**6. Conclusion**

Limited healthcare and economic resources, inadequate exposure to anti tuberculosis drug regimens and specific characteristics of the infected host, have paved the long way to the genetic inheritance of resistant strains of tuberculosis to develop and propagate in this side of the world. Migratory patterns from Europa and Asia to the Latin American territories have brought tuberculosis strains with genes capable of resists specific drugs, but it has been the inadequate use of medication and the exposures in these lands that have allowed the genetic transformation of bacteria in the populations. As Peru did in decade of 1990, establishing direct observation therapy programs help significatively to decrease the prevalence of MDR-TB strains in the population [14]. Also, prevention of TB spread with rapid diagnosis and screening in high risk populations is a pivotal way to decrease the surge of new cases. The global use of the new genetic rapid tests for detecting drug resistant strains of TB [4] is another way for eradication of MDR-TB. Most important, is to increase population's access to appropriate therapy for those with sensitive and resistant TB infections.

The reach for better healthcare systems, population awareness, programs for better screening and assurance of adequate treatment for tuberculosis patients will be the only infallible tool to decrease the rate of MDR-TB infections and the way to achieve eradication.
