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.

Influence of Temperature on the Physiology and Virulence of the Insect Pathogen Serratia sp. Strain SCBI [PDF]

, 2012
The physiology of a newly recognized Serratia species, termed South African Caenorhabditis briggsae Isolate (SCBI), which is both a nematode mutualist and an insect pathogen, was investigated and compared to that of Serratia marcescens Db11, a broad-host-

Hemolytic activity ofMonocercomonasspp. [PDF]

Parasite, 1998
The hemolytic activity of an isolate of Monocercomonas spp. from Tropidophis melanurus (snake: Boidae) was investigated. The isolate was tested against human erythrocytes of groups A, B, AB and O and against erythrocytes of six adult animals of different species (rabbit, rat, chicken, horse, bovine, and sheep).

Carboxyl-Terminal Residues N478 and V479 Required for the Cytolytic Activity of Listeriolysin O Play a Critical Role in Listeria monocytogenes Pathogenicity

Frontiers in Immunology, 2017
Listeria monocytogenes is a facultative intracellular pathogen that secretes the cytolysin listeriolysin O (LLO), which enables the bacteria to cross the phagosomal membrane. L.

Discovery of two skin-derived dermaseptins and design of a TAT-fusion analogue with broad-spectrum antimicrobial activity and low cytotoxicity on healthy cells [PDF]

PeerJ, 2018
Two novel peptides belonging to the dermaseptin family, namely DRS-CA-1 and DRS-DU-1, were encoded from cDNA libraries derived from the skin secretions of Phyllomedusa camba and Callimedusa (Phyllomedusa) duellmani.

Increased Risk of Thrombocytopenia and Death in Patients with Bacteremia Caused by High Alpha Toxin-Producing Methicillin-Resistant Staphylococcus aureus

Toxins, 2021
Alpha toxin (Hla) is a major virulence factor of Staphylococcus aureus that targets platelets but clinical data on Hla pathogenesis in bacteremia (SAB) is limited. We examined the link between in vitro Hla activity and outcome.

The hemolytic and cytolytic activities of Serratia marcescens phospholipase A (PhlA) depend on lysophospholipid production by PhlA

BMC Microbiology, 2009
Background Serratia marcescens is a gram-negative bacterium and often causes nosocomial infections. There have been few studies of the virulence factors of this bacterium. The only S.

New amphiphilic amino acid derivatives for efficient DNA transfection in vitro [PDF]

, 2017
Nucleic acids-based therapies have recently developed as next-generationagents for treating and preventing viral infection, cancer, and genetic disorders,but their use is still limited due to its relatively poor delivery into targetedcells.

Characteristics of hemolytic activity induced by skin secretions of the frog Kaloula pulchra hainana

Journal of Venomous Animals and Toxins including Tropical Diseases, 2013
Background The hemolytic activity of skin secretions obtained by stimulating the frog Kaloula pulchra hainana with diethyl ether was tested using human, cattle, rabbit, and chicken erythrocytes.
