Description:This photograph depicts the colonial morphology displayed by Gram-negative Pseudomonas fluorescens bacteria, which was grown on a medium of sheep’s blood agar (SBA), for a 24 hour time period, at a temperature of 37°C. See PHIL 12458, for a closer view of these bacterial colonies.
Normally, Pseudomonas fluorescens is thought of as being nonpathogenic to humans. Those who have been infected, usually displayed a compromised immune system, such as would be found in a chemotherapy, or acquired immune deficiency syndrome (AIDS) patient, which would define P. fluorescens as more of an opportunistic organism. However, of interest, is the ability of this organism to produce Mupirocin, an antibiotic that has proven to be effective in the treatment of ear, eye, and skin infections.
