Clostridioides difficile infection[ 5] ( CDI or C-diff ), also known as Clostridium difficile infection, is a symptomatic infection due to the spore -forming bacterium Clostridioides difficile. [ 6] Symptoms include watery diarrhea, fever, nausea, and abdominal pain. [ 1] It makes up about 20% of cases of antibiotic-associated diarrhea. [ 1]
Peptoclostridium difficile [ 3] Clostridioides difficile ( syn. Clostridium difficile) is a bacterium known for causing serious diarrheal infections, and may also cause colon cancer. [ 4][ 5] It is known also as C. difficile, or C. diff ( / siː dɪf / ), and is a Gram-positive species of spore -forming bacteria. [ 6]
T 3 is the more metabolically active hormone produced from T 4.T 4 is deiodinated by three deiodinase enzymes to produce the more-active triiodothyronine: . Type I present in liver, kidney, thyroid, and (to a lesser extent) pituitary; it accounts for 80% of the deiodination of T 4.
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
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 ...
Clostridioides difficile toxin A ( TcdA) is a toxin produced by the bacteria Clostridioides difficile, formerly known as Clostridium difficile. [ 1] It is similar to Clostridium difficile Toxin B. The toxins are the main virulence factors produced by the gram positive, anaerobic, [ 2] Clostridioides difficile bacteria.
The Rh blood group system is a human blood group system. It contains proteins on the surface of red blood cells. After the ABO blood group system, it is the most likely to be involved in transfusion reactions. The Rh blood group system consisted of 49 defined blood group antigens [ 1] in 2005. As of 2023, there are over 50 antigens among which ...
The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination between them", [1] and include the common ABO and Rh ...
