Detection of enterotoxin gene (sea) and biofilm formation ability among multidrug resistant Staphylococcus aureus isolated from shawarma sandwich sold at selected kiosks in Klang Valley, Malaysia
The occurrence of multi-drug resistant Staphylococcus aureus in food product of animal origin has increased the concern about their spread into the food supply chain. Presence of multidrug-resistant S. aureus in food products, including ready-to-eat foods imposes potential hazard for consumers. The...

The occurrence of multi-drug resistant Staphylococcus aureus in food product of animal origin has increased the concern about their spread into the food supply chain. Presence of multidrug-resistant S. aureus in food products, including ready-to-eat foods imposes potential hazard for consumers. The objective of this research was to investigate the presence of multi-drug resistance of S. aureus in sixty ready-to-eat shawarma sandwiches. Agar-disc diffusion assay determined their resistance to 11 antibiotics. The sea and sed enterotoxin genes were detected by polymerase chain reaction method. Biofilm formation potential (BFP) was quantified by microtitre plate assay. The result revealed that thirty-six samples (60%) were positive for S. aureus.
