Determination of the cases of S. aureus infection in 160 clinical samples from patients with diabetes foot. A Comparing three methods for identifying the number of patients with S. aureus infection. Of the 160 clinical samples collected, S. aureus was detected in 47 samples using the enrichment culture method, in 54 samples using the LAMP assay technique, and in 29 samples using the clinical hospital laboratory culture method. B S. aureus strains in four clinical samples were analyzed using the LAMP assay targeting the femA gene. These four clinical samples could only be identified S. aureus in enrichment culture, while the results were negative in the LAMP test and clinical laboratory culture
