what is haemolysis used to assess? assess the ability of bacteria to lyse erythrocytes to access iron.


use a blood agar (enriched medium)


what are the 3 types of haemolysis? Alpha - incomplete produces green zone of lysis.


Beta - complete destruction clear zone of lysis.


Gamma - absence of any haemolysis.
