Bacterial and Viral Culture collections


Many of these isolates already have established sensitivity profiles, so we can selectively test organisms of known characteristics.

Virus Collection


We have a large collection of characterised virus suitable for the veterinary scientific community. This vital archive of pathogens helps researchers understand disease and ultimately protect animal health.

Availability of specific strains can not always be guaranteed. Our listed items serve as an example of what we can offer rather than an exhaustive catalogue. Turnaround times may vary depending on the complexity of the request and current demand. If you have any specific questions or requirements, please feel free to contact us for more information. 

For reference, please see our standard terms and conditions and contract for supply of goods or services.

Bacterial collection

We have collected over 15,000 isolates including:

  • Over 500 Pasteurella multocida strains.
  • Over 4,500 E.coli strains.
  • Over 1,000 Salmonella species.
  • More than 1500 common mastitis pathogens.

These include:

  • Brachyspira.
  • Clostridia.
  • Fusobacteria.
  • Bacteriodes species.

We can provide you with collections of recent isolates to meet your requirements and can collect isolates if you have a specific need not covered by the current collection.

We also offer an anti-microbial susceptibility service using several minimum inhibitory concentration (MIC) assays, performed under ISO 17025.

Up-to-date profiles for a wide range of currently marketed or research antimicrobials are available and are suitable for product registrations or marketing. For more information please visit our antimicrobial resistance testing page.
