Toxins of Pseudomonas aeruginosa: new perspectives
WebExotoxin A is an extracellular enzyme that is produced by most clinical strains of Pseudomonas aeruginosa. It is a single-chain polypeptide (molecular weight, 71,000) with A and B fragments that mediate enzymatic and cell-binding functions, respectively. WebA 1:100 dilution produced cytotoxicity of 16.3% towards A549 cells. A similar result was obtained when the culture supernatant fluids were collected when the culture was grown aerobically to a cell number of 7.2×10 8 CFU/ml (cytotoxicity 13.5%). gartner what is ai
