This chapter describes the methods to extract and characterize plasmids of Gram-positive bacterial species of interest in public health (biomedicine, veterinary, and food safety) as Staphylococcus, Streptococcus, Enterococcus, Listeria, and Clostridium and lactic acid bacteria. References for detailed plasmid classification are given in order to provide a comprehensive landscape in the interpretation of their plasmidomes.
