Listeria grayi - Wikipedia
Listeria grayi is a species of bacteria. It is a Gram-positive, facultatively anaerobic, motile, non-spore-forming bacillus. It is non-hemolytic. The species was first proposed in 1966.
Listeria grayi - an overview | ScienceDirect Topics
The Genus Listeria is composed of Listeria grayi, Listeria innocua, Listeria ivanovii, Listeria welshimeri, Listeria seeligeri and L. monocytogenes. All Listeria species are phenotypically similar although only L. monocytogenes and L. ivanovii are pathogenic (Rocourt & Buchrieser, 2007).
Listeria - Wikipedia
Listeria is a genus of bacteria that acts as an intracellular parasite in mammals. As of 2024, 28 species have been identified. [1] [2] [3] The genus is named in honour of the British pioneer of sterile surgery Joseph Lister. Listeria species are Gram-positive, rod-shaped, and facultatively anaerobic, and do not produce endospores. [4]
What are the recognized species of the genus Listeria? - PMC
Listeria is an important food-borne pathogen that affects the elderly, pregnant women, neonates and immune-compromised persons. In the last decade, there has been an increase in identification of new species from diverse sources, but Listeria monocytogenes remains the main pathogenic species of the genus.
PHYLOGENY OF THE CURRENT GENUS LISTERIA - mBio
L. grayi, which has been proposed to be re-classified as Murraya grayi, is the only Listeria sensu lato species that exhibit motility consistent with the classic Listeria spp. (i.e., motile at 20–25°C and non-motile at 35–37°C) and is positive for D-arylamidase activity.
Listeria: growth, phenotypic differentiation and molecular ...
Apr 1, 2003 · L. murrayi, which was a separate species in the genus Listeria, is now included in the species L. grayi. Based on results of DNA–DNA hybridization, multilocus enzyme analysis, and 16S rRNA sequencing, the six species in the genus Listeria are divided on two lines of descent: (i) L. monocytogenes and its closely related species, L. innocua , L ...
Isolation and engineering of a Listeria grayi bacteriophage
Sep 23, 2021 · We describe the isolation and engineering of a novel L. grayi bacteriophage, LPJP1, isolated from farm silage. With a genome over 200,000 base pairs, LPJP1 is the first and only reported...
Genomic and phenotypic data clearly define a distinct group of six species (Listeria sensu strictu) that share common phenotypic characteristics (e.g., ability to grow at low temper-ature, flagellar motility); this group includes the pathogen Listeria monocytogenes.
