NCTC supplies reference bacterial cultures, including many type strains, of medical, scientific and veterinary importance worldwide. NCTC strains support academic, health, food and veterinary institutions and are used in microbiology laboratories in a range of different sectors and in research institutes worldwide. Founded in 1920, NCTC is the longest-established collection of its type anywhere in the world, and also serves as a United Nations Educational, Scientific and Cultural Organization (UNESCO) Microbial Resource Centre (MIRCEN).
The collection (which is certified to BS EN ISO 9001:2008) comprises over 5,000 bacterial cultures, all of which are available in a freeze-dried (lyophilised) format. A selection of strains are also available in a simple single-use LENTICULE disc format.
NCTC provides a range of associated services which include an International Depository Authority (IDA) patent depository for bacterial cultures.
NCTC is one of four culture collections that constitute the Culture Collections of Public Health England and has access to the wide-ranging expertise of an internationally-renowned body of specialists in clinical, food, water and environmental microbiology, genomics and proteomics, from across the wider PHE organisation.
NCTC consists of nearly 5100 type and reference bacterial strains. The strains represent many different species from specific disease conditions and widespread geographical locations; many have known antimicrobial resistance mechanisms/patterns; some contain specific plasmids. The collection is of fundamental importance to the biomedical scientific community and many of the strains are stipulated in internationally recognised standard methods as definitive control strains for various microbiological testing procedures. The strains are preserved as characterised, authenticated freeze-dried (lyophilised) cultures in fused-glass ampoules, which are stored mainly at 10°C, although some are stored at -30°C. Cultures are supplied as freeze-dried (lyophilised) ampoules.
In addition, 150 strains are also avaiable as Bacterial DNA. The DNA supplied (approximately 2µg) is high molecular weight and is therefore suitable for a wide range of molecular applications including whole genome sequencing.
