    • "Drug-resistant TB is transmitted in the same way as drugsusceptible TB, and is no more infectious than drug-susceptible TB. However, delay in the recognition of drug resistance or prolonged periods of infectiousness may facilitate increased transmission and further development of drug resistance[1]. Multidrugresistant TB (MDR TB) is caused by organisms resistant to the most effective anti-TB drugs, isoniazid and rifampin. "

A descriptive study was design. The data were collected from different hospitals located in different area of district Dir (L). The data were analyzed for area wise distribution, area wise comparison, gender wise distribution and comparison and age wise distribution. From January 2011 to December 2011 total 1332 sample populations were analyzed. Out of total samples the 513 (38.51%) were positive and 819 (61.49%) were found negative.

    • "Except for Mycobacterium leprae, which does not grow in vitro, those species were classified in two distinct groups: species that belong to the Mycobacterium tuberculosis complex (MTC), and nontuberculous mycobacteria (NTM) [1] [2] Mycobacterium tuberculosis infects over one-third of the human population worldwide, causing nine million new cases of tuberculosis and two million deaths annually [3]. While members of the MTC cause more disease worldwide than any other bacteria [4], NTM are widespread in nature and, with some significant exceptions, are free-living saprophytes and opportunistic pathogens. Although considered to be non-pathogenic, NTM can pose a threat to humans, mainly in patients with underlying conditions such as AIDS or cancer, and there is an increasing awareness of their public-health importance, especially as nosoco‐ mial pathogens [5].
