The entry of a microorganism into the general bloodstream leads to its spread throughout the body, which provides severe intoxication. The carrier of such a terrible disease is the plague bacillus - a bacterium belonging to the Enterobacteriaceae family. In order to develop under natural conditions, the plague bacillus had to adapt for a long time. This is due to the features of the growth and development of the microorganism, which.
Often, after infection with a bacterium, a bubonic type of disease occurs. In an infected person, a slight reddening occurs on the affected area, which quickly develops into a pustule, after opening an ulcer occurs. A week after communicating with the patient, there is a sudden fever, headache, weakness, chills, swollen lymph nodes, cough with sputum. This is the result of a flea bite. If the infected person does not take therapeutic measures on time, then the infection can spread to other parts of the body.
The skin over the seals becomes reddish and shiny. After 4 days, the inflammation becomes softer, when tapped, they move. After opening, fistulas are formed. From the first day, increased nervousness, severe muscle pain may begin. The following signs are also characteristic of the plague: the patient's face darkens, circles appear under the eyes, the tongue becomes coated, and the heart rhythm is disturbed. Black plague can be complicated by meningitis.
Plague pathogens enter the circulatory system through the skin, and after they enter the lymph nodes, primary inflammation begins. The incubation period is 3-6 days - this is the time required for the symptoms of the disease to begin to actively manifest. During an epidemic, the time is reduced to 1-2 days. The maximum incubation period is 9 days.
