The journal Clinical Infectious Disease recently published findings showing that a cluster of antibiotic-resistant bacteria called Campylobacter coli has been found in a number of men who have sex with men (MSM) in Seattle, Wa., and Montreal, Canada. According to researchers, one of the bacterial strains has acquired a new gene that makes it able to resist antibiotics via the DNA sequences known as CRISPR, Clustered Regularly Interspaced Shortchanged Palindromic Repeats. (Not to be confused with the gene-editing technology also known as CRISPR.)
