Product Summary: «

Mycobacteria are infectious agents responsible for persistent and chronic clinical conditions most commonly of a respiratory nature, and some are spread by coughing and expectoration.1,2 As a group, these organisms are capable of infecting nearly every organ of the body. This has become increasingly evident and frequent in cases of underlying immune dysfunction associated with conditions such as HIV infection and drug abuse.3,4

Historically, the most frequently encountered human pathogenic Mycobacterium is M. tuberculosis.1,2 In some populations, this has been exceeded by the Mycobacterium avium complex.3,4

The mycobacteria have several characteristics which distinguish them from other bacteria. The most notable of these are resistance to decolorization after staining, relatively slow growth, and resistance to digesting agents.5 Conventional culture media used for mycobacteria isolation are most often Lowenstein-Jensen (LJ), or Middlebrook 7H9, 7H10 or 7H11.6 Growth in these media is observed in a range of 3 – 56 days, depending on the species isolated and concentration of viable bacteria. The SEPTI-CHEK AFB system is designed to promote rapid growth in a broth medium, while providing simultaneous subculture on three different media, a presumptive identification, and the ability to perform identification and susceptibility testing.

User Quality Control: « User Quality Control:

Test procedures for the SEPTI-CHEK AFB Mycobacteria Culture Bottle with supplement added, and the SEPTI-CHEK AFB Slide have been prepared in compliance with National Committee for Clinical Laboratory Standards (NCCLS) Vol. 5, No. 20, Quality Assurance for Commercially Prepared Microbiological Culture Media.

Upon receipt of a new shipment or lot number, one of the following organisms is recommended for inoculation of SEPTI-CHEK AFB Mycobacteria Culture Bottle or SEPTI-CHEK AFB Slide at 104 CFU/bottle:

a)
  M. tuberculosis  ATCC®   25177
  M. kansasii   ATCC   12478
  M. scrofulaceum  ATCC   19981
  M. intracellulare  ATCC   13950
  M. fortuitum  ATCC   6841

and one of the following organisms is recommended for inoculation at 105 CFU/bottle:

b)
  Escherichia coli  ATCC   25922
  Streptococcus pneumoniae  ATCC   6305
  Staphylococcus aureus  ATCC   25923

The growth in the bottle of the (a) group is checked after 21 and 28 days at 37°C with the following anticipated results:
(+) = Weak Growth.
+ = Moderate-Strong Growth.

Growth After
Mycobacterium 21 Days 28 Days
M. tuberculosis + +
M. kansasii + +
M. scrofulaceum (+) (+)
M. intracellulare (+) (+)
M. fortuitum + +

Growth of the (a) group on slides should be observed after 21 days with the following expected results:
+ = Growth.
- = No Growth.

MycobacteriumSide 1: 7H11Side 2: EggSide 3: Choc.
M. tuberculosis + + +/-
M. kansasii + + +/-
M. scrofulaceum + + +/-
M. intracellulare + + -
M. fortuitum + + +/-

The (b) group should show no or weak growth in the bottle after 7 days at 37°C.

If the SEPTI-CHEK AFB Mycobacteria Culture Bottle with supplement added or the SEPTI-CHEK AFB Slide do not give the expected results, do not use the media until Technical Services (U.S.A.) has been contacted, 1-800-638-8663.

Warnings and Precautions: « Warnings and Precautions:

in vitro Diagnostic

As with any diagnostic procedure, clinical considerations and professional judgement should be used in interpreting any test result, particularly a single test result.

The SEPTI-CHEK AFB System is intended for use in laboratories experienced in handling mycobacteria or mycobacteria-containing specimens.7 Since M. tuberculosis is highly infectious, specimens and SEPTI-CHEK AFB components should be handled by qualified personnel in compliance with "Universal Precautions"8 and institutional guidelines. Bottles and slides should be autoclaved prior to being discarded.
