Determination of MICs for Mycobacterium avium-M. intracellulare complex in liquid medium by a colorimetric method.
We investigated the potential of a rapid colorimetric microassay based on the reduction of dimethylthiazol-diphenyltetrazolium bromide (MTT) for determining the growth of Mycobacterium avium-M. intracellulare complex (MAC) and MICs of clofazimine, resorcinomycin A, and the quinolone PD 127391 against MAC. The reduction of MTT was directly proportional to the number of viable bacteria. A compari...
متن کاملMycobacterium Avium-intracellulare Sinusitis.
M ycobacterium avium-intracellulare (MAI) sinusitis is rarely diagnosed. There are only nine previous cases documented in the literature, most of which are in patients with acquired immune deficiency syndrome (AIDS). Awareness of MAI sinusitis may prove valuable to the practicing otolaryngologist, and an elevated index of suspicion is necessary in all immunocompromised patients with sinusitis, ...
متن کاملSelective medium for the isolation and enumeration of Mycobacterium avium-intracellulare and M. scrofulaceum.
A medium for the selective isolation and enumeration of Mycobacterium avium-intracellulare and M. scrofulaceum (MAIS) was developed, based upon the ability of these mycobacteria to utilize Tween 80 as sole carbon source and grow optimally at pH 5.5 on a simple mineral salts medium. Representative MAIS strains had higher efficiencies of plating on the Tween 80 medium compared with Middlebrook 7H...
متن کاملOptimum recovery of Mycobacterium avium complex from blood specimens of human immunodeficiency virus-positive patients by using small volumes of isolator concentrate inoculated into BACTEC 12B bottles.
Recovery of Mycobacterium avium complex organisms from 412 lysis-centrifugation (Isolator) concentrates of blood specimens obtained from human immunodeficiency virus-positive individuals was attempted with the following media (and Isolator concentrate inoculum volumes): BACTEC 12B broth (0.2 and 1.0 ml), Lowenstein-Jensen slants (0.1 ml), and Middlebrook 7H10/11 agar (0.1 ml). A total of 42 M. ...
متن کاملArylsulfatase activity for differentiating Mycobacterium avium and Mycobacterium intracellulare.
Arylsulfatase activities (96-h reaction) of various strains of Mycobacterium avium and M. intracellulare, as identified by a DNA probe test, were measured. The enzyme activities of M. avium strains were significantly lower [corrected] than those of M. intracellulare strains (P less than 0.005 to P less than 0.025). The enzyme activities did not vary with serovar; that is, the activities of sero...
