A Global Comprehensive Study of the Distribution of Type I-E and Type I-E* CRISPR-Cas Systems in .

Background: The CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR-associated proteins) systems are the short DNA sequences and RNA-dependent nuclease involved in the adaptive immunity in bacteria and archaea. The type of CRISPR-Cas system influences antibiotic susceptibility in . Here, our objective was to study the diversity of CRISPR-Cas system in the genome of from the available whole genome sequencing (WGS) data.
