Pseudomonas luteola is an uncommon organism that can cause infections in humans who have already had their health compromised. This lesson will explain what pseudomonas luteola is, as well as symptoms, susceptibility, and treatment associated with the infection.

Definition of Pseudomonas Luteola

Pseudomonas luteola (formerly known as chryseomonas luteola) is a bacterium that usually presents itself in the body of people with other infections or disorders. It is an aerobic, gram negative rod with a yellowish pigment. Its classification is important in order to know what antibiotics will be effective. The report of occurrences is extremely rare and is usually presented as septicemia, endocarditis, meningitis, peritonitis, or ulcer infections. It is also associated with hospitals and invasive procedures such as surgeries, catheters, and prostheses. Pseudomonas luteola is diagnosed by culturing the blood or culturing the organism from an infected site such as a wound with drainage.

Symptoms of Pseudomonas Luteola

The symptoms of pseudomonas luteola are broad and not always the same. However, with any infection there is usually a fever, chills, and excess fluid buildup (ex. respiratory secretions or wound drainage). Symptoms can be dependent on the source of the infection.

For example, a fifty year old male was hospitalized after surgery for a broken foot. Unfortunately, he developed respiratory distress and required intubation and a ventilator for several days. Pneumonia acquired from the ventilator developed as well as bacteremia. Therefore, symptoms associated with the infection included a rapid heartbeat, fever, confusion, and chest pain. A culture of blood was taken and pseudomonas luteola was present.

Another different presentation could be a thirty year old male who cut his leg while working outside. When seen by the doctor, he reported some nausea, vomiting, diarrhea, and fever. The leg that had been cut was red, swollen, and tender to touch with some pus-like drainage. A culture of the wound was taken and pseudomonas luteola was present.

Susceptibility of Pseudomonas Luteola

Antibiotics must be used in order to rid the body of the pseudomonas luteola bacteria. There are many types of antibiotics available so the right ones have to be chosen to fight the infection. Some bacteria are resistant to certain antibiotics, so several must be chosen that are effective. In the case of this infection which is usually present with other health issues, several antibiotics will be used. Tests have shown that pseudomonas luteola is sensitive to third-generation cephalosporins or extended spectrum cephalosporins, as well as aminoglycosides, imipenem, and fluoroquinolones. That means that they are effective in treating the infection. The bacteria are resistant to first and second generation cephalosporins, tetracyclines, and ampicillin. Therefore, those types of antibiotics cannot be used.

Pseudomonas Luteola Treatment

It was mentioned earlier that pseudomonas luteola is a gram negative rod. This classification helps in choosing the correct antibiotic. Examples of third generation cephalosporins that treat pseudomonas luteola are ceftazidime and cefoperazone. Examples of aminoglycosides include gentamicin and amikacin. The treatment of pseudomonas luteola will also be decided by recognizing underlying problems.
