Antibiotics and the Human Microbiome

Antibiotics and Microbiome

Quite often, patients who have completed a course of antibiotics develop diseases such as dysbiosis, diarrhea, thrush, and sometimes pain in the liver or kidneys.

How do antibiotics work?

Antibiotics can affect bacteria, fungi and tumors. But they are useless to use against viruses.

The name “antibiotic” comes from the Greek words “anti” and “bios”. That is, in the literal sense, “antibiotic” means “against life.” In fact, antibiotics have saved and continue to save the lives of many people. How do they do it?

All antibiotics are divided into bactericidal and bacteriostatic. As a result of bactericidal antibiotics, bacteria die, and when used bacteriostatic they lose the ability to multiply, and the immune system helps the body to cope with the disease. Therefore, if a person’s immune system is weakened, bactericidal antibiotics are used.

There are also broad-spectrum antibiotics and narrow-spectrum ones. The wider the spectrum of action of the antibiotic, the greater the number of different bacteria it is able to destroy.

The human body has its own microflora, which ensures the normal course of all life processes and inhibits the reproduction of various pathogenic bacteria and fungi. So, broad-spectrum antibiotics can inhibit the growth and development of the beneficial bacteria that make up this microflora. This lead to a reduction of bacteria that help the body produce vitamins, absorb nutrients, regulate the bowel. Digestion is disturbed, and a person experiences diarrhea, colitis, inflammation of the gastrointestinal tract and the urinary system.

How to restore the microflora after taking antibiotics?

The microflora is restored with the help of probiotics and prebiotics.

  • Probiotics are living organisms that are present in the human body and neutralize intestinal toxins. These are bifidobacteria and lactobacilli. They are found in kefir and natural yogurt. Probiotics are easy to get at home by preparing yogurt or kefir from milk and sourdough.;
  • Prebiotics are foods that improve intestinal function. These are pectins, gums and mucus. They are found in foods such as rice, beans, fruits, berries.

During the treatment of dysbiosis, a patient should not eat sweet foods, as it contributes to the development of pathogenic microorganisms. And you’d better replace wheat bread with the bran or bread from coarse flour.

Canadian Pharmacy also recommends that you increase the consumption of cottage cheese. Green tea will also help restore the microflora – it’s an active natural antioxidant. Dried strawberries, raspberries, black currants, dried St. John’s wort or chamomile, added to tea, will also benefit the body.

We should not forget about the daily walks in the air, hardening and sports.

All these measures will help the body to recover very quickly after taking antibiotics.

“Smart” antibiotics will destroy pathogenic bacteria, without affecting beneficial ones

In order to cope with bacterial infections, you can use a variety of antibiotics. However, by killing harmful bacteria, they also act on beneficial ones, and these beneficial bacteria often inhibit the development of an infection caused by the bacterium Clostridium difficile. This microorganism can cause diseases of the gastrointestinal tract, such as pseudomembranous colitis and others. If a person does not take antibiotics, the beneficial bacteria of his microbiome control the action of harmful, including Clostridium difficile. However, the introduction of an antibiotic into a balanced system disrupts the balance, leading to the emergence of extremely unpleasant symptoms. Scientists from Penn State College of Medicine have developed a new approach to the treatment of Clostridium difficile infection. They proposed “smart” point-directed antibiotics that only affect “bad” bacteria and not any others. Such antibiotics are already presented in the catalog of My Canadian Pharmacy. For simple ordering, you should only visit and place an order online.

Specialists have created three new drugs that kill only Clostridium difficile, preventing the expression of genes necessary for the survival of these microorganisms. Such therapy does not affect other bacteria. Scientists explained that their method refers to the methods of antisense therapy. Drugs consist of two components – one of them acts as a “gunner” on the genetic material of the bacterium, and the second kills what it is “aimed” at. Having tested all three products, the authors of the scientific work determined which of them is the most effective and least toxic for the organism and other bacteria and will now work on further improvement of its properties.
