Listeriosis outbreaks are frequently multistate/multicountry outbreaks, underlining the importance of molecular typing data for several diverse and well-characterized isolates. Large-scale whole-genome sequencing studies on Listeria monocytogenes isolates from non-U.S. locations have been limited. Herein, we describe the draft genome sequences of 510 L. monocytogenes isolates from northern Italy from different sources.

Salmonella enterica serotype Enteritidis is a foodborne pathogen of global concern, because it is frequently isolated from foods and patients. Draft genome sequences are reported here for 64 S  Enteritidis strains isolated from the intestines and spleens of mice caught live on chicken farms in the U.S. Northeast. The availability of these genomes provides baseline information on the genomic diversity of S  Enteritidis during the 1990s, when foodborne outbreaks traced to internal contamination of eggs were prevalent.
