A blood culture is a medical laboratory test used to detect bacteria or fungi in a person's blood. Under normal conditions, the blood does not contain microorganisms: their presence can indicate a bloodstream infection such as bacteremia or fungemia, which in severe cases may result in sepsis. By culturing the blood, microbes can be identified ...
Streptococcus agalactiae is the most common human pathogen belonging to group B of the Lancefield classification of streptococci —hence the name of group B stretococcal (GBS). Infection with GBS can cause serious illness and sometimes death, especially in newborns, the elderly, and people with compromised immune systems.
Blood samples should be allowed time to form a clot at room temperature for 30–60 min. [6] CDC recommends a range of time to allow clot formation that was reasonably consistent, from a minimum of 30 min to 60 min maximum.
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 ...

It is a beta- hemolytic, catalase -negative, and facultative anaerobe. [1][2]
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]

The agency's main goal is the protection of public health and safety through the control and prevention of disease, injury, and disability in the US and worldwide. [4] The CDC focuses national attention on developing and applying disease control and prevention. It especially focuses its attention on infectious disease, food borne pathogens ...
