CRISPR Typing of Salmonella Isolates from Different Resources

CRISPR typing is a newly developed method used to reveal the genetic relationship of bacterial isolates from different resources. For Salmonella, CRISPR typing can not only reveal the phylogenic difference among isolates belonging to the identical serotype, but also show good correspondence with Salmonella serotypes. Here we describe the protocol of CRISPR typing method used in Salmonella, and the approaches to analyze the genetic relationship among different strains.
