TargetF15-+Inorganic+Pyrophosphatase+(Rickettsia+prowazekii)


 * *Target (protein/gene name): ** Inorganic Pyrophosphatase

***NCBI Gene # or RefSeq#:** 883528

***Protein ID (NP or XP #) or Wolbachia#:** NP_220958.1

***Organism (including strain):** //Rickettsia prowazekii//, str. Madrid E

**Etiologic Risk Group (see link below):** Category B priority pathogen, National Institute of Health

***/Disease Information (sort of like the Intro to your Mini Research Write up):** // Rickettsia prowazekii // is part of the family of //Rickettsia// bacteria, all of which are responsible for Typhus and different strains of spotted fever. //R. prowazekii// in particular is responsible for epidemic typhus fever, an infectious disease characterized by symptoms such as high fever, head aches, muscle aches, and fatigue. In severe cases, symptoms can even include life-threatening symptoms such as encephalitis or kidney failure. While epidemic typhus is most prevalent in the cold, mountainous, regions of Asia, Central Africa, South and Central America, infections have also been seen in the United States. In addition, //R. prowazekii// is a seen as a possible bioterrorism threat due to the risk for it to be contracted via inhalation in an aerosolized form. The bacterium is transmitted through the feces of human body lice, which have been infected with //R. prowazekii// after feeding on another individual infected with the disease. When the feces are pushed into the skin, through an open lesion such as the bite site, the bacteria are able to enter the body and cause infection.
