Bacteremia is the presence of bacteria in the bloodstream that are alive and capable of reproducing. It is a type of bloodstream infection. [36] Bacteremia is defined as either a primary or secondary process. In primary bacteremia, bacteria have been directly introduced into the bloodstream. [37] Injection drug use may lead to primary bacteremia.
The incidence of anaerobic bacteria in bacteremia varies between 5% and 15%, [41] The incidence of anaerobic bacteremia in the 1990s declined to about 4% (0.5–12%) of all cases of bacteremias. A resurgence in bacteremia due to anaerobic bacteria was observed recently. [ 43 ]
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [4] [7] This initial stage of sepsis is followed by suppression of the immune system. [8] Common signs and symptoms include fever, increased heart rate, increased breathing rate, and confusion. [1]
Blood is normally sterile. [1] The presence of bacteria in the blood is termed bacteremia, and the presence of fungi is called fungemia. [2] Minor damage to the skin [3] or mucous membranes, which can occur in situations like toothbrushing or defecation, [4] [5] can introduce bacteria into the bloodstream, but this bacteremia is normally transient and is rarely detected in cultures because the ...
Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. [1] It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. [2] Ascites is most commonly a complication of cirrhosis of the liver. [1]
“Sepsis usually begins with an infection, for example in the chest, skin, urine or meningitis, but in the early stages symptoms can be vague and hard even for doctors and nurses to recognise.
Clostridium tertium bacteremia can cause fever, and directed antibiotic therapy is indicated. [3] C. tertium is commonly (but not universally) resistant to many β-lactam antibiotics such as penicillin and cephalosporin; clindamycin; and metronidazole; but it is susceptible to vancomycin, trimethoprim-sulfamethoxazole, and ciprofloxacin. [3]
Without antibiotic treatment, S. aureus bacteremia has a case fatality rate around 80%. [3] With antibiotic treatment, case fatality rates range from 15% to 50% depending on the age and health of the patient, as well as the antibiotic resistance of the S. aureus strain.
