ABSTRACT
Objective To evaluate the BacT/ALERT 3D liquid rapid culture system for the rapid detection of mycobacterium tuberculosis(MTB)and early diagnosis of pulmonary tuberculosis.Methods BacT/ALERT 3D liquid culture mediums and lowenstein-jensen(L-J)solid culture mediums were applied to detect Mycobacterium tuberculosis sputum specimens respectively.Analysis of detection results and detection time were also performed.Results Average positive days of BacT/ALERT 3D liquid culture medium was(13 ±2.05)days,which was shorter than that of L-J solid culture mediums(34.7 ±4.76 )d (P<0.05 ).Compared to the L -J solid culture mediums,BacT/ALERT 3D liquid culture medium had higher positive rate for 59 patients whose sputum smear test was positive,and the positive rate were 71.18%(42/59)and 67.80%(40/59)respectively(P<0.05).BacT/ALERT 3D liquid culture medium had higher positive rate than L-J solid culture mediums for 106 patients whose sputum smear test was negative,and the positive rate were 39.62%(42/106)and 26.42%(28/106)respectively(P<0.05).Conclusion Compared to the traditional L-J solid culture system,BacT/ALERT 3D liquid culture system can shorten detection time and improve the positive detection rate of MTB in specimens with low concentration.
