Abstract

In this study, the GB-speckles were used to study the probable precursor for L. monocytogenes ST734 strains, which were detected twice in the world, namely: for the first time in Chile in 2009 and, recently, in 2019 in the Republic of Serbia. We found that these strains belong to the clonal complex I and differ fromL. monocytogenes ST1 strains by a single nucleotide change in the gene dat. This is the first report demonstrating the using GB-speckle-structures to detect evolutionary genetic changes in L. monocytogenes strains.
