| molecular features of mycobacterium avium human isolates carrying a single copy of is1245 and is1311 per genome. | human clinical isolates of the mycobacterium avium complex, from hospitals in bogotá, were studied using a wide range of molecular tests including pcr restriction-enzyme analysis (pra) of the hsp65 gene. up to 21 of the isolates were identified as m. avium pra variant iii (mav iii), a variant obtained only from isolates on the american continent. in contrast to previous reports, restriction fragment length polymorphism analysis using is1245 and is1311 showed a single copy for each insertion sequ ... | 2007 | 17559402 |
