Bacterial and Viral Culture collections

APHA Scientific offers a wide range of bacterial and viral isolates to support your product developments and research. The collection contains a large number of current field strains from a wide geographical area within the UK and many of the isolates are associated with clinical data.

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.
