Antimicrobial activity :

Most Psuedomonas species are penicillin resistant, so other choices for treatment might include Ciprofloxacin, ticarcillin, imipenem or piperacillin. This resistance is due to their cell walls which contain prions. [1]

My Results Ceftazidine proved very effective Clove and tea tree oil very effective

Cell Structure, Metabolism and Life Cycle

P. fluorescens is an anerobe and uses sideophores when its iron levels are low. when the sidephores are being activated this is what gives off the fluorescent color. [3]

Physiology and Pathogenesis

Pseudomonas fluorescens may be useful in protecting plants from fungus and nemotade attacks.[2] P. fluorescens can be found in soil, water and plant surfaces. It is well suited to survive in mineral content soil and is being studied for its use for biocontrol in agriculture. Monsanto has detected the natural pesticide abilities and has even spliced P. fluorescens with Ecoli and added another gene to create a constant glow from the modified bugs to help track and prove that these bugs would not spread uncontrollable if used as a pesticide in the fields. [5]

P. fluorescens demonstrates hemolytic activity and, as a result, has been known to infect blood transfusions.[2]

It is also used in milk to make yogurt.[2]

Disease:

P. fluorescens can be found infecteing those who are immunocompromised including cancer patients.[2]

Medical Properties:

Psuedomonas fluorescens has hemolytic properties and can infect blood transfusion. It can also be used as a strater for yogurts. P. fluorescens can be used to make the antibiotic Mupirocin which can be used to treati MRSA, skin, ear, and eye disorders.[2]
