Invitation to NordicAST Bacteroides study

We hereby invite Nordic (Denmark, Finland, Iceland, Norway and Sweden) laboratories to examine a collection of Bacteroides spp. with varying degrees of resistance to meropenem, piperacillin/tazobactam, clindamycin and metronidazole, as well as varying degrees of MBL production, in a multi-centre, blinded format.

The aims of this study are:

1. To examine the performance of the new EUCAST disk diffusion method for susceptibility testing of Bacteroides spp., compared with reference methodology;
2. More specifically, to examine the reliability of disk diffusion and gradient diffusion in carbapenem-nonsusceptible strains, and the suitability of these methods for routine susceptibility testing and carbapenemase screening;
3. To assess the suitability for routine laboratory use of phenotypic tests for MBL production.

More infiormation is available in the documents below.

The deadline for registration is 20 June 2018.

Please contact Tore Taksdal Stubhaug if you have any questions.
