If you use data from this site you must acknowledge the BSAC, but you cannot claim BSAC authority for any analyses you make yourself. More detail.

Further Research
We can supply isolates from the project for further study in recognised laboratories. We can also collaborate on more detailed analyses or presentations of the data, and links with other datasets. Please contact us for details.

WHICH BREAKPOINTS?

WHICH BREAKPOINTS?

The breakpoints used to classify isolates as susceptible/intemediate/resistant on this website are the version 9 BSAC breakpoints (January 2010), with a correction for Pseudomonas-tzp (S<=16). In a few cases, where BSAC breakpoints have not been set, EUCAST v 1.0 breakpoints are used (for S. pneumoniae with cli, dor, min and tec; alpha-haemolytic streptococci with dor, etp, ipm and mem; beta-haemolytic streptococci with dor, ipm, mem, min, tec and van; H. influenzae with min; and M. catarrhalis with amx, ctx and min).

More recent breakpoints may exist.

BREAKPOINT HISTORY

From 10th March 2010, version 9 BSAC breakpoints (Jan 2010).

From 1st July 2009 to 10th March 2010, version 8 BSAC breakpoints (Jan 2009).

From 26th September 2008 to 1st July 2009, version 7.1 BSAC breakpoints (Feb 2008).

From 6th Feb 2007 to 26th Sept 2008, version 6.1 BSAC breakpoints (Feb 2007).

From 14th March 2006 to 6th Feb 2007, version 5 BSAC breakpoints (Jan 2006).

From January 2006 to 14th March 2006, version 4 BSAC breakpoints (Jan 2005).

At each time, some EUCAST breakpoints were used for a few combinations where BSAC breakpoints had not been set.		 
DEFINITIVE BREAKPOINTS
2010-03-12

DEFINITIVE BREAKPOINTS

This site lists breakpoints only for antibiotic/organism combinations tested in the BSAC Resistance Surveillance Project; they were extracted from BSAC and EUCAST sources in March 2010. Recommendations may have changed since then. Please visit the BSAC or EUCAST websites for the most recent complete annotated tables.		 
CHANGING BREAKPOINTS

CHANGING BREAKPOINTS

We aim to use current breakpoints on this website. As a result, the percentages of isolates shown as susceptible/intermediate/resistant may differ from those published in previous papers or calculated on the website at an earlier date with earlier breakpoints.
