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.

Differential expression of hemolysin genes in weakly and strongly hemolytic Brachyspira hyodysenteriae strains

BMC Veterinary Research, 2020
Background Swine dysentery (SD) is a diarrheal disease in fattening pigs that is caused by the strongly hemolytic species Brachyspira (B.) hyodysenteriae, B. hampsonii and B. suanatina. As weakly hemolytic Brachyspira spp. are considered less virulent or

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 ...

Bothrops snake venoms and their isolated toxins, an L-amino acid oxidase and a serine protease, modulate human complement system pathways

Journal of Venomous Animals and Toxins including Tropical Diseases, 2015
Background Activation of the complement system plays an important role in the regulation of immune and inflammatory reactions, and contributes to inflammatory responses triggered by envenomation provoked byBothrops snakes.

Inhibitory Effect of Andrographis paniculata Lactone on Staphylococcus aureus α-Hemolysin

Frontiers in Pharmacology, 2022
We investigated the effect of andrographolide (AP) on the hemolytic capacity of Staphylococcus aureus (S. aureus) isolated from our region. AP is a labdane diterpenoid isolated from the stem and leaves of Andrographis paniculata. The hla gene from 234 S.
