Streak stab is most commonly used when inoculating blood agar with hemolytic bacteria. The stabs expose the bacteria to a greater surface area of blood cells and will enhance the hemolysis effect.
first of all the method of stabbing the agar is no only for throat sample but can be for all specimen except for liquid samples such as urine. the second thing is by stabbing the loop, you can save your time to sterile the loop back. and the other thing is to make sure the loop are no hot anymore..
Yes, Haemophilus influenzae can grow on blood agar.
blood agar, as it provides essential nutrients and growth factors needed for the growth of fastidious bacteria. Additionally, the presence of blood in the agar helps to support the growth of these bacteria by providing additional nutrients.
Agar is generally made by mixing the powdered form with varying ingredients. The powder is based on seaweed extract for nutrient agar, and nutrient agar is generally a base for most other agars - eg. Horse Blood Agar is nutrient agar with horses blood added; Choc agar has defibrinated (cooked) horses blood added.
Blood agar is the agar most often used for throat cultures. It contains nutrients for bacterial growth and sheep's blood, which allows for the detection of hemolysis patterns that can help identify certain pathogens.
By stabbing the blood agar, the hemolysis will be easier to see and identify.

To make it semi-solid
No it does not pit blood agar I am curently studying Chromobcaterium violaceum and recently grew it on a sheep blood agar it did not pit it. Cv turned the agar a brown color.
Yes, Haemophilus influenzae can grow on blood agar.
blood and chocolate agar plates as well as in universities laboratory Nutrient agar plates are also provided

The cast of Blood Blood Blood - 2009 includes: Mark Melbower as Stabbing Guy 2 Jacob Van Benthem as Stabbing Guy 1
In chocolate agar , blood is lysed by temperature, from that differnt matrials which are helpful to some organisms are release from RBCs.. and from blood agar cells are not lysed and some organisms can not take their nutrients from unlysed RBCs... This is a main difference....
Blood agar contains red blood cells that can be hemolyzed by certain bacteria, allowing for the differentiation of bacterial species based on their hemolytic activity. Chocolate agar is made from heated blood agar which inactivates certain inhibitory factors, making it suitable for the growth of fastidious bacteria like Haemophilus influenzae.
Blood agar is enriched medium which are complex media to which an extra nutrient source (such as blood in this case) is added to encourage the growth of fastidious heterotrophs.
