Microbial imbalance of the intestinal biome is a key associated factor in many chronic conditions including Myalgic Encephalomyelitis (ME/CFS). Our major research goals are too increase our understanding of ME/CFS and open up new treatment options. If a leaky gut is a key component of ME/CFS, restoring a normal gut microbiome balance could be a life changing treatment options. Our collaborator SoftCell Biologicals Research (SBR) have developed approaches examining the host tissue biome. This is an un-tapped area of medicine with the presence of significant levels of wall-less (L-Form) opportunistic pathogens present in many chronic disease states. Using novel L-Form culturing methods SBR have treated L-form cultures from patients with chronic urinary tract infections (CURTIs) using a standard antibiotic panel. Clinicians acting on this information have noticed improvements in a number of patients. Clinical studies, using this approach will allow antibiotics tested in the laboratory to be used to treat patients in a blinded trial setting. In this presentation, I will highlight our research with the Doveclinic exploring levels of gut dysbiosis in a broad range of conditions many of whom suffer with fatigue. The impact of age and sex on the gut microbiome will be explored with a focus on ME/CFS and cancer. Exciting data from a comparison of recent trials of Gut Floral Replacement Therapy (GFTR) to the more conventional Faecal Microbiota transplantation (FMT) will be presented.
