GEO 261 Study Guide - Midterm Guide: Septicemic Plague, Bubonic Plague, Pneumonic Plague
Document Summary
This study guide is designed to assist you in organizing your inquiry as to important points made in lectures. Zoonotic disease: what is the etiologic agent responsible for the plague. Pneumonic plague: less common, slightly higher mortality rate. Infected by inhaling infectious droplets or uncured bubonic plague. Septicemic plague: very rare, very high mortality rate. There have been several plague pandemics throughout history and each is associated with a specific form of the bacterium. When the y. pestis bacteria enter the body through the bite of an infected flea or through a (cid:272)ut or (cid:271)reak i(cid:374) the ski(cid:374), the resulti(cid:374)g disease is (cid:272)alled (cid:271)u(cid:271)o(cid:374)i(cid:272) plague. (cid:862)bu(cid:271)oes(cid:863) are s(cid:449)olle(cid:374) painful lymph nodes. Bubonic plague is the most common form of the disease and untreated it may progress to septicemic. When y. pestis bacteria accumulate in the bloodstream, septic shock occurs and the resulting disease is called septicemic plague.
