Cell-associated hemolysis activity in the clinical strain of Pseudomonas fluorescens MFN1032

BMC Microbiology, 2010
Background MFN1032 is a clinical Pseudomonas fluorescens strain able to grow at 37°C. MFN1032 cells induce necrosis and apoptosis in rat glial cells at this temperature. This strain displays secretion-mediated hemolytic activity involving phospholipase C

Mechanism of Low Hemolytic Activity of Alkyl Type Nonphosphorous Cationic Glycerolipids: Study on Model Membranes

Клиническая онкогематология, 2014
Nonphosphorous alkyl cationic glycerolipids cause death of tumor cells with minimal damage of erythrocytes. In this article we demonstrate, that low hemolytic activity of these compounds can be explained by their weak ability to damage the integrity of ...

Hemolytic Activity of Aminoethyl-dodecanoates

Zeitschrift für Naturforschung C, 1998
Abstract The effect of new lysosomotropic compounds on red blood cell hemolysis and erythrocyte membrane fluidity has been investigated. In earlier studies it was shown that the compounds inhibit the growth of yeast and plasma membrane H+-ATPase activity.

Nutrient Alteration Drives the Impacts of Seawater Acidification on the Bloom-Forming Dinoflagellate Karenia mikimotoi

Frontiers in Plant Science, 2021
Seawater acidification and nutrient alteration are two dominant environmental factors in coastal environments that influence the dynamics and succession of marine microalgae. However, the impacts of their combination have seldom been recorded.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
