How I Found My Superorganism
Scientific Challenge If you could pick ONE sign that best distinguishes a lifetime of health from one filled with disease ……what would that be???? [Challenge was issued for an invited paper for a special issue of the physics journal ENTROPY]
My Answer(upon waking from a dream) Self completion of the human-microbial superorganism

What I Learned From My Superorganism
The Complete Human: Three Domains of Life Eukaryota Archaea Bacteria Majority- Microbial Humans (based on cell and gene numbers) Domains of Life Genomes First ~ 25,000 genes Approximately 90% microbial by cell number Second ~ 10 million genes Superorganism Mammalian Microbial Eukaryotes
Archaea – also in your gut
Earlier Microbial Partners Lynn Marguluis, famed biologist (former spouse of Carl Sagan), published her endosymbiosis theory in 1967concerning the bacterial origins of both mitochondria and chloroplasts. Crisp et al. Genome Biology 2015, 16:50 New examples of horizontally transferred genes were recently identified in humans. Apparently, our second genome can become part of our first genome.
Our Microbiome Produces a “Fingerprint”of Volatile Organic Compounds (VOCs) Arasaradnam et al. PLoS One. 2014 Oct 16;9(10):e107312. Volatile organic compounds (VOCs) in urine can be used to differentiate celiac disease from irritable bowel syndrome based on distinctive microbiome-produced metabolites. Bezerra de Araujo Filho et al. Archaea. 2014 Oct 13;2014:576249. Children living near a sanitary landfill had elevated breath methane correlated with elevated methane producing Archaea in the gut microbiome (unrelated to socio economic status).

Who are you really? and…. How (healthy) are you?
Microbiota are seen as an “Integral Organ”If they are missing, it analogous to a form of birth defect. Ramifications of Self Incompleteness e.g., Clarke et el., Minireview: Gut microbiota: the neglected endocrine organ. Mol Endocrinol. 2014 Aug;28(8):1221-38. Brown JM, Hazen SL. The gut microbial endocrine organ: bacterially derived signals driving cardiometabolic diseases. Annu Rev Med. 2015 Jan 14;66:343-59. Evans et al. The gut microbiome: the role of a virtual organ in the endocrinology of the host. J Endocrinol. 2013 Aug 28;218(3):R37-47.

Is it safe?The New “Organism” for Safety
Environmental chemicals and drugs reported to affect the gut microbiome(Note added: In contrast with antibiotics, Vitamin D is on the list because it affects, but does not necessarily “harm,” the microbiome. Many people are, in fact, deficient in Vitamin D. In the Ooi et al. paper listed below, it shifts the microbiome to increase protection AGAINST colitis) Heavy metals (e.g., cadmium, lead, arsenic) Other metals (iron, selenium, zinc) PCBs (Choi et al., EHP 2013) Particulate matter (PM10) (Kish et al. PloS One 2013) Chlopyrifos (Joly et al, ESPRI, 2013) High fat diet (Myles et al. Plos One 2014) Valproate (de Theije et al. Brain Behav Immun 2013) Antibiotics (Ng et al., Nature 2013) Vitamin D (Ooi et al., J.Nutr 2013)

How I Trained My Superorganism(and you can too)
My Personal Superorganism Later-Life Training Problem: 30 years of multiple rounds of antibiotics. each year. Solution:Adjusted my microbiome, adjusted what I fed it. Best year for my health in at least 30 years. Qualifications: I am not a MD. This is my personal story and it is not intended to be nor is it medical advice.

Three Take-Home Points Failure to self-complete in the newborn may be the single greatest health risk across a lifetime. We need microbiome seeding on every birth plan and active management of our “second genome” (i.e., seed, feed, protect). The immune system and the microbiome need to co-mature in a narrow window of development or persistent immune dysfunction and elevated risk of NCDs are likely. Safety needs to be based on the whole human. It is the superorganism that needs protection.

Thank You! Discussion …….and Yoghurt Thanks to Ithaca Water Buffalo
Ithaca Water Buffalo Ithaca Water Buffalo maintains a herd of 100 female animals. Water Buffalo produce about 2 gallons of milk a day. Milk is heated and pasteurized (170? F for 30 min) Milk is cooled to 100?F Yogurt Culture is added Cultured Milk is placed in the cup Milk is incubated ay 100?F for ~ 12 h “Probiotic” Bacteria ferment the milk sugar (lactose) into acid (lactic acid) Yogurt is blast chilled to 36? F to “set” the solid Yogurt is boxed and shipped to the store
