Who Is More Susceptible To Lung Problems Caused By Pseudomonas Aeruginosa
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Common in the ICU: It is not common to get this infection in a normal host, that is someone who is healthy otherwise. This kind of pneumonia is fairly common in patients who become very ill from some other problem are require support in the intensive care unit, who otherwise have weakened immune systems, or who have cystic fibrosis which is a genetic disease, involving abnormally thick mucous in the lung. ...Read moreSee 1 more doctor answer
Not really: Pseudomonas is a very dangerous bacteria that infects those who are chronically or critically ill . ( such patients with cystic fibrosis or in the intensive care unit ) it is a it needs to be treated with antibiotics that are active against this germ and that often must be given iv. Sometimes when prolonged therapy is needed it can be completed at home, under medical supervision. ...Read moreSee 2 more doctor answers
My coworker has pseudomonas aeruginosa that has caused a corneal ulcer. Should i be worried of contracting it as well?
Yes: Polymyxins are a very old class of antibiotics. They tend to have kidney and nervous system toxicity, and because they are very old the exact effective doses of these drugsis not well known. Still given problems with bacterial antibiotic resistance, sometimes these agents are used when a highly resistant bacteria is encountered. Colistin the one most often used can be given via inhalation or iv. ...Read moreSee 1 more doctor answer
Infection or coloniz: No, it is uncommon to have pseudomonas in the respiratory tract if you are a non-hospitalized, otherwise normal individual. If you have some immune deficiency, or if the thorascopy was not done with sterile instruments, it is possible, but still unlikely. ...Read moreSee 1 more doctor answer
Sometimes: Quinilones in the past were very effective against pseudomonas, however because of their widespread and some might say, excessive use in the hospital and community many strains of pseudomonas are now resistant to these antibiotics. They still retain effectiveness in some cases, and specific testing of the germ grown from the patient (culture results) can determine if this is true in a given case. ...Read more
Probably not: When you have cancer, your immune system is compromised or lower, and this means you are more susceptible to developing an infection. However, it is not specifically to pseudomonas species per se. But, in general, you need to know the cancer type and what the treatment is, since some treatments (like chemotherapy), also decrease your ability to fight off infections effectively. ...Read moreSee 1 more doctor answer
Yes and no: Pseudomonas can be transmitted differently - contact exposure, airborne. Also, it may live on some of us without causing any disease, but when local immunity diminishes, it may start causing a problem. Skin infections caused by pseudomonas mandate usual hygiene measures such as hand washing, using protective wear, disposal of infected materials etc. But not 100% guarantee of protection. ...Read moreSee 1 more doctor answer
Not primary: Susceptibility to pseudomonas is observed when the normal defenses we have against infection are broken down, for example when a patient is very ill in the intensive care unit on a ventilator or breathing machine) mostly this is an acquired problem. However in cystic fibrosis, which is a genetic disease there is a particular tendency to get infected with this bacteria. ...Read moreSee 1 more doctor answer
Later in life: Patients with cystic fibrosis often get these bacteria in their airways by adulthood. The vast majority of adult CF patients have airways colonized with pseudomonas aeruginosa (pa). Younger patients (kids) tend not to have pa in their airways, but that can vary. ...Read moreSee 2 more doctor answers
post op wound culture was positive for- elizabethkingia meningoseptica, and pseudomonas aeruginosa, what kind of bacteria are these and are they bad?
Unfortunately, yes: These are both serious gram negative pathogens. E.meningoseptica is often resistant to usual gram negative agents except piperacillin, but are sensitive to vancomycin and rifampin and often sensitive to quinolones and bactrim (sulfamethoxazole and trimethoprim). What antibiotics are you treated with? ~13% of hospital-acquired pseudomonas infections are multi-drug resistant. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3841494/ ...Read moreSee 2 more doctor answers
By changing genes: This is not completely understood, but there is experimental evidence from animal experiments and such, that the pseudomonas grown in a low phosphate environment will respond on changes in what genes the germ activates. These changes lead the bacteria to make chemicals that increase its ability to grow and cause damage. In patients with low phosphate levels this may mean > risk of infection. ...Read moreSee 1 more doctor answer
