In this article, we'll look at bacteria.

Consider all bacteria living in the body. And we'll tell you all about bacteria.


  • 1 Bacteria
  • 2 Lactobacillus (Lactobacillus plantarum)
  • 3 Bifidobacteria (Latin Bifidobacterium)
  • 4 Unfavorable microbe Corynebacterium minutissimum
  • 5 Streptomycetes
  • 6 Helicobacter pylori belly protector
  • 7 Good bad bacteria Escherichia coli
  • 8 Harmful bacteria. Staphylococcus aureus (Staphylococcus aureus)
  • 9 Pseudomonas aeruginosa (Pseudomonas aeruginosa)

Lactobacilli are your body's defenders against viruses. They live in the stomach since ancient times, performing very important and useful functions. Lactobacillus plantarum protect the digestive tract from useless microorganisms that can lodge in the stomach and worsen the condition.

Lactobacillus helps to get rid of heaviness and bloating in the abdomen, fight allergies caused by various foods. Lactobacilli also help to remove harmful substances from the intestines. Cleans the entire body of toxins.

Bifidobacteria (Latin Bifidobacterium)


It is a microorganism that also lives in the abdomen. These are beneficial bacteria. Under unfavorable conditions for the existence of Bifidobacterium die. Bifidobacterium produce acids such as lactic, acetic, succinic and formic.

Bifidobacterium plays a leading role in the normalization of bowel function. Also, with a sufficient amount of their content, they strengthen the immune system and contribute to the better absorption of nutrients.

They are very useful, as they perform a number of important functions, consider the list:

  1. Replenish the body with vitamins K, B1, B2, B3, B6, B9, proteins and amino acids.
  2. Protect against the appearance of harmful microorganisms.
  3. Prevents harmful toxins from entering the intestinal wall.
  4. Accelerate the digestion process. - Helps the absorption of Ca, Fe and vitamin D.

To date, there are many drugs containing bifidobacteria. But this does not mean that when they are used for medicinal purposes, there will be a beneficial effect on the body, since the usefulness of the drugs has not been proven.

Unfavorable microbe Corynebacterium minutissimum


A genus of bacteria that includes more than 550 species. Under favorable conditions, streptomycetes create filaments similar to mushroom mycelium. They live mainly in the soil.

They are found in drugs such as erythromycin, tetracycline, and so on. They are derivatives of medicines that fight: fungus, microbes (antibacterial agents), tumors.

In 1940, streptomycins were used in the production of drugs:

  • Physostigmine. Pain reliever is used in small doses to reduce eye pressure in glaucoma. May become poisonous in large quantities.
  • Tacrolimus. Medicinal product of natural origin. It is used for the treatment and prevention of kidney, bone marrow, heart and liver transplants.
  • Allosamidine. A drug to prevent the formation of degradation of chitin. It is successfully used for killing mosquitoes, flies and so on.

But it should be noted that not all bacteria of this kind have a beneficial effect on the human body.

Helicobacter pylori belly protector


Microbes that exist in the abdomen. It exists and multiplies in the stomach lining. Helicobacter pylori appear in the human body from an early age and live throughout life. Helps maintain a stable weight, controls hormones and is responsible for hunger.

Also, this insidious microbe can contribute to the development of ulcers and gastritis. Some scientists believe that Helicobacter pylori is beneficial, but despite a number of existing theories, it has not yet been proven how it is useful. No wonder he can be called a belly protector.

Good bad bacteria Escherichia coli


Escherichia coli bacteria are also called E. coli. Escherichia coli, which lives in the lower abdomen. They are settled in the human body at birth and live with him throughout his life. A large number of microbes of this type are harmless, but some of them can cause serious poisoning of the body.

Escherichia coli is a common factor in many infectious diseases associated with the abdomen. But she reminds of herself and gives discomfort when she is going to leave our body, in a more favorable environment for her. And so it is even useful for humans.

Escherichia coli saturates the body with vitamin K, which in turn monitors the health of the arteries. Also Escherichia coli can live for a very long time in water, soil, and even in food, for example, in milk.

Harmful bacteria. Staphylococcus aureus (Staphylococcus aureus)


Staphylococcus aureus is the causative agent of purulent formations on the skin. Boils and pimples are often caused by Staphylococcus aureus, which lives on the skin of a large number of people. Staphylococcus aureus is the causative agent of many infectious diseases.

Pimples are very unpleasant, but just imagine that getting through the skin inside the body of Staphylococcus aureus can get serious consequences, pneumonia or meningitis.

It is present on almost the entire body, but mainly Staphylococcus aureus, exists in the nasal passages and axillary folds, but it can also appear in the larynx, perineum and abdomen.

Staphylococcus aureus has a golden hue, which is why Staphylococcus aureus got its name. It is one of the four most common causes of hospital-acquired infections after surgery.

Pseudomonas aeruginosa (Pseudomonas aeruginosa)

This microbe can exist and multiply in water and soil. Loves warm water and swimming pool. It is one of the causative agents of purulent diseases. They got their name from the blue-green tint. Living in warm water, Pseudomonas aeruginosa gets under the skin and develops an infection that causes itching, pain and redness in the affected area.

This microbe can infect various types of organs and causes a host of infectious diseases. Pseudomonas aeruginosa infection affects the intestines, heart, urogenital organs. The microorganism is often a factor in the appearance of abscesses and phlegmon. Pseudomonas aeruginosa is very difficult to get rid of as it is resistant to antibiotics.

Microbes are the simplest living microorganisms that exist on Earth, which appeared many billions of years ago, are adapted to any environmental conditions. But you need to remember that bacteria are useful and harmful.

So, we have dealt with the types of microorganisms, using an example, we examined which beneficial bacteria help the body and which harmful ones that cause infectious diseases.

Remember that following the rules of personal hygiene will be the best prevention against infection with harmful microorganisms.
