Ba. Hanna et al., RECOVERY OF MYCOBACTERIA FROM BLOOD IN MYCOBACTERIA GROWTH INDICATOR TUBE AND LOWENSTEIN-JENSEN SLANT AFTER LYSIS-CENTRIFUGATION, Journal of clinical microbiology, 33(12), 1995, pp. 3315-3316
Five hundred five blood samples for culture were processed in the Isol
ator lysis-centrifugatio system and were then inoculated into a Mycoba
cteria Growth Indicator Tube (MGIT) and onto a Lowenstein-Jensen (L-J)
slant. Forty-nine isolates of Mycobacterium avium complex and three i
solates of Mycobacterium tuberculosis were recovered from 50 of the bl
ood culture specimens. Forty-five isolates from 43 specimens were reco
vered in the MGIT, with a mean time to detection of 21 days. Forty-one
isolates from 40 specimens were recovered in the L-J slants, and the
mean time to detection was 36 days. Nine specimens were positive in th
e MGIT alone, while seven specimens were positive only in L-J medium.
