The main objective of this research was to evaluate operationally baciloscopy using Polimerase Chain Reaction of for tuberculosis (TB- PCR). It was evaluated 144 sputum samples obtained from Direccion de Salud Lima Este. To all the samples they were practiced baciloscopy using the classical technique of Ziehl-Neelsen, which was verified with the Ogawa cultivation and the slides were evaluated with TB PCR using the insertion sequence IS6110. After the amplification it was obtained a fragment of 123 couples of bases corresponding to the sequence of insertion IS6110. Of the total of samples examined by the Ziehl-Neelsen method, 54 were positive and 90 were negative (37.5% and 62.5% respectively). In the same samples tested using TB PCR, 67 were positive (46.5%) and 77 were negative (53.4%); while for cultivation test 66 were positive and 78 negative (45.8% and 54.2% respectively). The routine bacteriological procedures (direct exam and cultivation) can be a very powerful tool for the diagnosis of lung tuberculosis and other mycobacterium diseases; but there is a significant understimate on all TB cases, especially using the Classical Ziehl Neelsen staining when it is evaluated with TB-PCR as reference.
