Correlation between scores for the FKB Assay (freeze-killed brood assay, scored for complete removal after 24 h) and Z10-C33 Assay (scored as uncapping or removal after 24 h) for 10 colonies of different origins. A significant positive correlation between colony responses to the two assays was observed.
