Diversity of CRISPR-Cas Systems Identified in Urological <em>Escherichia coli</em> Strains

2025-11-03

Abstract excerpt

The type I-E and I-F CRISPR-Cas systems were identified in 237 E. coli strains isolated from patients with urinary tract infections (UTIs) between 2004 and 2019. The strains were classified into nine distinct groups (I-IX) based on the presence or absence of cas genes and repeat regions (RRs). Within the type I-E systems, two sequence variants were identified, distinguished by polymorphisms in the casB, cas3, cas7...
