Sigma Virocult meets CLSI-M40-A2

CLSI’s ‘Quality Control of Microbiological Transport Systems’ provides a method to determine collection devices suitable for the transport of viral specimens over extended distances

A clinical study was carried out Andrew Rusdale, Health Protection Agency, to evaluate ∑–VIROCULT® in accordance to CLSI-M40-A.

In the present study the panel of viruses which were evaluated using Sigma Virocult® were Adenovirus 1, Influenza A, Parainfluenza 3, Rhinovirus, and Herpes Simplex Types 1 and 2.  Survival was studied after holding times of up to 7 days, and at holding temperatures of 4°C (refrigeration) and 22°C (representing ambient temperatures).

∑–VIROCULT® was shown to successfully recover all 6 viruses after holding for up to 7 days, and whether held at 4°C or ambient temperature.

The ∑–VIROCULT® swab has been around for many years, and there have been many studies in the past showing it to be effective for most of the common respiratory and skin associated viruses. The present study has provided the opportunity to assess the ∑–VIROCULT® swab in a new era, using current materials and cell lines.

SIGMA VCM meet and exceed CLSI M40-A2 requirements

A study done by Cardiff University showed that Ʃ-VCM transport medium met and exceeded the basic requirements for transport of bacteria set
out by the Clinical and Laboratory Standards Institute Standard M40-A2. Viability of Ureaplasma species in Ʃ-VCM transport medium was stable for 4 days at room temperature. Viability could be extended to at least 264 hours if kept at 4˚C.
