septicemia

(sĕptĭsē`mēə), invasion of the bloodstream by virulent bacteria that multiply and discharge their toxic products. The disorder, which is serious and sometimes fatal, is commonly known as blood poisoning. The invasive organisms are usually streptococcistreptococcus
, any of a group of gram-positive bacteria, genus Streptococcus, some of which cause disease. Streptococci are spherical and divide by fission, but they remain attached and so grow in beadlike chains.

, any of the pathogenic bacteria, parasitic to humans, that belong to the genus Staphylococcus. The spherical bacterial cells (cocci) typically occur in irregular clusters [Gr. staphyle=bunch of grapes].

 but may be any type of bacteria. Septicemia occurs most often in older people who have underlying disease that makes them more susceptible to the infection. The primary causes of septicemia are infection within the walls of the blood vessels, rapidly progressing tissue infections (osteomyelitis, cellulitis), virulent systemic disease (meningitis, typhoid), and local infections (abscess, carbuncle) that the defense mechanisms of the body are unable to contain. The microorganisms usually spread to other organs, such as the lungs, liver, and brain.

Symptoms of septicemia are fever (usually quite high), chills, low blood pressure, confusion, and rash; it often results in multiple organ failure if not treated promptly with antibiotics. The diagnosis can be confirmed with blood cultures for the organism or with blood tests for antibodies or high levels of white blood cells.
