Isolate Collection

The BSAC Resistance Surveillance Project has built up an unrivalled collection of bacterial isolates from bloodstream infections and lower respiratory tract infections. Together with the extensive information on their resistance profiles, this forms a unique resource for further research.

The BSAC surveillance collection is generally more useful than ad hoc collections because the isolates were collected according to a defined surveillance protocol and from a large number of clinical centres. Unlike a single-centre or special-interest collection, it can be seen as broadly representative of respiratory and bloodstream pathogens in the UK and Ireland over the study period. The skewing impact of outbreaks is limited by the multi-centre design, and the simple inclusion of consecutive non-duplicate isolates guards against selection bias and over-representation of ‘interesting’ or highly resistant strains.

Isolates included are:

Community-onset lower respiratory infections from October 1999 S. pneumoniae, H. influenzae, M. catarrhalis
Hospital-onset lower respiratory infections from October 2008 S. aureus, Pseudomonas, Acinetobacter, Enterobacteriaceae
Bacteraemia: majorGram-positive groups from January 2001 S. aureus, coagulase-negative staphylococci, enterococci, S. pneumoniae, other alpha- and non-haemolytic streptococci, beta-haemolytic streptococci
Bacteraemia: majorGram-negative groups from January 2001 E. coli, Klebsiella, Enterobacter, Proteeae, Serratia, Pseudomonas.
Bacteraemia: minor groups 2001 – 2007 [small numbers of assorted other Gram-negatives]
