Streptococcus Strains

SSI Diagnostica sells a small selection of the most prevalent streptococcal strains.

Product description

The strains are sold and delivered primarily as freeze-dried ampoules. Unopened vials can be kept for a long time at room temperature.

If we do not have a freeze-dried ampoule, it may instead be delivered in transport medium, if desired.

All strains are grouped and typed before sale.

The strains are for in vitro use as control strains for serotyping and may not be used for commercial purposes (e.g. sales, manufacturing of vaccines, antibodies, etc.) without prior written agreement with SSI Diagnostica.

SSI Diagnostica sells some of the most prevalent streptococcal strains.

All strains are grouped and typed before sale.

How to use

Strains should be stored at 5°C and must be spread on a 5-10% blood agar plate within one week, as the culture cannot survive in the transport medium for longer.
All strains are supplied with a certificate in which group and serotype and lot number are listed. We recommend that the strains are grown at 36-37° C overnight, in air containing 5% CO2, on agar with 5% blood or broth with 1% serum.
