You can't sterilize blood as it would hemolize. Blood is sterilized aseptically when it is purchased-meaning the animal (lets say a sheep) is killed in a certain way to ensure this happens. So the blood in your blood agar plate has already been aseptically sterilized
It depends on the type of blood agar you are using. Blood agar generallly means whatever agar you are using + 5-10% of some type of mammalian blood (sheep, horse, rabbit, etc). I generally use TSA + 5% Sheep blood or Brucella Agar + 5% Horse blood, for instance.
Streptococcus is commonly found in most routine cultures using blood agar plates. The medium is most commonly called BAP, sheep's blood agar or SBA for short.
Many pathogens either fail to grow entirely or exhibit morphologies and hemolytic patterns on human blood agar that confound colony recognition. Availability of sheep blood is one reason (Need not to take consent to draw blood). Safety (free from HIV, HBV or HCV like organisms), another important reason. Blood from specially breed sheep for microbiological purpose are free from antibiotics which interrupt the growth of bacteria. Because of hemolysis which occur more frequently than to other animals blood, may be a reason but, not sure.
Yes, sheep blood agar is generally safe to touch. It is a solid growth medium commonly used in microbiology laboratories to culture bacteria. However, as with any biological material, it is important to practice good hygiene and follow proper lab safety protocols to minimize the risk of contamination or infection.
