Evolution of Yersinia Pestis, the Bacteria that Causes the Bubonic Plague

Introduction Although the plague Yerinia pestis is a bacterium that causes glandular plague, one of the well-known symptoms is lymphadenopathy, which is called the emergence of alveolar cells in the body (Perry and Fetherson 1999). Yersinia pestis has evolved from the cloning of pseudotuberculosis during the past 1500 to 20 000 and evolved separately in China (Achtman et al., 1999). Yersinia pestis spreads through fleas, eats infected blood and uninfected blood and contacts the infected blood and opens the wound (Titball et al.

Pestopest is a potentially lethal infection caused by Yersinia pestis. This disease is transmitted by bite of infected squirrel (Xenopsylla cheopis). And it inhabits small rodents such as mice, voles and squirrels. Since bacteria are harmless to fleas, they are the best carriers to carry directly from animals to humans. When bacteria spread to the lungs, it is common for lung plague to occur when an infected person coughs or sneezes. It is rare, but it is considered a more serious form of plague, resulting in pneumonia, chest pain and the rapid onset of bloody or watery sputum. Pulmonary plague can cause respiratory failure and death usually within 36 hours if left untreated.

Pestop is one of the three plagues caused by Yersinia pestis. A symptom similar to influenza appears 1 to 7 days after being exposed to bacteria. These include fever, headache, vomiting. Swollen or painful lymph nodes appear in the area closest to the bacteria entering the skin. Occasionally swollen lymph nodes may burst. The three types of plague are the result of the infection route. Bubonic plague, septic plague, and pulmonary plague. Pest is spread mainly by fleas infected with small animals. It can also be caused by exposure to bodily fluids from plague-infected animals. In the acinar plague, the bacteria bite into the skin through the flea, enter the lymph nodes through the lymph duct, and inflate them. Diagnosis by finding blood, sputum or liquid bacteria from lymph nodes
