   hypercubic group. The demipenteract, with one hundred and twenty cells, is the only fifth-dimensional semiregular polytope, and has the rectified 5-cell as its vertex figure, which is one of only three semiregular 4-polytopes alongside the rectified 600-cell and the snub 24-cell. In the fifth dimension, there are five regular paracompact honeycombs, all with infinite facets and vertex figures.
Septicemic plague is one of the three forms of plague, and is caused by Yersinia pestis, a gram-negative species of bacterium. Septicemic plague is a systemic disease involving infection of the blood, and is most commonly spread by bites from infected fleas. Septicemic plague can cause disseminated intravascular coagulation, and is almost always fatal when untreated. The other varieties of the plague are bubonic plague and pneumonic plague. Signs and symptoms
The usual symptoms are:
Abdominal pain
Bleeding under skin due to blood clotting problems
Bleeding from mouth, nose or rectum
Gastrointestinal symptoms, including nausea, vomiting, which can be with blood, and diarrhea
Fever
Chills
Low blood pressure
Organ failure
Shock
Death of tissue (gangrene) in extremities, mostly fingers, nose, and toes
Difficulty breathingThese symptoms are common to many human illnesses, and are not considered, in and of themselves, to signify infection with any form of plague.It is important to note that septicemic plague may be asymptomatic, and may cause death absent of any symptoms. Cause
Transmission
Human Yersinia infections most commonly result from the bite of an infected flea or occasionally an infected mammal, but like most bacterial systemic diseases, the disease may be transmitted through an opening in the skin or by inhaling infectious droplets of moisture from sneezes or coughs. In both cases septicemic plague need not be the result, and in particular, not the initial result, but it occasionally happens that bubonic plague for example leads to infection of the blood, and septicemic plague results.
