ABSTRACT 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.

ABSTRACT Salmonella enterica subsp. enterica serovar Enteritidis emerged in the late 1980s as the most isolated Salmonella serovar worldwide. Here, we report the draft genomes of 256 S. Enteritidis strains isolated from humans, food, chickens, and farm environments in Brazil. These draft genomes will help enhance our understanding of this serovar in Brazil.

ABSTRACT 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.

Draft Genome Sequences of Histamine-Producing Morganella psychrotolerans Strains

Kristin Bjornsdottir-Butler; Maria Sanchez Leon; Ronald A. Benner

ABSTRACT Histamine-producing bacteria are responsible for scombrotoxin (histamine) fish poisoning, a leading cause of fish poisoning in the United States. We report here the first draft genomes of three histamine-producing Morganella psychrotolerans strains, isolated from tuna and mahi-mahi.

Draft Genome Sequences of Histamine- and Non-Histamine-Producing Photobacterium Strains

Kristin Bjornsdottir-Butler; Maria Sanchez Leon; Paul V. Dunlap; Ronald A. Benner

ABSTRACT Histamine-producing bacteria (HPBs) have recently been identified from the marine environment. The identification and characterization of HPBs is important to developing effective mitigation strategies for scombrotoxin fish poisoning. We report here the draft genomes of seven histamine-producing and two non-histamine-producing marine Photobacterium strains.
