Abstract
The aim of this study was to perform a literature review about the frequency of ethambutol resistance in cases or samples by Mycobacterium Tuberculosis. A research protocol was formalized and executed to conduct the search in the PubMed database during July 2019 and September 2019, with articles published between 2014 and 2019. The results obtained were analyzed and incorporated into the present study from inclusion and exclusion criteria set out in the protocol. Thus, we sought to elucidate about the frequency of tuberculin resistance to ethambutol and as a result we found a low frequency of resistance to the drug in question in relation to the other drugs established as first line, according to the study site, for the treatment of Tuberculosis.
