tuberculosis pathogenesis protection and control

Imagine a global emergency in the form of tuberculosis pathogenesis protection and control a re-emerging disease that is contagious; often fatal; increasingly resistant to antibiotics; with drug use, AIDS and alcohol abuse; among migrants and homeless people together from downtown; and acquired by simply breathing the air deadly pathogen.

These are the ingredients of an epic saga with sensational elements, in which the public reacts to panic, discrimination, prejudice and stigmatization of people living with the disease. The disease, which fits this description is tuberculosis, declared a global emergency by the World Health Organization (WHO) in 1993.

Acid-resistant rods found in a Peruvian mummy, about 700 AD and no sign of disease in the back of the pre-dynastic era figures (before 3000 BC) in Egypt, but tuberculosis was probably sporadically increased population density in a relatively short time. At its peak incidence in Europe in the 16th and 19th centuries, tuberculosis makes for a quarter of all deaths; India and sub-Saharan Africa, but the disease rarely by medical observers of the 19th century in Papua New Guinea has recognized TB has as late as 1950 recognized for the first area, as Western travelers explored in the Highlands.
CDC1551 strain of Mycobacterium tuberculosis, Mycobacterium tuberculosis, causes a local TB clinic miniepidemic (TB) in the region of the border between Kentucky and Tennessee (25). From 1994 to 1995, in a small rural community with a population with minimal risk for contracting TB, 21 patients were diagnosed with active TB. The source of the patient and the patient in the index have identified DNA restriction analysis and IS6110 pTBN12 fragment length polymorphisms. Under 429 contacts of TB patients, 72% had (often large) positive tuberculin reaction documented 20% conversion of the skin test. Only 3% of the tested were positive tuberculin noncontacts. These results imply that the CDC1551 strain is more virulent than other strains of tuberculosis, and studies in mice (25) also means that the most virulent.
Thus, with proper controls, the number of nodules visible five weeks after inhalation bacilli provides both a specific resistance of host and the virulence of bacilli (8, 16, 19, 19a) measurement. In addition (Table 1 and 2) provides tuber size and number of lung bacilli cultivation of them additional criteria to tuberculosis pathogenesis protection and control assess the virulence (host and acquired resistance).
