Bacteriophages
NCTC have a collection of over 90 bacteriophages which were deposited between 1950 and 1992 primarily for their value in bacterial typing.
Recently, these viruses have been characterised and re-authenticated with a view to making them more accessible to scientists worldwide. The collection consists of Staphylococcus, Streptococcus and Campylobacter bacteriophages.
