Abstract In the present study, a loop-mediated isothermal amplification (LAMP) method was applied to rapidly detect
Staphylococcus aureus in porcine blood samples. The femA sequences of Staphylococcus aureus CMCC10201 were used
as target sequences to design outer primers and inner primers. Amplification products were analyzed by gel electrophoresis.
Eight common pathogenic bacteria were used to test the specificity of the LAMP method, and high specificity to
Staphylococcusaureus was observed, reaching 8.7 CFU/mL. The limit of detection for Staphylococcus aureus in poricine
blood was 8.7 × 102 CFU/mL compared with 8.7 × 103 CFU/mL with PCR. The LAMP method was rapid and highly
specific and sensitive
