Is plague aerobic?
Yersinia pestis, the causative agent of plague, is a pleomorphic, gram negative coccobacillus in the family Enterobacteriaceae. It is an aerobic, facultatively anaerobic, and facultatively intracellular pathogen.
Who or what does the Yersinia pestis usually infect?
Y. pestis primarily infects small ground-dwelling mammals, specifically of the taxonomic order Rodentia, but maintains high spillover potential to other vertebrates, including humans, caused by its high virulence and fleaborne transmission.
How many people died from Yersinia pestis?
The organism Yersinia pestis is responsible for the plague, a disease that has an extremely important place in human history. During the 6th century AD, the plague ravaged the known world over a 50 year period causing 100 million deaths.
Does Yersinia pestis have a flagellum?
It is hypothesised that the flagellum evolved from the type three secretory system. For example, the bubonic plague bacterium Yersinia pestis has an organelle assembly very similar to a complex flagellum, except that is missing only a few flagellar mechanisms and functions, such as a needle to inject toxins into other cells.
What are the symptoms of Yersinia pestis?
Bubonic plague is the most common primary manifestation of Yersinia pestis infection with patients developing sudden onset of fever, headache, chills, and weakness and one or more swollen, tender and painful lymph nodes (called buboes ). A bubo usually occurs in the groin, armpit or cervical lymph nodes.
