Yersinia Pestis

Yersiniazia pestiz is a pathogenic bacterium that causes plague. Plague is one of the most devastating diseases in human history and can be fatal to humans if not treated quickly. However, thanks to our efforts and scientific advances, we have been able to develop methods for treating and preventing this disease.

The bacterium yersiniapestida was discovered in 1894 by the Russian doctor F.F. Haase. He was the first to use the term “plague” to describe the disease caused by this bacterium. Since then, the plague has become one of the main threats to public health and has reached enormous proportions during epidemics.

Plague is caused by the bacterium Yersiniapestiz. This is a rod-shaped bacterium that is not stained with aniline dyes, but contains a capsule or cortex, which makes it difficult to detect in tissues and body fluids. The bacterium secretes a protein called endotoxin, which acts on body tissue, causing symptoms of the disease. However, it is important to understand that until the disease has reached a critical point, it is asymptomatic for humans, so at the initial stage the infection can easily be undetected.

The main route of transmission of infection is through airborne droplets: through sneezing, coughing, or through prolonged close contact with a sick person. Today there is a vaccine against this disease. If a person has been vaccinated, he is not afraid of various diseases that lead to increased work of the respiratory system and lungs. The vaccine is given exclusively during the incubation period. To create it, fragments of proteins from plague bacteria were used. There is both a Soviet and an American vaccine. The second version of the drug is recommended against outbreaks of epidemics, the first - in case it is necessary to administer a larger amount of vaccine at a time to several people. In both cases, vaccination tests must be carried out before administering the drug.
