NRL Salm study - Results Molecular typing AST1 = resistance to: AMP-GEN-TET-STR-SMX-NAL-CIP AST2 = resistance to: AMP-NAL-CIP (According to Le Hello et al., 2011, J Infect Dis 204: 675 684)
NRL-Salm study- Discussion All CIP-R isolates are assigned to the SGI1-positive S. Kentucky clone ST198-X1 foods orginating from poultry especially turkey meat seem to be important carrier of the clone We also found for the very first time in Germany, one isolate collected from turkey faeces that showed the CIP resistance and belonged to the clone. First description in turkey primary production
NRL-Salm study - Discussion Human side ST198 is present also in Germany human isolate sent to the NRL-Salm for molecular analysis by the Hesse State Health Office (Dillenburg, Germany): - no travel anamnesis within the last four weeks before disease outbreak - it was assumed that the infection had been acquired in Germany We are currently cooperating with the Robert Koch Institute (Wernigerode, Germany) in order to analyse further 25 CIP-R human isolates. This clone might establish also in Germany as a human infection causing pathogen

S. Kentucky CIP-R in French poultry Between October 2012 and January 2013 2 fatenning turkey farms in Morbihan, France Less than 3 miles away from each other Anses set an alert on january, 22nd, 2013
Local investigation Coordinated by the French Food Directorate, Jan 28-30 Investigated farmers, producer group, mayors, vets To determine the origin of this contamination To evaluate risk of diffusion to the french avian production
Results of the investigation Farm 1 : S. Kentucky CIP-R detected first on oct 2012 Aug 15-22 : farmers on holidays in Morocco Aug 23 : farmers are sick, acute enteritis Aug 24 : 16000 day-old turkeys introduced in the farm Aug 31 : 1350 dead turkeys -> treated with Enrofloxacin during week 1 & 3 Farm 2 : S. Kentucky CIP-R detected first on nov 2012 No providers in common, no material in common Both farm participate to the same «mutual aid» with 3 other poultry breeders from the area The «mutual aid» group was in farm 1 on Nov, 12th and farm 2 on Nov, 13th
Controle mesures Cleaning and desinfection, environment sampled before new batch in both farms Enhanced screening in the area for gallus gallus and turkey farms Anses Salmonella Network mobilize the partner labs to enhance their vigilance (sampling the farmers to see if they are still shading the S. Kentucky CIP R) To date, no new cases identified Follow up next year! For further details contact : sophie.granier@anses.fr
