Exploration of the Diversity of Clustered Regularly Interspaced Short Palindromic Repeats-Cas Systems in Clostridium novyi sensu lato.

ABSTRACT: Classified as the genospecies Clostridium novyi sensu lato and distributed into four lineages (I-IV), Clostridium botulinum (group III), Clostridium novyi, and Clostridium haemolyticum are clostridial pathogens that cause animal diseases. Clostridium novyi sensu lato contains a large mobilome consisting of plasmids and circular bacteriophages. Here, we explored clustered regularly interspaced short palindromic repeats (CRISPR) arrays and their associated proteins (Cas) to shed light on the link between evolution of CRISPR-Cas systems and the plasmid and phage composition in a study of 58 Clostridium novyi sensu lato genomes. In 55 of these genomes, types I-B (complete or partial), I-D, II-C, III-B, III-D, or V-U CRISPR-Cas systems were detected in
