Mycoplasma tuberculosis Gram stain

Mycobacterium tuberculosis (MTB) is a pathogenic bacterial species in the Mycobacteriaceae family, Mycoplasma tuberculosis Gram stain and is the cause of most cases of tuberculosis (TB). [1] First discovered in 1882 by Robert Koch, M. tuberculosis, a rare waxy coating on the cell surface (largely due to the presence of mycolic acids), cells that are resistant to Gram staining.

Ziehl-Neelsen staining or acid is used instead. The physiology of M. tuberculosis intense and requires a high level of oxygen. Primarily a disease of the respiratory tract in mammals, MTB infects the lungs. Diagnostic methods most commonly used for tuberculosis are radiographs tuberculin skin test, acid-fast staining and chest.
Tuberculosis (TB) is the leading cause of death worldwide from a bacterial infectious disease. The disease affects 1.8 billion people / year,. Equal to one third of the world total

Mycoplasma tuberculosis Gram stain

In the United States, TB is on the decline. In 2007, 13,293 cases were reported in total. TB dropped to 4.4 cases per 100,000 population, the lowest rate recorded since national reporting began in 1953 Despite this overall improvement, progress towards TB elimination slowed in recent years; The average annual decline in percent in the TB rate slowed to 7.3% per year during 1993-2000 to 3.8% in 2000-2007. There was a gradual decrease in the number of TB patients co-infected with HIV and the number of MDR-TB cases has gradually declined. Also since 1993

On the other hand, the proportion of TB cases born abroad individuals intake has increased since 1993 In 2007, the rate of TB among foreign-born persons in the United States with 9.7 times higher than American-born people annually. In many countries, particularly in the West, Midwest and Northeast, most new cases of TB among foreign-born persons occur now.
Lowenstein-Jensen Mycobacterium tuberculosis medium after 6 weeks of culture at 37 ° C. The typical eugonic growth on Lowenstein-Jensen: buff yellow, wrinkled rough colonies. The green color of the media due to the presence of malachite green, which to avoid. Selection means for the growth of most other contaminants Mycoplasma tuberculosis Gram stain Unlike many others in clinical microbiology Lowenstein-Jensen (or ex Ogawa medium) do not use agar containing a solid nutrient medium (hard consistency obtained by heat coagulation of egg albumin).
