Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
Fungal sepsis accounts for approximately 5% of severe sepsis and septic shock cases; the most common cause of fungal sepsis is an infection by Candida species of yeast, [29] a frequent hospital-acquired infection. The most common causes for parasitic sepsis are Plasmodium (which leads to malaria), Schistosoma and Echinococcus.
Fungemia is the presence of fungi or yeast in the blood. The most common type, also known as candidemia, candedemia, or systemic candidiasis, is caused by Candida species. Candidemia is also among the most common bloodstream infections of any kind. [1]

Septicemic plague can cause disseminated intravascular coagulation and is always fatal when untreated. The other varieties of the plague are bubonic plague and pneumonic plague. [1]
Active viremia is caused by the replication of viruses which results in viruses being introduced into the bloodstream.Examples include the measles, in which primary viremia occurs in the epithelial lining of the respiratory tract before replicating and budding out of the cell basal layer (viral shedding), resulting in viruses budding into capillaries and blood vessels.
In contrast, Staphylococcus bloodstream infections are frequently acquired in a health care setting where they can enter the bloodstream through procedures that cause breaks in the integrity of skin, such as surgery, catheterization, or during access of long term indwelling catheters or secondary to intravenous injection of recreational drugs.
The final report of the U.K.'s infected blood inquiry was published on Monday, nearly six years after it began looking into how tens of thousands of people contracted HIV or hepatitis from ...
If the bacteria enters the bloodstream, the infection can become severe and life-threatening, and is called an invasive GAS (iGAS). [2] [3] Infection of GAS may spread through direct contact with mucus or sores on the skin. [2] GAS infections can cause over 500,000 deaths per year. [4]
