This is deeply upsetting. If gummy bears, peach rings and gummy worms are a few of your favorite sweet treats, we urge you to stop reading now. The way most gum-based candy is made might scar you forever. If youâve ever had a vegetarian friend turn down a fruit snack or cup of jello, you know itâs because many of those products are made with gelatin.
A micrograph depicting Streptococcus agalactiae bacteria. Colonial Morphology and Identification: Colonial morphology of S. agalactiae in culture is typically gray to whitish-gray in colour when grown on sheep blood agar.his picture shows one of these tests. It is called the CAMP test. S. agalactiae infection is diagnosed using samples collected from blood, urine or spinal fluid. To identify this pathogen, vaginal and rectal swabs are typically culture on sheep blood agar medium and are identified using the CAMP test (Figure 2).
Bacteria growing on blood agar can be classified in part on what they do to the red blood cells incorporated into the medium. Some bacteria produce hemolysins, enzymes that destroy red blood cells (hemo = blood, lysin = to split).Hemolysins can destroy the cells and release the hemoglobin into the medium.As the hemoglobin is exposed to the chemicals in the agar, its characteristic red color is altered. This type of hemolysis, alpha-hemolysis, turns the medium under the bacterial growth brown-green.emolysins can destroy the cells and release the hemoglobin into the medium.
