Transmition of tuberculosis between man and livestock is quite common. In the world tuberculosis is described
to be present in 20 million people. and every year 5 million people is added to this fgure. People living in poorer
areas are more in danger of the tuberculosis. Tuberculosis has been diagnosed in cows with dilapidated tubercles
in various organs. In addition to the cow, man, goats and pigs are sensitive to bovine tuberculosis, sheep and horses
show a kind of natural resistance.
Three types of Mycobacterium tubercule bacilli have been recognized among warm blooded animals , which
human tuberculosis species (Mycobacterium tuberculosis) and bovine species (Mycobacterium bovis) are very
similar to each other but a kind of chicken species is different.
Identifcation of different mycobacterial species with biochemical and phenotypic methods is time-consuming
and diffcult, and using these diagnostic methods created some problems to identify some of these species. Today
rapid molecular diagnostic methods for mycobacterial species which infected human communities have important
position in epidemiology and control of tuberculosis. Therefore, the recognition of the strain types in every region
reveals the usefull information about the disease for every society. This issue in identifying all cases infected with
the mycobacterial strains (Atypical and TB) is very important.
Recently some techniques such as Restriction Fragment Length Polymorphism (RFLP) and the use of specifc
probes in the diagnosis of mycobacterial strains have much effciency. By using these methods one can easily take
samples from suspicious humans or animals and in one mycobacterial infection and species identifcation can be
performed. It is obvious that quick diagnosis of mycobacterial infections can help to reduce the disease in the
