hemolysis testing on blood agar plates of bacterial culture supernatants of the clinical isolates. In addition, nothing was known about the concentrations of Hla actually reached in the body fluids of the infected hosts. Western blot analyses on 36 samples of deep tracheal aspirates (DTA) isolated...
blood cell lysis (hemolytic activity), but assay complexity limits its feasibility for use in the clinical setting. Notably, Hla-producing SA strains exhibit beta-hemolysis when grown on sheep blood agar, and different beta-hemolytic zone sizes may provide a measurable qualitative readout of SA ...
Biological activity of every batch of recombinant Hla was checked using a β-hemolysis assay on blood agar plates (Columbia agar with 5% sheep blood; Becton Dickinson, Heidelberg, Germany). The concentrations of rHla routinely used were 1000 or 2000 ng/mL (30 or 60 nmol/L) for reasons ...
which exhibits phospholipase C and sphingomyelinase activity and damages cell membranes to cause hemolysis and necrosis, increasing the vascular permeability, and triggering platelet aggregation [4,8,9,26,27,28]. At present, there is no specific antibody drug forC. perfringens. Based on the bin...
