Phylogeny and functional conservation of sigma (super)E in endospore-forming bacteria
Article Abstract:
Research has been conducted on the sporulation processes between Bacillus spp. and Clostridium spp. Results indicate the presence of the common phylogenetic ancestor for sigma (super)E in these bacteria.

Comparative genetic characterization of Listeria monocytogenes isolates from human and animal listeriosis cases
Article Abstract:
Listeria monocytogenes isolates from animal and human listeriosis cases have been subjected to comparative genetic characterization using automated ribotyping and PCR-restriction fragment length polymorphism (RFLP) typing of the virulence genes hly and actA. Results may show host specificities or unique pathogenic potentials. Ribotyping, especially with PCR-RFLP of hyl and actA virulence genes, is an effective way to differentiate/characterize L. monocytogenes isolates.

Listeria monocytogenes isolates from foods and humans form distinct but overlapping populations
Article Abstract:
Studies done on molecular subtyping of 502 food isolates and 492 human isolates of Listeria monocytogenes by using automated EcoRI ribotyping and PCR-restriction fragment length polymorphism analysis of the virulence gene hly (17,42) are described. Results demonstrate that the L.monocytogenes population associated with the raw and ready-to-eat (RTE) foods tested varied significantly from the population associated with human clinical cases, both in subtype composition and in the ability to infect mammalian cells in tissue culture thus supporting the presence of virulence and transmissibility differences among L.monocytogenes subtypes.
