RESUMEN
Food samples (nâ¯=â¯216) from New York city were tested for the presence of C. perfringens via PCR for specific toxin genes. Thirty-four (16%) samples were positive for C. perfringens. Of these 34, 31 (91.2%) were type A or E, one (2.9%) was type B, and two (5.9%) were type D.

IMPORTANCE: Clostridioides difficile and Enterococcus faecalis are two pathogens of great public health importance. Both bacteria colonize the human gastrointestinal tract where they are known to interact in ways that worsen disease outcomes. We show that the damage associated with C. difficile infection (CDI) releases nutrients that benefit E. faecalis. One particular nutrient, heme, allows E. faecalis to use oxygen to generate energy and grow better in the gut. Understanding the mechanisms of these interspecies interactions could inform therapeutic strategies for CDI.
