Diversity of microbial communities colonizing the walls of a Karstic cave in Slovenia.

On the basis of analysis of genes for 16S rRNA, Bacteria from eight phyla were determined in biofilm microbial communities from a Karstic cave in Slovenia.

Genes regulated by the Escherichia coli SOS repressor LexA exhibit heterogenous expression.

Expression of the E. coli SOS genes recA, lexA and cka was investigated on the basis of fluorescence of gene fusions with the gfp gene encoding the green fluorescent protein. Single cell analysis employing fluorescent microscopy revealed heterogenous expression of SOS genes among populations of genetically identical bacterial cells.

Prevalence and associations of the tcpC gene among Escherichia coli urinary tract infection, skin and soft tissue infection, and commensal isolates.

We investigated the prevalence of gene tcpC encoding a protein with a Toll/interlevkin-1 receptor domain involved in suppression of innate immunity among a collection of pathogenic E. coli strains and 90 E. coli commensal strains. Statistical analysis of our results revealed that the tcpP gene is more prevalent among pathogenic than among commensal strains and it is associated with the phylogenetic group B2 as well as genes for virulence factors cnf1, hlyA, papGIII, sfaDE and usp

Human perforin permeabilizing activity, but not binding to lipid membranes, is affected by pH

Surface plasmon resonance revealed that pore formation by human perforin is affected by calcium but not by pH. The conformation of perforin was assessed by monoclonal antibodies.

Dynamics of microbial and viral communities in four aquatic environments

Investigation of the temporal dynamics of clonal lineages of Haloquadratum walsbyi in slaterns, revealed that the taxomic composition and metabolic capabilities of clonal lineages of H. walsbyi and their predators are relatively constant.
