  • Title: [Pseudomonas fluorescens: production of pyoverdine in human blood at 4 degrees C and cytotoxic effect of the pigment].
    Author: Pájaro MC, Barberis IL, Albesa I.
    Journal: Rev Latinoam Microbiol; 1995; 37(1):1-6. PubMed ID: 7784726.
    Abstract:
    Pseudomonas fluorescens PAB strain produced pyoverdine in a synthetic medium, this pigment was purified by solvent extraction and ion exchange, then sterilized by filtration. Where cytotoxic effect on human leukocytes was assayed, death and lysis was observed. Sublytic doses decreased leukocytes phagocytosis and chemotaxis. Bacteria grew and produced pigment in blood stored a 4 degrees C, with a pyoverdine production of 0.13 mg/ml of serum after 5 days of incubation.
