Prediction of persistence of Listeria monocytogenes ST451 in a rabbit processing plant in the Czech Republic
Original language description
The study was focused on characterization of the genetic diversity of L. monocytogenes isolated from packed fresh rabbit meat obtained from one producer via retail outlets. The partial aim was to compare the characteristics of a suspect persistent strain with strains originating in human cases. The occurrence of L. monocytogenes in vacuum packed rabbit meat was monitored during the period of 2013-2016. All strains were characterized by serotyping, multilocus sequence typing (MLST) and macrorestriction analysis. Selected strains, which represented each year, were analysed using the WGS (whole genome sequencing) method. L. monocytogenes was detected in 38% (21/56) of originally packed rabbit meat samples from one food producer during the whole monitored period. All strains showed the identical serotype (1/2a), AscI/ApaI pulsotype (735/2) and sequence type (ST451). The clonal similarity of strains from rabbit meat was also confirmed on the basis of core genome MLST. This fact suggests the occurrence of a suspect persistent strain in the meat processing plant. Results of cgMLST enabled us to unambiguously exclude rabbit meat as a source of listeriosis in humans caused by the indistinguishable AscI/ApaI pulsotype, although the strains of ST451 carried all genes important for the pathogenicity of L. monocytogenes. No specific genes which may be associated with its persistence in food processing environments were detected among the tested strains of ST451.
