Description
Jaehyun Choi and co-authors sequence in 2026 four Clostridium perfringens isolates from separate South Korean food poisoning outbreaks to learn where their enterotoxin gene lives. That gene, cpe, can sit on the chromosome or ride on a plasmid, and its address shapes how outbreaks spread. All four isolates carried the gene: three on the chromosome, one on a plasmid, and public genome collections supplied a wider comparison set.
Across genomes, plasmid carriage proved the common pattern, with chromosomal strains the exception. Chromosomal copies sat in one conserved spot, flanked by jumping-gene machinery that hints at inheritance down generations. Plasmid copies travelled on a shared plasmid family instead, spreading the toxin gene sideways into new backgrounds. The two lifestyles matched distinct core-genome and virulence profiles.
