Norepinephrine-dependently released Dr fimbriae of diffusely adhering Escherichia coli strain IH11128 promotes a mitogen-activated protein kinase ERK1/2-dependent production of pro-inflammatory cytokine, IL-8 in human intestinal Caco-2/TC7 cells.

The diffusely adhering Escherichia coli (Afa/Dr DAEC) are associated with recurrent urinary tract infections in adults as well as with diarrheal disease in infants. We previously demonstrated that in wild-type strain IH11128, the Dr fimbriae is released in the extracellular medium in response to multiple environmental signals such as temperature, low aeration and rich medium. A number of molecules of eukaryotic origin, such as catecholamines, have been reported to stimulate bacterial growth and virulence factor production.

Microbacterium binotii sp. nov., isolated from human blood.

Two strains of non-spore-forming, rod-shaped, Gram-positive bacteria, CIP 101303(T) and CIP 102116, were isolated from human blood in 1976 and 1977, respectively. These strains had chemotaxonomic markers that were consistent with classification in the genus Microbacterium, i.e.

Environmental signals implicated in Dr fimbriae release by pathogenic Escherichia coli.

Afa/Dr diffusely adhering Escherichia coli have been shown to cause urinary tract infections and enteric infections. Virulence of Dr-positive IH11128 bacteria is associated with the presence of Dr fimbriae. In this report, we show for the first time that the Dr fimbriae are released in the extracellular medium in response to multiple environmental signals.

Accumulation of poly(3-hydroxybutyrate) from octanoate in different pseudomonas belonging to the rRNA homology group I.

It is admitted that one of the characteristics of pseudomonads is their inability to accumulate poly(3-hydroxybutyrate). In this paper, we show that poly(3-hydroxyoctanoate) synthesis is restricted to Pseudomonas rRNA homology group I, which includes both fluorescent and nonfluorescent species. However, within the genus Pseudomonas, the P.
