Antimicrobial resistance testing

Our tests are performed under ISO 17025. This ensures your data is of the highest standard of quality, impartiality and credibility for your customers and regulatory authorities.

Testing services

APHA has centres of expertise dedicated to antimicrobial testing and anaerobic work. Our techniques are continuously updated to ensure they are in keeping with advances in the human field as well as veterinary specialisation.

We routinely offer several minimum inhibition concentration (MIC) assays:

Agar plate and broth dilution MICs

Disc diffusion sensitivity by zone size

Sensititre MIC

All these conform to British Society for Antimicrobial Chemotherapy (BSAC) or Clinical and Laboratory Standards Institute (CLSI) standards.

We can provide quotes for other methodologies according to your requirements.

Bacterial isolates

To support these services, We maintain over 29,000 recent and historic bacterial isolates of large animal pathogens. This extensive collection includes both common and less common anaerobes from all livestock species.

For more information on our culture collection service, please see our pages on culture collection.
