E. coli strains

General

SSI Diagnostica has a strain collection containing more than 64,000 E. coli strains, of which most are clinical isolates. The collection contains both wild types and reference strains.

Product description

The reference strains are primarily sold as freeze-dried ampoules, whilst most wild type strains are sold as agar slant in transport medium. Freeze-dried strains can be stored for many years in unopened ampoules at room temperature. Once the ampoule is opened, the strain must be used immediately. Strains sent in agar slant must be plated out within a week from receipt and resown, as strains cannot survive in transport agar for long. All strains are typed for the antigen they are sold under just before sale.

Use

The strains sent in agar slant can be plated out directly, while the freeze-dried ampoules must be added 1 mL bouillon, incubated overnight at 37°C, and the entire ampoule contents must be transferred onto a plate. The plate is incubated overnight at 37°C, and the strain can now be used for the intended purpose, or frozen slants can be made of it.

If you have E. coli strains that cannot be typed, please contact SSI Diagnostica, info@ssidiagnostica.com.

Product range

When purchasing bacterial strains, we kindly ask you to fill out a Material Transfer agreement.

We primarily sell reference strains and have reference strains for all O, H, K and F antigens, various toxins and other E. coli virulence factors.
The strain collection also contains wild type strains representing a wide selection of the possible serotypes and virulence factors in various combinations. When ordering a wild type strain, it is important to specify which antigen/virulence combinations are required, as our strain bank, as mentioned, consists of more than 64,000 strains. For example, an order may appear as follows:

A) An O149:H18 strain. The rest of the antigens and virulence factors are unimportant.

or

B) Three strains that all contain the eae gene. Serotype irrelevant. 

or

C) Six O26 strains with different H antigens. 

Please note, concerning the OK O serotypes, that except for the OK O strains OK O26, OK O45, OK O55, OK O114 and OK O157, the other OK O serotypes are matched with the O strains with the corresponding number e.g. OK O86 antisera is matched with the O86 strain.

Note, that due to the nature of some of the E. coli strains (marked with "*") they will be added an extra shipment cost. These are send according to UN 2814.

Strains which are not marked "*" are send according to UN 3373.
