population structurewithin 252 L. gelidum subsp. gasicomitatum strains was determined based on a novel MLST scheme employing seven housekeeping genes. These strains had been isolated from meat and vegetable sources over a time span of 15 years and the findings seem to indicate that certain strains are growing inmeat better than in vegetables or contamination sources associated with meat or vegetable processing are different. Since L. gelidum subsp. gasicomitatum has not been associated with animal carcasses during early stages of slaughtering it is most likely that factors
associated with the capability to grow in different foods explain the niche specificity observed. Lastly, the large diversity of biotypes of this subspecies was further documented and the strain-specific ability to adhere on stainless steel and glass food contact surfaceswas recently demonstrated
