Infective Endocarditis Coagulase-negative S. aureus: causes subacute disease similar to Streptococcus viridans. Accounts for 30% of IE associated with prosthetic valves. Streptococci: S. viridans: 50-60% of subacute IE cases. Group D streptococci: usually subacute and the third most common cause of IE. Streptococcus intermedius: acute and subacute infection. Causes 15% of all cases of IE. Group A, C and G streptococci: acute IE is similar to that with S. aureus. High mortality (up to 70%).

- Although Micrococcus-like organisms cause endocarditis infrequently (6), the description of 2 independent infections due to a new species in a short period is intriguing and suggests a specific pathogenicity, at least on prosthetic heart devices.

- Streptococcus pneumoniae is the most common cause of bacterial pneumonia. Streptococcus pneumoniae is the most common cause of bacterial pneumonia. People who suffer from chronic obstructive pulmonary disease (COPD) or alcoholism most often get pneumonia from Klebsiella pneumoniae and Hemophilus influenzae.t is characterized primarily by inflammation of the alveoli in the lungs or by alveoli that are filled with fluid (alveoli are microscopic sacs in the lungs that absorb oxygen). At times a very serious condition, pneumonia can make a person very sick or even cause death.

What is Chemoprophylaxis? One of the most common forms of chemoprophylaxis is called bacterial endocarditis (BE) prophylaxis. People who have had heart surgery, and especially who have any artificial valves or replacement of valves in the heart are at greater risk for developing a bacterial infection in the heart especially when they undergo any type of dental work.

Endocarditis - Topic Overview Endocarditis is an infection of the heart 's valves or inner lining. It occurs when germs get into the bloodstream and settle inside the heart, often on a valve. The infection is usually caused by bacteria. In rare cases, it is caused by fungi. This infection can damage your heart. It needs to be treated right away.ndocarditis is an infection of the heart 's valves or inner lining. It occurs when germs get into the bloodstream and settle inside the heart, often on a valve.

An Overview of Meningococcal Meningitis Bacteria and viruses are the two main causes of meningitis. The bacterium Neisseria meningitidis, also called meningococcus, causes meningococcal meningitis. In children and teens, meningococcus is the most common cause of bacterial meningitis.In adults, it is the second most common cause.our risk for meningococcal meningitis increases if you are exposed to the bacterium that causes it. Your risk also increases if you've had a recent upper respiratory infection. Babies, children, and teens are at greatest risk.

- Invasive streptococci cause joint or bone infections, destructive wound infections (necrotizing fasciitis) and myositis, meningitis and endocarditis. Two post streptococcal sequelae, rheumatic fever and glomerulonephritis, may follow streptococcal disease, and occur in 1-3% of untreated infections.

- Best Answer: Endocarditis is usually caused by bacteria. When symptoms are prevalent, blood cultures are done to detect what sort of bacteria is present. Many types of bacteria can cause endocarditis.Normally, blood flows smoothly through heart valves.But if they have been damaged, by some other medical condition, defense mechanisms (such as white blood cells) cannot enter the valves.f the heart valves are damaged, they may leak, causing regurgitation of blood. For example, if the mitral valve (between the left atrium and left ventricle) leaks, blood will leak back into the left atrium when the ventricle contracts. This reduces the efficiency of the heart contraction.

Subacromial bursitis Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

- Subacromial bursitis is a common cause of shoulder pain that is usually related to shoulder impingement of your bursa between your rotator cuff tendons and bone (acromion). Your subdeltoid bursa is less commonly inflamed shoulder bursa.

Necrotizing Fasciitis (Flesh-Eating Bacteria) Causes of Necrotizing Fasciitis. Necrotizing fasciitis is commonly caused by group A Streptococcus (GAS) bacteria. That's the same type of bacteria that causes strep throat.However, several types of bacteria, such as staphylococcus and others, have also been associated with the disease.Necrotizing fasciitis occurs when such bacteria infect the superficial fascia, a layer of connective tissue below the skin.owever, several types of bacteria, such as staphylococcus and others, have also been associated with the disease.

Low Back Pain Linked to Bacterial Infection Low Back Pain Linked to Bacterial Infection. New research suggests that some 40% of chronic lower back pain (CLBP) could be caused by bacteria, and that a significant percentage of people with lower back pain following a herniated disc and swelling in the spine could find relief by taking an antibiotic.

Basic researchâbiologyAutoaggregation and Coaggregation of Bacteria Associated with Acute Endodontic Infections Biofilms and microbial aggregates are a common mechanism for the survival of bacteria in nature. Microbial aggregates have been associated with intraradicular and extraradicular endodontic disease.

Bacterial Endocarditis Only those bacteria that are able to stick to the surface lining of the heart and to abnormal valves tend to cause endocarditis. The ability of these bacteria to stick to the surface lining is aided by a preexisting microscopic clot that often forms at these abnormal sites.

Causes of Infective Endocarditis Very frequently infective endocarditis is a complication of sepsis (a systemic inflammatory response to severe infection). The bacteria mostly adhere to valves and less frequently to parietal endocardium and artificial valves. Infective endocarditis can be caused by the following microorganisms:

- Heart infections, such as pericarditis, endocarditis and myocarditis, are caused when an irritant, such as a bacterium, virus or chemical, reaches your heart muscle. The most common causes of heart infections include: 1  Bacteria. 2  Viruses. 3  Parasites.

Endocarditis If endocarditis is not treated, the bacteria that cause endocarditis can form growths on or around the heart valves. The growths prevent the heart valves from opening and closing properly. This interrupts the normal blood flow through the valves and interferes with the heart's pumping action.

Antibiotic treatment of infective endocarditis due to viridans streptococci, enterococci, and other streptococci Infective endocarditis caused by viridans streptococci, enterococci or other streptococci accounts for at least 55-65% of all cases of native valve endocarditis in non-addicts.

- The heart of a person with endocarditis has clumps of bacteria and cells (vegetation) that form on the heart valves. This makes it harder for the heart to work properly. On occasions, the infection can spread to the kidneys, lungs, and brain. Abscesses can develop in the heart muscle in some cases.n infection of the endocardium causes endocarditis. The infection is generally caused by the bacteria streptococci or staphylococci. Endocarditis can be caused by fungi or other infectious micro-organisms, but very rarely.

Management of Bacterial Endocarditis Occasionally, bacterial endocarditis is caused by viridans streptococci that are moderately susceptible to penicillin. These patients should be treated with intravenous penicillin at a dosage of 18 million units every 24 hours for four weeks and with gentamicin for the first two weeks.ACEK ORGANISMS. Patients with endocarditis of a native valve caused by an organism in the HACEK group should be treated with ceftriaxone in a dosage of 2 g daily intravenously or intramuscularly for four weeks. Patients with infection of a prosthetic valve should be treated with ceftriaxone for six weeks.
