Two tests took, the Mantoux Test, inoculating .1cc of DPP in order to give a reading 48 hours later, taking as positives those that presented an indurate zone of 10 mm or more that means previous contact with this bacillus and obtaining from them 5 cc of venous peripheral blood in order to carry out the ELISA Test to detect latent Tuberculosis in blood, test that analyzes the presence of antibodies IgM and IgG against extracellular proteins of o o o Mycobacterium Tuberculosis. Among the study groups, those pertaining to 2 semester showed more contact with M. tuberculosis than those of 9 and 10 semesters when results were analyzed from groups F6, F7 and F8 where there are more students positive to the studied tests, this is equivalent to 29.3% and it indicates present infection. In conclusion, the students of recent entrance who gave positive to the tests, had previous contact in their environment which means they are immune resistant before Tuberculosis infection. Therefore, since there is no increase of positive IgM in the ninth and tenth semesters this indicates there does not exist any danger of infection during their professional development.
