Abstract: | Antigens from four cultures ofO. graminis were compared immunoelectro-phoretically. Each culture produced a characteristic immunogram. More common antigens were found between the two cultures isolated from wheat or the two cultures isolated from oat than between a wheat and an oat isolate. Cell-wall antigens were the best reference antigens for serologic analysis of strain relationship.
O. graminis antisera were cross-reacted with antigens from a number of other species of fungi. Relatively few of these cross-reacted with antisera to cell-wall antigens whereas more cross-reacted with antisera to whole-cell antigens.Immunoelectrophoretic analysis of antigens from a range of isolates ofO. graminis indicates specific immunograms which can be determined and separated from the immunograms developed by all other fungi when tested againstO. graminis antiserum. Immunoelectrophoresis can therefore be used as an aid in determiningO. graminis. |
