Septicemia

Medical Definition:	Systemic disease associated with the presence and persistence of pathogenic microorganisms or their toxins in the blood. (Dorland, 27th ed)
Guide Notes:	a type of sepsis; GEN or unspecified only: prefer BACTEREMIA; FUNGEMIA; PARASITEMIA or VIREMIA; HEMORRHAGIC BACTEREMIA, a Pasteurella infect, is also available

Septicemia Categories.

	Fungemia - The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.
	Parasitemia - The presence of parasites (especially malarial parasites) in the blood. (Dorland, 27th ed)
	Sepsis Syndrome - A systemic response to infection, defined as hypothermia or hyperthermia, tachycardia, tachypnea, a clinically evident focus of infection or positive blood cultures, one or more end organs with either dysfunction or inadequate perfusion, cerebral dysfunction, hypoxemia, increased plasma lactate or unexplained metabolic acidosis, and oliguria. It is one of the most common causes of adult respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, ADULT). (Segen, Dictionary of Modern Medicine, 1992) While usually related to infection, it can also be associated with noninfectious insults such as trauma, burns, pancreatitis. (JAMA 1995;273(2):155-6)
	Shock, Septic - Shock due to circulatory insufficiency caused most commonly by gram-negative BACTEREMIA. It is less often the result of the persistent presence of other micro-organisms in the blood (FUNGEMIA; VIREMIA); in rare instances, it is caused by gram-positive organisms, but with different symptomatology.
	Viremia - The presence of viruses in the blood.
