Product Summary: «

From 1985 to 1992, the number of MTB cases reported increased 18%. Tuberculosis still kills an estimated 3 million persons a year worldwide, making it the leading infectious disease cause of death.1 Between 1981 and 1987, AIDS case surveillances indicated that 5.5% of the patients with AIDS had disseminated nontuberculous mycobacterial infections, e.g., MAC. By 1990, the increased cases of disseminated nontuberculous mycobacterial infections had resulted in a cumulative incidence of 7.6%.2 In addition to the resurgence of MTB, multidrug-resistant MTB (MDR-TB) has become an increasing concern. Laboratory delays in the growth, identification and reporting of these MDR-TB cases contributed at least in part to the spread of the disease.3

The U.S. Centers for Disease Control and Prevention (CDC) have recommended that every effort must be made by laboratories to use the most rapid methods available for diagnostic mycobacteria testing. These recommendations include the use of both a liquid and a solid medium for mycobacterial culture.3

The MGIT Mycobacteria Growth Indicator Tube contains 4 mL of modified Middlebrook 7H9 Broth base.4,5 The complete medium, with 0.5 mL OADC enrichment and 0.1 mL of PANTA antibiotic mixture, is one of the most commonly used liquid media for the cultivation of mycobacteria.

All types of clinical specimens, pulmonary as well as extra-pulmonary (except blood and urine), can be processed for primary isolation in the MGIT tube using conventional methods.6 The processed specimen is inoculated into a MGIT tube, incubated and read daily from the second day of incubation using a longwave UV light. At the time of tube positivity, there are approximately 104 – 107 CFU/mL of mycobacteria present.

User Quality Control: « User Quality Control:

Upon receipt of a new shipment or lot number of MGIT tubes, it is suggested that suspensions of the ATCC control organisms be prepared in Middlebrook 7H9 Broth.

1. From solid media cultures less than 15 days old, prepare a suspension in Middlebrook 7H9 Broth.
2. Allow the suspension to sit for 20 min.
3. Transfer the supernatant to an empty, sterile tube and allow to sit for an additional 15 min.
4. Transfer the supernatant to another empty, sterile tube.
5. Using a nephelometer, adjust the suspension to a turbidity comparable to a 0.5 McFarland standard.
6. Dilute the control organism suspensions following the dilution scheme outlined in Table 1.
7. Inoculate the MGIT tubes following the "Inoculation of MGIT Tubes" procedure.

The MGIT tubes should show fluorescence within the time frame shown in Table 1.

At the time of tube positivity, there are approximately 104 – 107 CFU/mL of mycobacteria present. If the QC MGIT tubes do not give the expected results, do not use the remaining tubes until you have contacted Technical Services at (800) 638-8663 (United States only).

Warnings and Precautions: « Warnings and Precautions:

For in vitro Diagnostic Use.

Pathogenic microorganisms including Hepatitis B Virus and Human Immunodeficiency Virus may be present in specimens. "Universal Precautions"1,2 should be followed in handling all items contaminated with blood or other body fluids.

Working with Mycobacterium tuberculosis grown in culture requires Biosafety Level 3 practices, containment equipment and facilities.6

Prior to use, each MGIT tube should be examined for evidence of contamination or damage. Discard any tubes if they appear unsuitable or exhibit fluorescence prior to use.

Dropped tubes should be examined carefully. If damage is seen, the tube should be discarded.

Wear UV protective glasses when observing fluorescence and use only longwave illumination (365 nm). DO NOT USE SHORTWAVE UV LIGHT FOR READING TUBES.

Autoclave all inoculated MGIT tubes prior to disposal.
