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 ...
Streptococcus pyogenes is a species of Gram-positive, aerotolerant bacteria in the genus Streptococcus. These bacteria are extracellular , and made up of non-motile and non-sporing cocci (round cells) that tend to link in chains.
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 ...
Infections caused by the Strep A bacteria can be potentially life-threatening.
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 ...
The bacteria are commonly found in the throat and on the skin, and some people have no symptoms. Infections cause by Strep A include the skin infection impetigo, scarlet fever and strep throat ...
Similarly, group B streptococcus typically denotes Streptococcus agalactiae, although minor beta-hemolytic group B streptococci like S. troglodytidis exist. [15] While most streptococcal illnesses in humans originate from species adapted to humans, such as S. pneumoniae or S. pyogenes, there are zoonotic species capable of causing infections. [15]
