12. Defnition:- Septicemia is the presence of
disease causing bacteria in the blood.
• presence of bacteria in bloodstream is called as
bacteremia.
• Untreated septicemia can quickly progress to
sepsis, which is a serious complication of an
infection characterized by inflammation
throughout the body.
• This inflammation can cause blood clots and
block oxygen from reaching vital organs,
resulting in organ failure and death in some
cases.

several industrialized nations have recently been
reported to be 50–100 cases per 100,000

sepsis.

15. Etiology
• Blood cultures are positive:
– 20–40% of Severe sepsis cases
– 40–70% of septic shock cases
• Of cases with positive blood cultures,
– 40% -gram-positive bacteria,
– 35% - gram-negative bacteria,
– 11 % - Polymicrobial
– 7% - fungi
– <5% - classic pathogens
