Bacteremia is a presence of bacteria in blood. Penetration into blood of foreign microorganisms happens through the injured mucous membranes, skin sites, and also at pathological changes of vascular system, lymph nodes, existence of an infection, etc.

Presence of bacteria at blood is serious complication of infectious diseases (meningitis, pneumonia), catheterizations, various operations (especially on mucous membranes), hits of foreign bodys in veins or arteries.

Body resistance of the patient and virulence of microorganisms (productive capacity, toxigenicity, infectivity) plays a significant role in the speed of distribution and reproduction of bacteria to blood.

Bacteremia can cause serious effects, for example:

  • Sepsis (blood poisoning at long presence of bacteria at blood)
  • Septic shock (at a high probability of death)
  • Osteomyelitis
  • Endocarditis
  • Emergence of the secondary centers of bacteria in an organism at considerable distance from the place of emergence (because of ability of microorganisms to use blood for the advance).

For detection of bacteremia bacteriological research, and also a blood bacterioscopy in certain cases is used. In many cases bacteremia successfully to be treated by modern antibiotics, and also antimicrobic drugs.
