Mrsa Brain Infection
Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
Wrong word: "normal" isn't really the proper descriptor - serious infections are never normal. Mrsa is, however, a *common* problem in nursing homes -- unfortunately. Good facilities are always on the lookout for infections of any kind in their residents, and when they find them, they treat them promptly. ...Read more
A bad type.: Mrsa is a potent strain of staph bacteria that worries doctors because it is resistant to the antibiotic methicillin, which for many years was the single best treatment for staph infections. It is usually treatable with other antibiotics, such as Bactrim (sulfamethoxazole and trimethoprim) or doxycycline, but such infections can be very virulent and contagious. ...Read moreSee 1 more doctor answer
Not always: The most common cellulitis pathogens (bacteria) are beta-hemolytic streptococci (groups a, b, c, g, and f) and staphylococcus aureus, including methicillin-resistant strains (mrsa). There are gram-negative aerobic bacteria that are identified in a minority of cases. Fungal infections can also cause cellulits. ...Read moreSee 3 more doctor answers
Staph aureus: We are all colonized with staph aureus. Whether or not we become infected with these organisms depends on multiple different factors. The ones that are in your cat are the same as the ones in your gut, or in your nasopharynx or on your skin. They have the same disease producing mechanisms. Whether they will infect you is problematic. ...Read more
Yes: Some patients become colonized with MRSA and are at risk for recurrent infections. This can be overcome with a series of chlorhexidene gluconate cleansing treatments, mupiricin ointment to the nares for a number of days and antibiotics as indicated. 2 negative cultures of the nares are felt to indicate the MRSA is resolved. ...Read more
Tick + MRSA =Maybe: Alea, I do not know for sure. We know mosquitos may transmit disease by feeding on multiple hosts. Mrsa is a resistant form of a common bacteria that lives on the skin of humans. Unfortunately, 50% or more have some form of MRSA living on their skin. I think it more likely a tick might break the skin and allow entry and possible infection by the MRSA that was already living outside on the skin. ...Read more
Staph infection: Unlikely to be spread by kissing, but once you have been colonized with this by kissing or other nose-to-hand-to-nose activities, the organism colonizes your skin and subsequent breaks in skin can lead to infection. ...Read more
How to distinguish axillary lymphedenitis staph infection from intriginous yeast infection of armpit?
Not very: It is very unlikely that any urine infection will be passed from one person to another. Nonetheless, and especially with certain kinds of staph, it is prudent to wash your hands whenever in contact with an infected person as the same staph may be present on the person's skin that is in the urine. ...Read more
Does infection spread through the bloodstream, such as a bacterial infection on ankle can spread to an ear infection?
Bacteremia: Infections can spread through the blood stream - when you hear the word "Sepsis" that implies a bacteria is in the blood stream and causing havoc on the body. Could an infection that started in the ankle get into the blood stream? Sure. Once it's in the blood stream could it seed other sites? Sure. If you didn't have high fever and signs of blood infection then I doubt your ear infection is relate ...Read moreSee 1 more doctor answer
Yes: Some people carry staph in their nasal passages. This is usually easily treated if present. If you are having recurrent staph skin infections, ask your doctor about treating your nose too. Staph can also cause sinus infections, but this is usually only true in people with chronic sinus disease, not your average sinus infection. ...Read moreSee 1 more doctor answer
My husband has frequent MRSA infections.we just found out by MRI of the brain that he has a cyst in his brain. Could he get MRSA in that cyst?
Brain Cyst: Without knowing more about the cyst (i.e. is it congenital or is it acquired?) then, I'd say it's going to be hard to be able to accurately predict but he will need to be particularly careful since he is diabetic and this by itself is a risk factor for more easily contracted infections of ALL types and much longer healing times. ...Read more
Does encephalitis just happen at any time? The virus you had in the past is dormant in your system then transfers and infects the brain of some people? Or does it more commonly happen in the new infections of the virus' ?
Confusing question: The wording of your question is hard to follow. That said, there are some basics I can state. Most encephalitis viruses burn out and are essentially eliminated by the immune system.There transfer process is type specific, some in saliva during the illness, some by mosquitoes, once healed, you do not pass the virus to others. ...Read more
I was first diagnosed with tick borne encephalitis in 2009. Still get sick all the time. Now have brain damage as a result of the infection.?
Sorry to hear that: Unfortunately, encephalitis contracted from any source (ticks, mosquitos, etc.) can result in neurological dysfunction. If you were treated for the appropriate tick illness, there should not be any remaining infective agent, but it is possible that your immune system may be slightly disrupted. See you doctor for a reevaluation. ...Read more
Healthy living: Bacterial encephalitis is uncommon these days thanks to healthy living and nutrition, getting bad teeth fixed right away, and getting treated promptly for sinusitis or ear infections. Bronchitis, pneumonia, endocarditis etc can spread in the blood stream and need to be treated aggressively to avoid seeding. Viral (herpes, hiv) or fungal brain infections are special situations - ask your doctor. ...Read moreSee 1 more doctor answer
CSF tests, imaging: While there are certain blood test results or MRI findings that raise the suspicion for infection, a definitive diagnosis often requires a lumbar puncture for analysis of cerebrospinal fluid. That being said, in many cases we will treat infections empirically just based on clinical suspicion, especially if the patient is presenting with seizures or other worrisome signs. ...Read moreSee 1 more doctor answer
Yes, not always : Depends on the type of infection. A larger abscess will be detected. More diffuse infections such as meningitis may reveal characteristic suggestive of an infection. Usually need to combine clinical history, exam, blood tests, CSF analysis +/- ct/mri to make diagnosis of a brain infection. ...Read more
CMV retinitis/enceph: CMV is a virus that we're infected with usually before adulthood. Once infected it stays latent w/in us ; our immune system keeps it in check. If our immune system is altered (w/hiv, or transplant treated w/meds suppressing immunity) virus reactivates ; causes problems. This is a serious infection that needs specific therapy. You need to see an id specialist. If you havent been, test for hiv. ...Read more
Yes: Yes, but this not common. Evidence suggests the infection is not spread by direct extention but through the blood. Signs of brain infection include: unremitting fever, nausea, vomiting, and significant headache. In children, it is more common to have direct extension into the orbit. ...Read moreSee 1 more doctor answer
Sinus infection: Will it? Probably not. Could it. Yes but this is extremely rare. See your doctor if you have persistent sinus infectious symptoms. ...Read more
Isit possible to get a brain infection if someone shuts a dirty, dust door a few inches from your face?
Virtually never: The brain is protected from infection by many barriers: the skin of the head, the skull, nasal passages have mucus, the nasal mucosa has immune system cells, and inside the head there are protective membranes. It is almost impossible to inhale something as you describe and have it get through these barriers to cause an infection in the brain. ...Read more
What steps can I take to make a sinus rinse as safe as possible? ("fatal brain infection" is freaking me out a little.)
Sinus rinse: Hello, when you are making your sinus saline solution, use distiller or boiled water. This will assure that their isn't any bacteria or microbes within the solution you are using to rinse your nose. Or you could purchase a can of saline spray in a premixed pressurized can. This also would be free of contaminants. ...Read more
Viral cultures, etc: The diagnosis is mostly done by tissue and peripheral blood leukosytes. These can take weeks. Other tests, like urine and saliva are not reliable, and ab titers can take 4 weeks. For CNS infections like viral meningitis and encephalitis, PCR testing provides rapid, sensitive, and specific identification of CMV and other viruses. ...Read more
Viral meningitis lke: The symptoms of this are probably like those of any viral meningitis, and consist of fever, headache, nausea, vomiting, malaise, anorexia, abdominal pain and diarrhea. This could also have CSF lymphocytes, higher protein, and glucose. This usually just needs supportive care. If the brain itself is involved, there can be altered consciousness, seizures, and focal neurologic findings. ...Read more
