[Application of rapid detection for Mycobacterium tuberculosis with phage splitting assay].
OBJECTIVE
To study the significance of rapid identification for Mycobacterium tuberculosis with phage splitting assay.


METHODS
Strains of Mycobacterium tuberculosis, non-tuberculosis mycobacterium, non-mycobacterium and samples of sputum with pulmonary tuberculosis were rapidly detected by phage spot technique.


RESULTS
The strains of Mycobacterium tuberculosis H37Rv, bovis and africanum were all positive. The results of 10 strains of non-tuberculosis mycobacterium and 7 strains of non-mycobacterium were negative. All of 30 clinical isolates from the patients of the pulmonary tuberculosis were positive. 19 of 20 sputum specimen of pulmonary tuberculosis, which were all positive detected by smear and culture, were positive. There were 15 specimen positive in 21 sputum with negative tested by smear and positive by culture. Besides, 5 of 19 sputum specimen with negative by smear and culture were positive detected by this method.


CONCLUSIONS
The phage splitting assay can be used for rapid identification of Mycobacterium tuberculosis, which possesses high specificity and sensitivity for detection of Mycobacterium tuberculosis in sputum specimen.
