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 clinical presentations of anaerobic bacteremia are not different from those observed in aerobic bacteremia, except for the infection's signs observed at the portal of entry of the infection. It often includes fever, chills, hypotension, shock, leukocytosis, anemia and disseminated intravascular coagulation.
The most frequent source of bacteremia due to Peptostreptococcus are infections of the oropharynx, lower respiratory tract, female genital tract, abdomen, skin, and soft tissues. Recent gynecological surgery, immunosuppression , dental procedures, infections of the female genital tract, abdominal and soft tissue along with gastrointestinal ...
Some symptoms include blisters, tachycardia, swelling, and jaundice. [47] C. perfringens is most commonly known for foodborne illness but can translocate from a gastrointestinal source into the bloodstream which causes bacteremia. C. perfringens bacteremia can lead to toxin-mediated intravascular hemolysis and septic shock. [48]
Diagnosis is by a swab of the affected area for laboratory testing. A Gram stain is performed to show Gram-positive cocci in chains. Then, the organism is cultured on blood agar. The rapid pyrrolidonyl arylamidase (PYR) test is commonly used, wherein a positive reaction confers a presumptive identification of group A beta-hemolytic streptococci ...
Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.
It can cause peritonitis, [6] endophthalmitis, [7] sepsis and bacteremia. Similar symptoms although also very rare can be seen by infections of P. luteola. [8] P. plecoglossicida is a fish pathogenic species, causing hemorrhagic ascites in the ayu (Plecoglossus altivelis). [9] P. anguilliseptica is also a fish pathogen. [10]
B. henselae can be associated with bacteremia, bacillary angiomatosis, and peliosis hepatis in HIV patients, and bacteremia and endocarditis in immunocompetent and immunocompromised patients. [6] Symptoms may include fatigue, headaches, fever, memory loss, disorientation, insomnia, and loss of coordination.
