Infectious diseases. 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 ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 1][ 2][ 3] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung. [ 4][ 5] In most cases patients ...
Staphylococcus aureus. Colorized scanning electron micrograph of a human neutrophil ingesting MRSA. Methicillin-resistant Staphylococcus aureus ( MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans.
Acute septic arthritis, infectious arthritis, suppurative arthritis, pyogenic arthritis, [ 4] osteomyelitis, or joint infection is the invasion of a joint by an infectious agent resulting in joint inflammation. Generally speaking, symptoms typically include redness, heat and pain in a single joint associated with a decreased ability to move the ...
Septic shock is a subclass of distributive shock, a condition in which abnormal distribution of blood flow in the smallest blood vessels results in inadequate blood supply to the body tissues, resulting in ischemia and organ dysfunction. Septic shock refers specifically to distributive shock due to sepsis as a result of infection.
Infectious diseases. Group A streptococcal infections are a number of infections with Streptococcus pyogenes, a group A streptococcus (GAS). [ 1] S. pyogenes is a species of beta-hemolytic Gram-positive bacteria that is responsible for a wide range of infections that are mostly common and fairly mild. If the bacteria enters the bloodstream, the ...
In patients with sepsis, septic shock, or multiple organ dysfunction syndrome that is due to major trauma, the rs1800625 polymorphism is a functional single nucleotide polymorphism, a part of the receptor for advanced glycation end products (RAGE) transmembrane receptor gene (of the immunoglobulin superfamily) and confers host susceptibility to ...
Infectious disease. A staphylococcal infection or staph infection is an infection caused by members of the Staphylococcus genus of bacteria. These bacteria commonly inhabit the skin and nose where they are innocuous, but may enter the body through cuts or abrasions which may be nearly invisible. Once inside the body, the bacteria may spread to ...
