What is culture negative bacterial endocarditis?
Endocarditis is an inflammation of the endocardium (part of the heart), and if it is bacterial, the cause for it is bacteria.
The part of the term culture negative, means that they tried to grow the bacteria in the lab after taking a blood sample, and were unable to get it to grow.
Yes as an opportunistic (secondary) infection when the immune system is fighting the flu virus and has trouble dealing with bacterial infections at the same time. Weakened immune systems can allow people to get bacterial infections more easily. But the person still must be exposed to the bacteria that causes the infection and inflammation of the inner lining of the heart (which is called the endocardium). Endocarditis also can affect the heart valves. Prevention is…
Streptococcus viridans is responsible for sub acute bacterial endocarditis. This is relatively a benign organism, which is responsible for dental caries. It can affect the damaged heart valves and cause the above mentioned condition. Which is very difficult to cure, once established. You have to give two grams of amoxicillin about one hour prior to dental procedure to prevent this condition in such patients.
Yes. The heart problems are caused by Bacterial Endocarditis which is an infection of the hearts inner lining (endocardium) and / or the heart valves. Bacterial Endocarditis occurs when bacteria enters the blood stream, either though Finger Nail Biting or dental procedures. The bacteria then lodges itself heart valves or other damaged heart tissue This will eventually lead to extensive heart damage which will in turn cause it to fail.
Cephalexin is typically used to treat bacterial infections and prevent heart valve infections. Bacterial infections that cephalexin can treat are sinus infections, irritations of the prostate, and skin infections (like cellulitis). Cephalexin is used for infants and children to treat the same infections seen in adults. It may also be given to people who are allergic to penicillin. Treatment of bacterial infections Prevention of heart valve infections (bacterial endocarditis).
The Gram positive bacterial cell wall is made up of thick peptidoglycan layer which is rich in Teichoic acids. These teichoic acids are negatively charged because of presence of phosphate in their structure. The Gram negative bacteria have an outer membrane composed of phospholipids and Lipopolysaccharides. The lipopolysaccharides impart a strongly negative charge to surface of Gram negative bacterial cells.
