Flu Facts
Every year in the United States, on average:
Mycobacterium tuberculosis - MDR-TB and XDR-TB strain, Gram-positive, rod prokaryote. M. tuberculosis is a zoonotic microorganism - i.e. its host is domestic animals. Contaminated respiratory secretions transmit the infection to humans, causing tuberculosis (TB). In the past few years drug resistant strains, MDR-TB and XDR-TB strains have emerged, especially in developing countries. MDR-TB (Multidrug Resistant TB) are strains of tuberculosis that are resistant to at least the two first-line TB drugs - isoniazid and rifampicin. XDR-TB, or Extensive Drug Resistant TB (also known as Extreme Drug Resistance) is a MDR-TB strain that is also resistant to three or more of the six classes of second-line drugs. Drug resistant tuberculosis is transmitted in the same way as regular TB. Drug-resistant TB is a public health issue in many developing countries, as treatment is longer and requires more expensive drugs. XDR-TB poses a severe public health crisis, especially in populations where HIV is prevalent and where there are few health care resources.
