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.

Adenovirus – What do we know and what is new?

Recently, the World Health Organisation (WHO) released a report on acute hepatitis in children with an unknown origin. Even though Adenovirus is a hypothesis as being one of the strongly associated reasons for Hepatitis in this report, it is still under investigation. United Kingdom is one of the highly affected countries. PCR analysis has been the first line of diagnosis. Blood sampling, respiratory sampling and stool sampling are being used to collect specimen. Respiratory specimen in a VTM such as the ∑-Virocult® (Viral transport media) and ∑-MM™ inactivation media can be used to collect samples.

Polio – what can we do to prevent it?

Poliovirus can be cultured from faeces which usually goes through a prolonged cell culture process. MWE’s Faecal Transwab® compatible with PCR, would be a suitable medium to collect and transport the sample to the laboratory if faecal sample was not readily available or desirable.
