“Clostridioides difficile (C. difficile) is a bacterium that can cause a nasty spell of diarrhea and colitis for those unlucky to be infected. Now, researchers analyzing the genomes of various strains in Nature Genetics have discovered it is a millennia-long process of evolution that will see it separate into two different species. One of those species is particularly adept at evading hospital disinfectants and thrives on a sugar-rich Western diet. "This largest ever collection and analysis of C. difficile whole genomes, from 33 countries worldwide, gives us a whole new understanding of bacterial evolution," author Brendan Wren, a professor at the London School of Hygiene and Medicine, said in a statement. "It reveals the importance of genomic surveillance of bacteria. Ultimately, this could help understand how other dangerous pathogens evolve by adapting to changes in human lifestyles and healthcare regimes which could then inform healthcare policies." C. difficile is the leading cause of antibiotic-associated diarrhea – "good" gut bacteria will fend off the bug in a healthy person but antibiotics extinguish "good" gut bacteria, leaving the patient vulnerable to infection. Because of this, the bug is frequently found in hospital settings. For the study, the team sequenced the genome of 906 strains, collected from humans and other animals as well as the environment. The researchers then compared the genomes from each strain to find that it is evolving into two different species. The emerging species (called C. difficile clade A) accounts for roughly 70 percent of the samples collected from hospital patients.
