Genetic Profiling of MRSA and MSSA from Food Contact Surfaces: Antibiotic, Heavy Metal and Benzalkonium Chloride Resistance.

ABSTRACT: Staphylococcus aureus is a foodborne pathogen that affects animals and humans. The persistence of this pathogen in the environment is associated with its ability to form biofilms and/or develop resistance mechanisms to antibiotics and sanitizers. A total of 67 S. aureus strains collected from food contact surfaces (FCSs) made of stainless steel and FCS-polypropylene used in dairy industries in Jalisco, México, were selected for this study. The genetic diversity and genes indicating antibiotic resistance were determined using PCR; antimicrobial susceptibility, resistance to cadmium chloride (CdCl₂), and the minimum inhibitory concentration (MIC) of benzalkonium chloride (BC) were determined using the agar diffusion method and broth microdilution. Additionally, the e
