Overview<\/strong><\/p>\n

Many microorganisms can grow in blood agar and when they do they respond in a different way according to whether they carry out the red blood cell lysis or not (hemolysis), which is produced by the effect of an enzyme called hemolysin.
\nThree types of hemolysis can be distinguished:<\/p>\n\n\n\n\n
\"\"<\/td>\n\"\"<\/td>\n\"\"<\/td>\n<\/tr>\n
Alpha hemolysis<\/b>
\nThis is a partial hemolysis and the area of growth appears surrounded by a green halo.<\/em><\/span><\/td>\n		 Beta hemolysis<\/strong>
\nIn this case the hemolysis is complete and the halo that surrounds the colonies is completely transparent.<\/em><\/span><\/td>\n		 Gamma hemolysis (not hemolysis)<\/strong>
\nThe microorganism in question cannot carry out the hemolysis and therefore there is no halo around the colony. <\/em><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The pure culture is inoculated by means of the loop streaking technique<\/a> on a blood agar plate.
\nAfter 24 hours of incubation observe the presence of hemolysis halos around the colonies and identify the type of hemolysis carried out by our microorganism.<\/p>\n\n\n\n\n
