Characterisation methods Conventional multiplex PCR (sea to see and ser and seg to sej and sep) Multiplex RT-PCR (soon) PFGE: EURL method (2010) Training courses Conventional multiplex PCR: - next course: 19-20 November 2015, invitation - registration - last course: 2014 PFGE: - last course: 5-7 November 2013 (4 participants) Analytical development Validation of a multiplex real-time (RTi) PCR method for se genes detection For the investigation of staphylococcal food-borne outbreaks (SFPOs), it is often necessary to detect the presence of se genes in CPS strains, in addition to SE detection in the suspected food, in order to confirm the identity of the food responsible for SFPO. EURL CPS has been developing a multiplex real-time (RTi) PCR scheme for the detection of 13 se genes. A validation trial is on going, results are expected for the 15 December 2015. The method expected to be dispatch in 2016. Molecular alternative methods to PFGE  1. spa-typing Internal method available - please contact the EURL for further details 2. MLVA This was a Multi Locus Variable number tandem repeat (VNTR) Analysis (MLVA), coupled with capillary electrophoresis (CE). 16 VNTR loci have been selected, including those described by Pourcel et al (Journal of Clinical Microbiology, 2009, 3121-3128). This protocol was tested on a large panel of strains including reference and field food strains. The results obtained showed that MLVA was as discriminatory as PFGE. 3. NGS Method to be assessed compared to PCR, PFGE, MLVA and spa-typing. Work for 2016-2017: bibliographic study and comparison with a batch of well characterised strains. Technical assistance to NRLs EURL CPS will ensure scientific and technical assistance for the characterization of CPS strains (detection of se genes and typing of CPS strains) for NRLs upon request. - Analysis at the charge of the EURL; - Transport of samples at the charge of the NRL Samples should be sent to Yacine NIA (ACI-MON-017) - Anses - 22, rue Pierre et Marie Curie 94701 Maisons-Alfort cedex Dispatch of strains Upon request of the NRLs and in order to implement methods for detection of se genes and for sub-typing of CPS strains, EURL CPS would send CPS field strains and/or DNA material from its collection to the NRLs.
