Causes of bacteremia infection

The penetration of the pathogen into the bloodstream is celebrated in many infectious diseases and is required or possible component of their development.

Light, temporary bacteremia may occur even when a person clenches his jaw, because bacteria living on the gums around the teeth are in the blood. Bacteria often enter the bloodstream from the intestines, but they quickly destroyed with the passage of blood through the liver.

The number of microorganisms per unit volume of blood depends on the virulence of the pathogen and body resistance of the patient. Prolonged and severe bacteremia usually formed generalized and, in particular, a septic form of infectious process.

Symptoms of bacteremia infection

Symptoms of bacteremia infectionBecause with a small number of the bacteria the body can often resolve quickly, symptoms temporary bacteremia occur in rare cases. However, once sepsis develops, occurs chills, increased body temperature, there is a weakness, nausea, vomiting and diarrhea.

If not treated, the infectious agent is spread throughout the body and formed the so-called metastatic foci of infection.

The result can be meningitis inflammation of the meninges, pericarditis — inflammation of outer lining of the heart, endocarditis is an inflammation of the inner lining of the heart, osteomyelitis — inflammation of bone. In sepsis throughout the body may experience abscesses (accumulations of pus).

Diagnosis of bacteremia

A person who has an infection in any organ, suddenly increased body temperature. If sepsis develops, usually significantly increases the number of leukocytes in the blood. To identify the “perpetrator” of the microorganism that produces the blood culture. However, bacteria in culture of blood it is difficult to specify, especially if the person takes antibiotics. To take planting material of sputum from the lungs, urine, excreted from the wounds and from the places of insertion of catheters.

Treatment for bacteremia infection

Bacteremia associated with surgery or the insertion of a catheter into the urinary tract, usually requires no treatment, especially if the catheter is quickly removed. However, before performing such procedures to people with high risk of development of inflammation in response to bacteremia, such as patients with disease of the heart valves or a weakened immune system, prophylactically prescribe antibiotics.
