 This study examined three strains of Glostridioids difficile, which are known to cause both mild and severe forms of infection. It found that these strains had evolved through horizontal gene transfer, resulting in a mix of genetic material from different sources. This process allowed them to adapt to their environment and become more resistant to antibiotics. Additionally, it was discovered that the strains shared some similarities in terms of virulent traits, such as antibiotic resistance.
