Pseudomnas Aeruginosa

By: Megan Allen

What is it?

pseudomonas is a Gram-negative, rod-shaped bacterium in the Gamma Proteobacteria class. The metabolism is respiratory, and never fermentative. It can grow in the absence of oxygen, with NO3 as the respiratory electron acceptor. It does not require organic growth factors, and can use over seventy-five organic compounds for growth.

Causes and Targeted audience

Causes -

Pseudomonas are caused by a free-living bacteria, that are found widely in soil and water. They favor moist areas. Only a few of the many species cause disease.

Target audience -

Healthy people are usually not at risk of infection. People who already have a weakened immune system because of another illness or condition are at a higher risk of infection. This is especially true for patients who are hospitalized for an extended period of time. pseudomonas can be spread in hospitals via the hands of healthcare workers or by hospital equipment that is not properly cleaned.

Diagnosis and Treatment

A diagnosis is made by sending a sample of pus, blood, or tissue to a laboratory. The laboratory will then test for the presence of Pseudomonas. Pseudomonas are treated with antibiotics. Unfortunately, many hospital infections are becoming more difficult to treat. These bacteria have developed the ability to adapt and overcome antibiotics in their environment.


may cause aneurysms, cardiac complications such as heart failure. septic shock and death. can cause several different eye infections. May effect the GI tract, also you can have severe diarrhea.


Pseudomonas can be spread several different ways, which has through water and soil, also often occurs in the hospital in moist areas such as the sinks, and urine receptacles. The cross infection is transmitted from patient to patient through the hands of medical personnel usually in burn, urinary tract infection and neonatal intensive care units.
