Antibiotics increase susceptibility to diseases

12 July 2016, 16:00

In the human body, millions of microorganisms live, both useful and not very much.

Most of the bacteria is in the intestines, and is responsible for the functioning of the immune system.

Human heredity includes not only the DNA of the cell, but also microorganisms, and, according to scientists, it is the DNA of microbes that is most influenced - it can be destroyed, depleted, supported, strengthened. Scientists have already been shown that intestinal bacteria can control certain body functions, including preventing the penetration of toxins into the blood, thereby protecting the brain from dangerous chemical changes and mental disorders.

Scientists have long established that human health depends on the state of the intestine, but modern methods of treatment can significantly disrupt the balance of microflora and trigger the growth of pathogenic flora, in particular, in recent years, doctors prescribe antibiotics for any diseases, especially in childhood, often such drugs are prescribed it is inappropriate.  

In childhood, when immunity is only being formed, taking antibiotics can cause destruction not only of pathogenic microorganisms, but also of beneficial bacteria. Such treatment, if necessary, will ultimately kill microbes, but beneficial bacteria will also suffer, eventually the immune system will not be able to withstand new viruses and infections.

According to scientists, not only antibiotics can destroy pathogenic microbes, active participation in this takes directly the body of the patient, or rather its immune system, which not only fights pathogens, but also does not destroy useful microflora. Antibiotics should be taken only in extreme cases, when the disease is started, the body is exhausted and unable to fight the disease on its own.

In one of the Canadian universities (Vancouver), a team of specialists once again confirmed the fact that taking antibiotics at an early age contributes to the emergence of specific diseases in a more adult age. Also, scientists noted that antibacterial drugs destroy all microflora in the intestines, both pathogenic and useful.

Kelly McNeny, the chief specialist in the Department of Medical Genetics of the University, noted that the new study will help determine the bacteria vital for normal immunity work. In the course of the work, 2 antibacterial drugs were tested.

Scientists studied streptomycin and vancomycin, and in both cases, antibiotics showed a different effect, as the microflora in the intestine was changed in different ways.

In the treatment of streptomycin-grown mice, adult rodents were more susceptible to allergic alveolitis, while there were no such phenomena in the vancomycin group. 

According to scientists, this difference is primarily due to the different effects of antibiotics on the intestinal microflora, most likely, streptomycin destroys along with pathogens most of the beneficial bacteria responsible for protecting the body from allergic alveolitis.

The latest research relating Antibiotics increase susceptibility to diseases

American experts are sure that in the near future antibiotics will be completely replaced by bacteriophages - special viruses that affect pathogenic bacteria.

Scientists managed to prove experimentally that taking certain antibiotics can cause the development of kidney stone disease.
The patients of children and adolescents are more prone to this complication.
