Material and Methods: A total of 4237 specimens were evaluated in the study for the results of microscopic examination and culture. Of 4237 specimens, 2719 were obtained from respiratory tract and remaining 1518 were obtained out of the respiratory tract. Results: According to the results of culture. Mycobacterium tuberculosis complex were isolated in 271 (6.4%) specimens on BACTEC 460TB system and in 238 (5.6%) specimens on Lowenstein Jensen medium. Contamination rates at BACTEC 460TB system and Lowenstein Jensen medium were 3.6% and 10.2%, respectively. The mean times of recovery were determined as 9.6 days for BACTEC system and 21 days for Lowenstein Jensen medium. When contaminated specimens were excluded, Mycobacterium tuberculosis was grown on at least one culture technique in 258 out of 3718 (6.9%) specimens. Sensitivity of BACTEC 460 TB culture system was found as 96%, while sensitivity of Lowenstein Jensen medium was found as 92%. The correlation between two culture techniques was found as 99%. Contribution of BACTEC 460 TB system and LJ medium alone to culture positivity were found as 8.3% and 3.9% respectively. No statistically significant difference was found when microscopic evaluation and culture systems were compared. Conclusion: It was concluded that the liquid culture systems are needed for rapid detection of tuberculosis, however liquid and solid culture systems should be used together in order to reach maximum isolation rates.TurkishMGIT 960 SYSTEMMYCOBACTERIUM-TUBERCULOSISSOLID MEDIATBSPECIMENSRECOVERYSUSCEPTIBILITYArticle
