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]
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.
Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
Astrovirus infection Electron microscopy, enzyme-immunoassay , immunofluorescence, and polymerase chain reaction: Supportive care No Babesia species Babesiosis: Giemsa-stained thin-film blood smear: Atovaquone and azithromycin. In life-threatening cases, exchange transfusion is performed. No Bacillus cereus: Bacillus cereus infection Culture ...
Dengue fever becomes more virulent during a second infection by means of antibody-dependent enhancement. After the first infection, macrophages display antibodies on their cell membranes specific to the dengue virus. By attaching to these antibodies, dengue viruses from a second infection are better able to infect the macrophages, thus reducing ...
The British Divers Marine Life Rescue charity has warned people who do get bitten are at risk of a condition called "seal finger". ... said: "It's a really nasty blood infection, it's horrible. It ...
The high level of cytokines causes sepsis-like symptoms which is life-threatening instead of helping to fight against the infection. [24] Those who have a high risk of sepsis during a leptospirosis infection are found to have the HLA-DQ6 genotype, possibly due to superantigen activation, which damages bodily organs. [21]
Because the bone marrow is the manufacturing center of blood cells, the suppression of bone marrow activity causes a deficiency of blood cells. This condition can rapidly lead to life-threatening infection , as the body cannot produce leukocytes in response to invading bacteria and viruses , as well as leading to anaemia due to a lack of red ...
