Beneficial bacteria and dangerous bacteria

Anatori Sealife Comments 0 1st November 2018

Bacterial infections are considered among the most dangerous. Humanity has been struggling with pathogenic microorganisms for more than one century. However, not all bacteria are unequivocal enemies for humans, and there are beneficial bacteria. Many of their species are vital, as they provide proper digestion and even help the immune system to defend against other microorganisms.
It is believed that harmful and beneficial bacteria appeared on Earth more than 3.5 billion years ago. They became active participants in the creation of suitable conditions for life on the planet, and throughout their existence, they take an active part in essential processes. For example, it is thanks to bacteria that the organic remains of animals and plants disintegrate. They also created fertile soil on the Earth.
The human body is no exception because bacteria live literally everywhere. Many microorganisms that interact in different ways with humans live on the skin, mucous membranes, in the gastrointestinal tract, nasopharynx, and urogenital tract.

Beneficial bacteria in the human body

The placenta protects the fetus in the womb from the penetration of bacteria, and the colonisation of the infant’s body occurs in the first days of life:

  • The baby receives the first bacteria passing through the birth canal of the mother.
  • Microorganisms enter the gastrointestinal tract when feeding a baby with breast milk. Lacto-and bifidobacteria (the beneficial effect of which is described in the table of bacteria at the end of the article) prevail here, among more than 700 species.
  • Staphylococci, streptococci, and other microbes also colonise the baby’s mouth during meals and on contact with objects.
  • The microflora on the skin is formed from bacteria that predominate in the people around the child.

The role of bacteria for man is invaluable. If the microflora is not formed effectively in the first months, then the child will lag behind and often get sick. After all, the body can not function without symbiosis with bacteria.
Everyone knows the concept of dysbacteriosis – a condition in which the natural microflora in the human body is disturbed. Dysbacteriosis is a severe factor in reducing the immune defence, the development of various inflammations, disorders of the gastrointestinal tract and other things. The absence of beneficial bacteria contributes to the reproduction of pathogenic organisms, and often fungal infections develop due to dysbiosis.
At the same time, many pathogenic microbes in the environment can cause serious illnesses. The most dangerous are the types of bacteria that are capable of producing toxins (exotoxins) in the course of their vital activity. These substances are considered today one of the most potent poisons. Beneficial bacteria, on the contrary, support the health of the body. Colonic irrigation will help cope with violations of the microflora of the body.
