Genome[edit]
Clostridium perfringens has a stable G+C content around 27–28% and average genome size of 3.5 Mb. Genomes of 56 C. perfringens strains have since been made available on NCBI genomes database for the scientific research community. Genomic research has revealed surprisingly high diversity in C. perfringens pangenome, with only 12.6% core genes, identified as the most divergent Gram-positive bacteria reported. Nevertheless, 16S rRNA regions in between C. perfringens strains are found to be highly conserved (sequence identity >99.1%).

Clostridium Perfringens Enterotoxin (CPE) Gene
The clostridium perfrigens enterotoxin (CPE) producing strain has been identified to be a small portion of the overall population of this particular species (~1-5%) through genomic testing. The CPE gene has been found within chromosomal DNA as well as plasmid DNA. Advances in gentic information surrounding strain A CPE Clostridium perfringens has allowed techniques such as microbial source tracking (MST) to identify food contamination sources.
