Regulation of the cytotoxic effects of Pseudomonas fluorescens by growth temperature.

We had previously shown that the psychrotrophic bacterium Pseudomonas fluorescens can act as a pathogen, inducing apoptosis and necrosis in neurons and glial cells. In the present study, we investigated the influence of the growth temperature of P. fluorescens on its infectious potential.

Cytotoxic effects of the lipopolysaccharide from Pseudomonas fluorescens on neurons and glial cells.

Pseudomonas fluorescens is an emerging pathogen closely related to Pseudomonas aeruginosa. In the present study, the effect of the lipopolysaccharide (LPS) from P. fluorescens MF37 was investigated using indicators of apoptosis and necrosis and was compared to the effect of the LPS from P.

Pseudomonas fluorescens lipopolysaccharide inhibits both delayed rectifier and transient A-type K+ channels of cultured rat cerebellar granule neurons.

Pseudomonas fluorescens is a Gram-negative bacillus closely related to the pathogen P. aeruginosa known to provoke infectious disorders in the central nervous system (CNS). The endotoxin lipopolysaccharide (LPS) expressed by the bacteria is the first infectious factor that can interact with the plasma membrane of host cells.
