Taking a Look at the Bubonic Plague

Task 1 Tuberculosis is caused by gram-negative bacteria that infect humans and other animals, bacteria called Yersinia pestis. This is a very contagious disease. The main form of infection is that fleas are carried by rodents, as fleas pass bacteria through the barrier of the skin, and depending on the sanitary condition of the area, they also go through direct contact and contaminated food. spread. . Infection is achievable because bacteria can inhibit or even prevent normal immune responses against foreign bacteria such as phagocytosis and antibody production.

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

The general form of plague is the most common form of plague. It usually occurs after infected flea bites. The main feature of the glandular plague is swollen, painful lymph nodes, usually in the groin, armpits, or neck. Other symptoms include fever, chills, headaches and extreme fatigue. People usually suffer from plague 1 to 6 days after infection. Failure to treat early may spread bacteria to other parts of the body, causing sepsis or pulmonary plague.

Three main forms of plague are generally described, including glandular plague, pneumonia, and septicemia (7). Yersinia pestis, however, can be used not only through flea bite (causing plague) and respiratory droplets (causing plague), but also eating uncooked contaminated meat (causing gastrointestinal plague) and infected pets / It also spreads by contact with livestock (causing conjunctivitis, skin pest or pulmonary plague) (12). In addition, plague pharyngitis, meningitis, and endophthalmitis have been reported, but rare (13). If the plague is not treated unspecified, it may develop pulmonary plague or systemic plague (septicemia) by spreading the plague in the blood. This type of plague mortality is very high (7). Septic plague can also be caused directly by cutting blood infections causing pathogens.
