Bacteremia : causes, diagnosis and treatment

bacteremia - the presence in the circulation of bacteria.Harmful bacteria usually enter the blood from the affected organs, such as injury or infection from blood-sucking parasites.Bacteria in the blood often observed during infections.

Bacteria are released into the blood of a healthy organism, excreted through several hours with salivary gland, kidney, liver, phagocytosis, and humoral immunity factors.

When the body is weakened, microbes in the blood persist for much longer.If the human body actively resists bacteremia, he can get rid of microorganisms fairly quickly, but if the body's resistance is low, may develop sepsis or pyosepticemia.

bacteremia progresses and affects other organs, develop miliary tuberculosis (when the flow of active bacteria into the blood stream), osteomyelitis (typhoid fever), and many other complications.

reasons bacteremia

cause of bacteremia is the penetration of pathogens into the bloodstream via the respiratory tract, tonsils, intestinal wall.There is a short-ter

m bacteremia, it occurs after a tonsillectomy, removing decayed teeth and other procedures.

in infectious diseases (recurrent or typhus, tularemia) bacteremia promotes invasion of pathogens through damaged skin and mucous membranes.

bacteremia is characteristic for the following diseases: botulism, salmonellosis, brucellosis, paratyphoid fever, typhoid fever.

Diagnosis and treatment of bacteremia

To make an accurate diagnosis, the experts used the following methods:

  • bacterioscopy stained (leptospirosis, relapsing fever, malaria, spirochetosis) native or blood products;
  • bacteriological test - a blood test for culture media (bile broth with paratyphoid and typhoid fever);
  • biological method - to determine the disease specifically infect experimental animals, also infected with disease vectors (lice and various other arthropods, contamination of the blood made a person sick);
  • blood purification method using a bactericidal and bacteriostatic action of antibodies or destruction of microbes endothelial cells and leukocytes.

bacteremia mainly treated with antibiotics, is also used in the technique of inserting a catheter focus of inflammation.
