Causes
Yersinia pestis, a rod-shaped facultative anaerobe with bipolar staining (giving it a safety pin appearance).[1] causes the infection in mammals and humans.
Transmission of Y. pestis to an uninfected individual is possible by any of the following means.[2]
- droplet contact – coughing or sneezing on another person
- direct physical contact – touching an infected person, including sexual contact
- indirect contact – usually by touching soil contamination or a contaminated surface
- airborne transmission – if the microorganism can remain in the air for long periods
- fecal-oral transmission – usually from contaminated food or water sources
- vector borne transmission – carried by insects or other animals.
