Virulence characteristics, unique properties, and diseases caused by: Mycobacterium tuberculosis, - -virulent strains contain cord factor (cell wall component) which is necessary to cause disease -3 types: primary (results from initial infection), secondary (reestab. of active infection after period of dormancy), disseminated (when infection spreads thru body) -high risk ppl are those who contact infected persons and those with immunodeficiencies (HIV--combo has 90% chance of death) -diagno...
