Mtp-40 and alpha antigen gene fragment amplification for the detection of Mycobacterium tuberculosis in Colombian clinical specimens
In this study, the use of Mtp-40 and alpha antigen polymerase chain reaction (PCR) amplification fragments for the precise tuberculosis (TB) diagnosis was evaluated. One hundred and ninety two different samples were obtained from 113 patients with suspected TB. Mtp-40 and alpha antigen protein genes were amplified by the PCR technique and compared to both the "gold standard" (culture) test, as well as the clinical parameters (including a clinical record and X-ray film exam in 113 patients). Thirty-eight of the 113 patients had a presumptive clinical diagnosis of TB; 74% being detected by PCR technique, 58% by culture and 44% by direct microscopic visualization. Weconclude that it is possible to use PCR as a suitable technique for the detection of any mycobacteria by means of the alpha antigen product, or the specific infection of Mycobacterium tuberculosis by means of the mtp-40 gene. This might be a good supporting tool in difficult clinical TB diagnosis and pauci-bacillary cases

ADAPTACIÓN DE LA CEPA MUNANTA DE TRYPANOSOMA CRUZI AL CULTIVO IN VITRO EN CÉLULAS VERO
The importance of obtaining the different stages of Trypanosoma cruzi in order to recognize the antigens involved in the intracellular invasion and replication processes, makes it necessary to adapt these strains to tissue culture, especially considering the high leve! of biological, biochemical and genetic variation, which is found among the strains and clones ofthe parasite. Within the aforementioned context, in this study, the Colombian strain ofT. cruzi, M un anta, was adapted to tissue culture in Yero Cells, obtaining the principal forms ofthe parasite: trypomastigotes, amastigotes and epimastigotes. lt was observed that the liberation of the trypomastigotes occurred on the seventh day postinfection and the quantity obtained was directly proportional to the number of infecting parasites. On the other hand, the majority of the trypomastigotes observed 48 hours after washing the monolayer five days after infection, were had thick-looking shapes corresponding to the initiation ofthe trasforrnation from trypomastigotes to amastigotes
