    Septic shock is low blood pressure due to sepsis that does not improve after fluid replacement. [9] Sepsis is caused by many organisms including bacteria, viruses, and fungi. [10] Common locations for the primary infection include the lungs, brain, urinary tract, skin, and abdominal organs. [2]

  3. Bloodstream infection - Wikipedia

    en.wikipedia.org/wiki/Bloodstream_infection

    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 ...

    In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."

  6. Blood culture - Wikipedia

    A blood culture is a medical laboratory test used to detect bacteria or fungi in a person's blood.Under normal conditions, the blood does not contain microorganisms: their presence can indicate a bloodstream infection such as bacteremia or fungemia, which in severe cases may result in sepsis.

  7. Serology - Wikipedia

    en.wikipedia.org/wiki/Serology

    Serology is the scientific study of serum and other body fluids.In practice, the term usually refers to the diagnostic identification of antibodies in the serum. [1] Such antibodies are typically formed in response to an infection (against a given microorganism), [2] against other foreign proteins (in response, for example, to a mismatched blood transfusion), or to one's own proteins (in ...

  8. Seroconversion - Wikipedia

    en.wikipedia.org/wiki/Seroconversion

    In immunology, seroconversion is the development of specific antibodies in the blood serum as a result of infection or immunization, including vaccination. [1] [2] During infection or immunization, antigens enter the blood, and the immune system begins to produce antibodies in response. Before seroconversion, the antigen itself may or may not ...

    Neutrophils migrate from blood vessels to the infected tissue via chemotaxis, where they remove pathogens through phagocytosis and degranulation Inflammation is a process by which the body's white blood cells and substances they produce protect us from infection with foreign organisms, such as bacteria and viruses. The (phagocytes) white blood ...
