Sigma TSB with 6.5% NaCl

Product catalog summary

Product Overview: Sigma TSB^TM with 6.5% NaCl is a swab-based device designed for the direct collection and rapid processing of MRSA screening specimens. It includes a vial of tryptic soy broth enriched with 6.5% sodium chloride and a swab that can be snapped into the vial for incubation and subsequent inoculation onto chromogenic agar for MRSA detection.

Specifications: The product contains 2ml of tryptic soy broth with 6.5% sodium chloride, promoting the growth of MRSA and MSSA while inhibiting other bacteria like E. coli. It is compatible with automated processing platforms and includes either a standard or rectal swab with a cellular polyurethane foam bud.

Procedures: Specimens can be collected from various sites such as the nose, throat, axilla, perineum, groin, or rectum. After collection, the swab is snapped into the vial, which can be incubated immediately or transported to a laboratory. Optimal results are achieved after overnight incubation at 37°C, but acceptable results can be obtained after a few hours.

Performance and Recommendations: Studies indicate that broth enrichment significantly enhances the sensitivity of chromogenic media for MRSA detection. Preincubation in broth with 6.5% sodium chloride is recommended and widely adopted in laboratories.

Order Information: The product is available in two variants: MWTSB65 with a standard swab and MWTSB65R with a rectal swab, each packaged in sets of 125.

References: The document cites studies and guidelines that support the use of broth enrichment for improved MRSA detection, including works by Kluytmans-van den Bergh et al. (2014) and McAllister et al. (2011).

Excellent up-take and release of specimen Direct enrichment for MRSA screening specimens. For automated platforms or manual processing. Sigma TSBTM is a swab based device for the direct collection and rapid processing of MRSA screening specimens. The swab is used to collect specimen in normal way from nose, throat, axilla, perineum, groin or rectum in accordance with local procedures. The swab is then snapped into the vial. When the cap is replaced, the swab is automatically “captured” by the cap. The product includes a vial of TSB enrichment broth and a swab which can be snapped into the vial....
