In a nutshell our bodies contain trillions of symbiotic bacteria that make up our normal intestinal flora
. Many assist in digestion including the synthesis of vitamins and the fermentation (breakdown) of carbohydrates.
It is somewhat of interest to discuss the damaging effect on the intestinal flora
balance of chlorine and sodium fluoride, which are substances that are present in most treated city water systems, and by extension found in most consumed beverages.
Therefore, it seems that changes in the composition of intestinal flora
(dysbacteriosis) may be reflected by elevated serum levels of D-lactate in CF patients, especially those with exocrine pancreatic insufficiency.
Most chronic HBV infections occur in infants and young children due to their immature immune systems and unstable intestinal flora
Insufficient acid secretion, together with stress, such as the need to rapidly adapt to dramatic changes in the social and physical environments and weaning, may disturb the balance of intestinal flora
and allow the proliferation of coliforms, resulting in scours and poor performance .
The inclusion criteria were as follows: (i) the subjects had not received antacids, probiotics, antibiotics, or antimicrobial agents within 30 days before sample collection; (ii) there was no organic disease of the digestive system; (iii) they had no gastrointestinal surgery; (iv) there was no history of alcohol abuse, diabetes, or other disease which may affect the intestinal flora
; (v) subjects were residents of southern China at the age of 50-85 years.
Comparing the intestinal flora
of vaginally delivered infants and those born by Caesarean section, we noticed that there is a homogeneous distribution of the genera Enterococcus, Streptococcus and Lactobacillus (P-value> 0.05).
Bifidobacteria colonizes the intestinal surface during the first days after birth, and continues to be a member of intestinal flora
in humans and animals throughout life (17).
By eating probiotic-rich foods and maintaining good intestinal flora
, a person can also help to maintain a healthy immune system.
Animal studies show that the makeup of organisms in the gastrointestinal tract (intestinal flora
) can affect brain development in young animals, influencing specific behaviors such as anxiety.
Therefore, the study of the silkworm intestinal flora
, enzyme production and biological function will play important roles in the improvement of the intestinal micro-ecological environment of the silkworm and in the development of an artificial diet.
But ubiquitous and powerful antibiotics can overwhelm our own intestinal flora
, which may lead to widespread autoimmune diseases.
