[Culture based diagnostic methods for tuberculosis].
Culture methods providing isolates for identification and drug susceptibility testing, still represent the gold standard for the definitive diagnosis of tuberculosis, although the delay in obtaining results still remains a problem. Traditional solid media are recommended for use along with liquid media in primary isolation of mycobacteria. At present, a number of elaborate culture systems are available commercially. They range from simple bottles and tubes such as MGIT (BD Diagnostic Systems, USA), Septi-Chek AFB (BD, USA) and MB Redox (Biotest Diagnostics, USA) to semiautomated system (BACTEC 460TB, BD, USA) and fully automated systems (BACTEC 9000 MB [BD, USA], BACTEC MGIT 960 [BD, USA], ESP Culture System II [Trek Diagnostics, USA], MB/BacT ALERT 3D System [BioMérieux, NC], TK Culture System [Salubris Inc, Turkey]). Culture methods available today are sufficient to permit laboratories to develop an algoritm that is optimal for patients and administrative needs. In this review article, the culture systems used for the diagnosis of tuberculosis, their mechanisms, advantages and disadvantages have been discussed under the light of recent literature.
