Bubonic and septicemic plague are generally spread by When a flea bites a human and contaminates the wound with regurgitated blood, the plague-causing bacteria are passed into the tissue. It can be deadly if not treated promptly with antibiotics. The organism is transmitted to humans who are bitten by fleas that have fed on infected rodents or by humans handling infected animals.Known as the Black Death during medieval times, today plague occurs in fewer than 5,000 people a year worldwide. Experiments included various delivery methods, vacuum drying, sizing the bacterium, developing strains resistant to antibiotics, combining the bacterium with other diseases (such as The plague can be easily treated with antibiotics. If the lymph node is overwhelmed, the infection can pass into the bloodstream, causing Lymphatics ultimately drain into the bloodstream, so the plague bacteria may enter the blood and travel to almost any part of the body. Plague, caused by bacteria and transmitted through flea bites and infected animals, killed an estimated 50 million people in Europe during the Black Death pandemic in the Middle Ages.
