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 infection can become ...
Severe sepsis causes poor organ function or blood flow. [9] The presence of low blood pressure, high blood lactate, or low urine output may suggest poor blood flow. [9] Septic shock is low blood pressure due to sepsis that does not improve after fluid replacement. [9] Sepsis is caused by many organisms including bacteria, viruses, and fungi. [10]
Maternal infections account for 2 to 4% of all clinically diagnosed S. pyogenes infections. [9] The risk of sepsis is relatively high compared to other bacterial infections acquired during pregnancy, and S. pyogenes is a leading cause of septic shock and death in pregnant and postpartum women. [10]
Streptococcal toxic shock syndrome is a rapidly progressing infection causing low blood pressure/shock and damage to organs such as the kidneys, liver and lungs. This type of toxic shock has a ...
Health agencies are issuing warnings to parents about invasive group A streptococcus (iGAS), a common bacterium that usually causes mild illness but can sometimes result in severe cases and even ...
Invasive group A streptococcal bacteria “can cause a range of illnesses, from pharyngitis (i.e., strep throat) and skin and soft tissue infections to uncommon but severe diseases such as sepsis ...
Streptococcus bovis is a group of strains of Gram-positive bacteria, originally described as a species, [5] [6] that in humans is associated with urinary tract infections, endocarditis, sepsis, [7] and colorectal cancer. [8] S. bovis is commonly found in the alimentary tract of cattle, sheep, and other ruminants, [9] and may cause ruminal acidosis.
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 ...
