VersaTREK® Mycobacteria Detection & Susceptibility Testing
Redefining Mycobacterium Detection and MYCO TB Susceptibility Testing
- Reliably detects a wide variety of mycobacteria species from ALL specimen types
- The only system with a simplified media format allows culturing of ALL specimens
in one bottle type
- Ability to perform additional confirmatory tests directly from the culture bottle,
including smears, subcultures and direct DNA probes, user-friendly and saves time!
- VersaTREK REDOX 1 and VersaTREK REDOX 2 media uses dilution and timing to detect microbes
instead of costly specialized additive media
- Unique growth matrix, via the addition of distinctive cellulose sponge material
in the myco bottles, provides better recovery of ALL Mycobacteria species
- High bottle throughput, permits capacity of 4,600 samples in a single VersaTREK 528 model*
* Based on a 42-day protocol at 100% capacity.

Mycobacteria Detection and Susceptibility Testing Using VersaTREK
VersaTREK detects mycobacterial growth by automatically monitoring (every 24 minutes)
the rate of oxygen consumption within the headspace of the culture bottle. A positive
growth response is reported via a visible and audible positive signal by the system.
VersaTREK combines a liquid culture medium (VersaTREK Myco Broth), a growth
supplement (Myco GS), and, for potentially contaminated species, an antibiotic supplement
(Myco AS or Myco PVNA*), with a detection system that automatically incubates and
continuously monitors culture bottles inoculated with specimens possibly containing
mycobacteria.
VersaTREK Myco Susceptibility Kit
The VersaTREK Myco Susceptibility Kit consists of three primary antituberculosis
drugs – Rifampin (1 µg/ml), Isoniazid (0.4 µg/ml and 0.1 µg/ml),
and Ethambutol (8 µg/ml and 5 ug/ml).
PZA (300 µg/ml) is pending FDA clearance. The total VersaTREK Myco susceptibility
system consists
of specific lots of VersaTREK Myco Broth and VersaTREK Myco GS that are prequalified
to be used with each VersaTREK Myco TB Susceptibility Kit. There are 50 tests per kit.
* Myco PVNA should be used when delays greater than 8 hours are expected
before processing.

Proof in Performance
Performance Characteristics1,2
Isolation of Mycobacteria in VersaTREK/ESP from 3001 specimens was compared to the “Gold
Standard” 460 radiometric broth system in a multi-center study. Of the positive
cultures, 84% were recovered in VersaTREK/ESP and only 74% were recovered in the radiometric
broth system.
