Genome Sequences of Three Frequently Used Listeria monocytogenes and Listeria ivanovii Strains

ABSTRACT Listeria monocytogenes is a foodborne pathogen that causes the often-fatal disease listeriosis. We present here the complete genome sequences of six L. monocytogenes isolates of sequence type 9 (ST9) collected from two different meat processing facilities in Norway. The genomes were assembled using Illumina and Nanopore sequencing data.

ABSTRACT Here, we report the complete genome sequences of three Bacillus amyloliquefaciens strains isolated from alfalfa, almond drupes, and grapes that inhibited the growth of Listeria monocytogenes strain 2011L-2857 in vitro. We also report multiple gene clusters encoding secondary metabolites that may be responsible for the growth inhibition of L. monocytogenes.

Listeria Ivanovii

To determine the incidence of Listeria monocytogenes in raw milk, an isolation method was evaluated and used to analyze milk from three areas of the United States. The incidence varied by area from 0% in California to 7% in Massachusetts, with an overall incidence of 4.2%. The highest incidence found in any area during a single sampling period was 12% in Massachusetts in March 1985. During that same sampling, the incidence for all Listeria species was 26%. Of the 27 L. monocytogenes strains isolated during the survey, 25 were pathogenic in adult mice. One of three Listeria ivanovii isolated was pathogenic. No other isolates demonstrated pathogenicity.

Immunocompromised Mice

Thirty food and clinical isolates of Listeria were compared quantitatively in regard to lethality in immunocompromised mice, hemolytic activity for sheep erythrocytes, invasiveness towards Hep-2 epithelial cells, and cytotoxicity to CHO cells. All Listeria monocytogenes isolates were hemolytic, invasive, weakly cytotoxic, and lethal to immunocompromised mice. Listeria ivanovii isolates expressed the first three properties but were non-virulent. There was little quantitative correlation among the virulence markers, suggesting that there may be additional virulence related factors that may influence the pathogenicity of L. monocytogenes isolates. No systematic differences between the clinical and food isolates were apparent. Electron and light microscopy of infected Hep-2 cells revealed L. monocytogenes and L. ivanovii encapsulated within cell processes containing an actin matrix.
