hello, I am studying gut flora and had a few questions.

1.) how do microbiologist test the abundance of certain types of bacteria in the gut.

2.) what does increasing the amount of certain bacteria such as E.coli and lactobacillus do to someone\'s body or health.

3.) how does changing the metabolism. pathways or amount of their activity in gut flora impact a person\'s health?

Solution

Gut flora in human beings contains largest number of bacteria which play an important role by leading mutualistic relationship with the host by fermenting dietary fibres and play important role in synthesizing Vitamin B and its weight when the diet changes the composition of that the flora changes.

The reason relation between concentration of microbial community and intake of diet for example Sree Hotel Le is related to Carbohydrate, bacteroidetes is related with protein and saturated fats. Malnourishment results in the decrease of microflora and increased pathogenic floram leading to alterations in gut microflora composition and diversity. There is also some source of evidence that microflora influence eating behaviours leading to consumption more food resulting in obesity.

It is not possible to isolate majority of human microbiome isolate and the grow in the laboratory condition but recent technological advances like metagenomics help us to analyse without calculating the microorganisms they can be from where natural environment and there determinants of different species can be determined.

the lifestyle factor likr t strss will have impact on the important microbiota like lactobacillus and decrease the number poor health outcomes result in increased number of e coli. High fat diet result in increased circulating levels of bacteria due to increased intestinal permeability .dietary polyphenols found in grapes varieties promote health And r linked to prevent diseases like cardiovascular and cancer.

The number of e coli increase in colitis and by the pathogenicity cause r various diseases. Yusuf alaihis kar Asia and the lactobacillus are present in lesst the number. laptop bacillus use beneficial bacteria living in small intestine which prevent bad hair and soft pathogenic organisms and compete against pathogens including e.coli. help in digestion and produce vitamind. E.coli- They are associated with imbalance of microbiota of lower reproductive tract of women there are more pathogenic species commonly causing urinary tract infections like diarrhoea dysentery.
