Document Summary

Bios 111 disease of the day - rickettsias lecture 26 (3/15/17) Intracellular parasites but they are indeed bacteria. Mostly steal atp from the host cell instead of making their own. This is how they are intracellular parasites. Interferons are some of the only drugs effective against viruses. Louse/lice are infected by the rickettsia so when they bite the human they inject it into the human blood. The bacteria lives in the blood stream and destroys cells. The dead cells then flood into the veins and arteries. Causes the veins and arteries to collapse. In rocky mountain spotted fever the vector is ticks. Napoleon had a huge army but they started dying to down to just 20,000 from typhus moreso than military combat. They occupied russian camps that had lots of lice so they started dying from typhus. They then (survivors) spread the lice throughout europe. In the crimean war, 2,000 died in battle and 50,000 died from disease.
