Immune Blocking of Fluorescent Antibody Staining of Streptococcus Group A Compared with Anti-streptolysin O
… discribed and compared with the conventional antistreptolysin 0 antibody (ASOA) test in the detection of Streptococcus pyogenes group A antibodies in sera samples.</p> <p>A slide inhibition test was used to detect the presence of FABA in the following manner; (a) fix group A streptococcal cells to …

Transmembranäre Proteintransportsysteme an kultivierten Säugerzellen: Chimären cer C2-Ribosyltransferase von C. botulinum und Streptolysin O
… binären C2-Toxins, bzw. mit dem porenbildenden Streptolysin O (SLO)). Dazu wurden zunächst Toxinchimären konstruiert, die aus der Adapterdomäne von C2I und den zu untersuchenden Glukosyltransferasen bestanden. Über die Adapterdomäne sollten die Fusionsproteine an die bakterielle …

Characterization Of Streptolysin O As The Translocator For The Cytolysin-Mediated Translocation Process In Streptococcus Pyogenes
Secretion of toxins into host cells is an important component of microbial pathogenesis. In order to gain access to the host cell cytosol, toxins must cross the plasma membrane, traverse the membrane of endocytic vesicles, or cross the membrane of organelles. The process …

Development of nanosponges from erythrocyte ghosts for removal of streptolysin-O and α haemolysin from mammalian blood
Bacteria can cause many different types of infections. Virulence factors e.g. adherence proteins, biofilm formation, endotoxins and exotoxins allow invasion by bacteria and cause infections such as respiratory, urinary, and intestinal and blood stream infections. If left untreated they can lead to …

Intracellular labeling of live cells via transient membrane permeabilization for fluorescence and super resolution microscopy
… of living cells. The technique makes use of Streptolysin O (SLO), a bacterial enzyme that permeabilizes cells to DNA, RNA, proteins. We show that SLO can be used to deliver a variety of fluorescent probes; ranging from organic dyes (<1 kDa in size) to fluorescent immunoglobulin antibody (~150 …

Impedance spectroscopy for cellular and biomolecular analysis
… to the effects of the surfactant Tween 20 and Streptolysin-O, a bacterial pore-forming toxin.<br/>Novel electrode materials that reduce the parasitic effect of electrode polarisation are described and characterised. These are iridium oxide and PPy/PSS (polypyrrole/poly(styrenesulphonate)). …

Comprehensive Investigation into the Molecular Mechanisms Driving the Emergence of emm4 Group A Streptococcus
… the potent toxins NAD-glycohydrolase and streptolysin O (Nga/Slo) and upregulation of the <em>msrAB</em> operon, which encodes proteins involved in defense against extracellular oxidative stress. Our findings are in accord with recent surveillance studies, which found a high ratio of …

Organization of the Streptococcal ExPortal and its Interaction with Cationic Antimicrobial Peptides
… the pathogenically relevant SpeB protease and Streptolysin O: SLO) cytolysin. One of the CAPs investigated also targets the lipid II precursor of extracellular peptidoglycan, suggesting the influence of CAPs on ExPortal organization extended beyond their affinity for negatively charged membrane …
