Genomic analysis of Listeria monocytogenes diversity over a 10-year period in Uruguay.

ABSTRACT: Listeria monocytogenes is a globally relevant foodborne pathogen and a major public health concern because of its ability to cause severe invasive disease and persist in food processing environments. This study aimed to characterize the genomic diversity of L. monocytogenes isolates collected in Uruguay from food and clinical cases of listeriosis between 2010 and 2019. The genomes sequences of 142 isolates representatives from a national collection were obtained and used for comparative genomic and phylogenetic analysis along with other 55 genomes from different geographical regions. The isolates belonged to lineages I (88%) and II (12%) and were distributed across 20 clonal complexes. The clonal complexes CC3, CC2, and CC1 were predominant. Notably, CC3 accounted for nearly one-third of t
