Plagues and People Chapter 13: The Peoples Plague: Tuberculosis: Disease is also called consumption; con meaning completely and sumere meaning to take up. More commonly called tuberculosis, TB, or the white plague 1800s when epidemic TB reached its peak in Western Europe, they were considered beautiful and erotic. TB is a chronic infectious disease that was romanticized. Tuberculosis of the lungs called pulmonary TB is given a slang word called lunger. When localized in the lungs tuberculosis can run an acute course, causing major destruction in a few months. Potts disease after sir Percival Pott causes deformation of the spine, described in 1779. Lead to hunchback and also affect the skin and the kidneys. Tb of adrenal cortex destroys the adrenal function and results in Addisons disease. Microbes that cause TB are called mycobacteria; their free-living relatives inhabit the soil and water. Have a protective cell wall, rich in unusla waxy lipids, such as mycolic acid and polysaccharides. M. Tuberculosis. M. Leprae and M. avium are human pathogens that cause TB, leprosy and pulmonary disease. M. avium is in opportunistic infection; weight loss, fevers, chills, night sweats, abdominal pains, diarrhea, and overall weakness M. bovis; can infect people by infrequently and great difficulty. Grows under conditions where oxygen levels are low, not associated with lung disease M. tuberculosis grows best when oxygen is plentiful and is associated with pulmonary TB. Tb of the spine is associated with M. Bovis, and results form a blood infection that spreads to the spin from the lymph vessels. Hypothesized that we were infected with M. bovis by drinking milk. M. tuberculosis is specific to humans and spread form person o person through droplets of saliva and mucus. Potts disease has been described in Egyptian mummies from 3700 BC to 1000 BC But TUB of the lungs has been found more recently than the other bones, from 1000 BC to 400 BC www.notesolution.com
