Polymorphism of Listeria monocytogenes and Listeria innocua strains isolated from short-ripened cheeses.
Thirty isolates of Listeria monocytogenes and 18 of L. innocua obtained from different short-ripened cheeses manufactured in Asturias (northern Spain), were compared with each other and with reference strains using serotype, phage type and pulsed-field restriction endonuclease digestion profiles analysis of the total DNA. Restriction enzymes ApaI and SmaI defined five clusters in L. monocytogen...
متن کاملThe presence of the internalin gene in natural atypically hemolytic Listeria innocua strains suggests descent from L. monocytogenes.
The atypical hemolytic Listeria innocua strains PRL/NW 15B95 and J1-023 were previously shown to contain gene clusters analogous to the pathogenicity island (LIPI-1) present in the related foodborne gram-positive facultative intracellular pathogen Listeria monocytogenes, which causes listeriosis. LIPI-1 includes the hemolysin gene, thus explaining the hemolytic activity of the atypical L. innoc...
متن کاملPhenotypic and Genotypic Characterization of Atypical Listeria monocytogenes and Listeria innocua Isolated from Swine Slaughterhouses and Meat Markets
In the last decade, atypical Listeria monocytogenes and L. innocua strains have been detected in food and the environment. Because of mutations in the major virulence genes, these strains have different virulence intensities in eukaryotic cells. In this study, we performed phenotypic and genotypic characterization of atypical L. monocytogenes and L. innocua isolates obtained from swine slaughte...
متن کاملAerosol studies with Listeria innocua and Listeria monocytogenes.
Aerosol studies of Listeria monocytogenes in food processing plants have been limited by lack of a suitable surrogate microorganism. The objective of this study was to investigate the potential of using green fluorescent protein-labeled strains of Listeria innocua as a surrogate for L. monocytogenes for aerosol studies. These studies were conducted in a laboratory bioaerosol chamber and a pilot...
متن کامل1,2-β-Oligoglucan Phosphorylase from Listeria innocua
We characterized recombinant Lin1839 protein (Lin1839r) belonging to glycoside hydrolase family 94 from Listeria innocua. Lin1839r catalyzed the synthesis of a series of 1,2-β-oligoglucans (Sopn: n denotes degree of polymerization) using sophorose (Sop2) as the acceptor and α-D-glucose 1-phosphate (Glc1P) as the donor. Lin1839r recognized glucose as a very weak acceptor substrate to form polyme...
