Sure, I could have said ‘faecal matter’ but why would I when this episode is probably the only chance I’ll ever have to legitimately use ‘poo’ in a title; especially when I’m chatting with one of the world’s foremost authorities in the area of all-things gut health. Dr. Mahmoud Ghannoum is a tenured Professor and Director of the Centre for Medical Mycology at Case Western Reserve University and University Hospitals Medical Centre. He has published over 400 peer-reviewed articles in the field of biofilms, the microbiome, microbial pathogenesis and preclinical in vitro and in vivo evaluations of antimicrobials. He also published the first study describing the oral mycobiome of healthy individuals, and the interaction between bacteria and fungi in the microbiomes of Crohn’s patients. His work has been cited over 26,000 times in the medical literature. Enjoy.
