Comparison of two AFLP methods and PFGE using strains of Listeria monocytogenes isolated from environmental and food samples obtained from Piedmont, Italy

► We typed 103 well characterized L. monocytogenes food and environmental strains. ► We compared two AFLP methods and PFGE in characterizing the same set of samples. ► We evaluated discriminatory power, typeability and concordance of the three methods. ► We evidenced a low typeability for one of the AFLP method considered. ► We observed similar discriminatory power and a good agreement between methods.
