Microbiota indigenous flora includes various bacteria, arches, fungi, protozoa, viruses, and arthropods(mites)
Sterile environments of the human body Lung, sinus, kidneys, blood, fetus
How does the microbiota benefit the host prevent the overgrowth of harmful microbes and modulate an immune response
Type of helpful bacteria found in the vagina Lactobacillus which is inhibitory to pathogenic yeast
Beneficial probiotic bacteria found in breastmilk Bifidobacterium
Current research has found some evidence that the gut microbiota has influences on obesity inflammatory bowel and chron's disease autism brain function alzheimers
How does antibiotic treatment change the microbiota disrupts the normal flora and causes the overgrowth of harmful species
What bacteria causes antibiotic associated colitis Clostridium difficile
What causes bacteria causes antibiotic associated yeast infections such as oral thrush, vaginal candidasis Candida albicans
What is linked to use of antibiotics in early childhood later onset asthma
Why are normal flora important immunnomodulation and host response to environmental substances
What type of influence does the microbiota have on the human host produce compounds to change the gene expression of intestinal epithelial cells influence what the body does with genes
How do microorganisms work with the human gut They can cause the gut to become leaky and allow LPS from the G- bacteria to get into the body and the brain is particularly sensitive
How can microorganisms help the gut by maintain the borders of the gut and preventing the leakage of toxins into the body
Usage of antibiotics and intake of simple sugars encourages Bad bacteria
Intake of fiber and fermented foods encourages Good bacteria
What amino acid comes from good gut bacteria Tryptophan
What is the purpose of tryptophan is it used by the body and turned into the calming neurotransmitter serotonin
Probiotics good bacteria ingested in order to attempt to positively influence gut bacteria
What are the important factors when choosing a probiotic variety and species are important need to be fresh and living numbers are important delivery system
Why are numbers of probiotic ingested important because most die in the journey of through the gi tract
What are probiotics foods that cannot be digested by humans but make it through the gi tract and are food for good bacteria
