Improved haemolysis test for listeria identification
The detection of the haemolytic activity is fundamental to the identification of Listeria species (in particular L. monocytogenes and L. ivanovii).
The haemolysin test is simply performed by adding 1 drop of the specially stabilized sheep red blood cells comprising the haemolysin reagent to the last well (well 12) of the Microgen® Listeria ID test panel. If the organism being identified produces haemolysin, the red blood cells will rapidly be lysed and the cellular contents released into the suspending medium and the contents of the well will appear as a homogeneous red/ brown solution.
