogenicity from numerous virulence genes housed in islands (SPIs), plasmids, and other gene cassettes. However, distributions mechanisms remain unestablished. In the Philippines, studies mainly report incidences antimicrobial resistance, but little to none on profiles, their associations animal sources, collection sites serogroups. Hence, a total of 799 isolates, previously obtained pig, cow, chicken meat...

Salmonella enterica is known as one of the most common foodborne pathogens worldwide. While salmonellosis usually self-limiting, severe infections may require antimicrobial therapy. However, increasing resistance to antimicrobials, particularly fluoroquinolones and cephalosporins, utmost concern. The present study aimed investigate susceptibility S. isolated from pork, major product in Philippine livestock production. Our results show that both qnrS blaTEM genes were 61.2% isolates. qnrA...

Abstract Background: Salmonella enterica is known as one of the most common foodborne pathogens worldwide. While salmonellosis usually self-limiting, severe infections may require antimicrobial therapy. However, increasing resistance to antimicrobials, particularly fluoroquinolones and cephalosporins, utmost concern. The present study aimed investigate susceptibility S. isolated from pork, major contributor in Philippine livestock production. Results: Our results show that 61.2% isolates...
