英文: There are two types of hemolysis on blood agar plates: alpha, beta, and gamma (gamma hemolysis is actually no hemolysis).中文: 血平皿上有两种类型的溶血:α、β和γ(γ溶血实际上就是不溶血)。英文: Effects of bovine viral diarrhea viruses in vitro on transcription of interferon-alpha,...

Hemolytic effect on blood agar allows differentiation into those causing partial hemolysis (alpha-hemolysis), complete hemolysis (beta-hemolysis), and no hemolysis (gamma-hemolysis). The beta-hemolytic streptococci are classified by the antigenic characteristics of their cell wall into Lancefiel...
It is possible that an African-American individual may have HbS/HbG where the hemoglobin molecule contains one normal alpha chain, one alpha G chain, one normal beta chain, and one beta S chain. This can result in the detection of various hemoglobins in the blood, including HbA (alpha 2,...
A total of 229 patients infected with SA strains exhibiting varying zone sizes of beta-hemolysis on SBA were included. A total of 539 images of bacterial growth on SBA were generated as inputs for model development. One-third of patients developed thrombocytopenia at onset, with an...
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 ...
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...
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 Hla production based on image interpretation...
2.2. High Correlation of Hla Protein Level and Hemolytic Activity We evaluated Hla expression by first determining the correlation between protein levels and hemolytic activity measured by Western immunoblot and hemolysis assays, respectively, in a subset of 61 clinical isolates, representing survivors and...
