Trying to do a crash course in understanding the faecal anaerobes & aerobes results I have. Gosh, Sarah Myhill has an enlightening website on the human bowel and its amazing structure and function. I never really knew its intricacies! OK. My results which are aberrant are: Anaerobes Bacteroides spp. - relative absence 1.72% (normal 90-95%) Prevotella sp. - overgrowth 11.48% (normal <10%) Porphyromonas sp. - overgrowth 51.65% (normal <10%) Eubacterium spp. - overgrowth 35.1% (normal <15%) Lactobacillus - undergrowth 0.00% (normal 0.5-1.5%) Bifidobacterium spp. 0.14% (normal 5-11%) Clostridium spp. 0.00% (normal 1-10%) Peptostreptococcus spp. 0.00% (normal 1-10%) Aerobes Coliforms E-coli 99.96% (normal 70-90%) Other Aerobes - Enterococcus, Streptococcus, Staphylococcus all normal Yeast - also normal. Wondering if anyone can shed some light on the implications of these? My main concern is the very low level of Bacteroides Fragilis which I gather may have the most health implications!
