Tuberculosis is devastating disease at global level. TB is caused by members of Mycobaterium tuberculosis complex group. Presently available biochemical methods of diagnosis of tuberculosis are not accurate. The highly sensitive polymerase chain reaction (PCR) and specific molecular probes techniques are major advances in early diagnosis and molecular epidemiology of various diseases including TB. It is established that the ribosomal gene region of both the prokaryotic and eukaryotic comprise of sequences that are conserved during evolution interspersed with sequence which are divergent. The...
