Yersinia Pestis is a gram-negative bacillus that it not motile and has bipolar staining. Although is usually transmitted to humans through a flea bite from a flea that previously fed on an infected rodent. It can be transferred to humans in three known ways. First is mentioned above with a flea bite by an affected flea. Second is through contact with contaminated fluid or tissues of an infected animal. The most common way is when hunters skin or consume animals with the bacteria without taking proper precautions resulting in bubonic or septicemic plague. The last way humans can be infected is through contact with infected droplets. It can be transferred pneumatically in rare cases when the bacteria relocates to the lungs through the blood stream. When a person with pneumonic plague coughs, they release bacteria filled droplet into the air. If an unsuspecting person inhales these droplets they can be overcome with pneumonic plague, although this type of transmission requires close and direct contact with a person infected with pneumonic
