Transmission of American Foul Brood by Package Bees

Abstract
In May, 1965, nine 1-kg. packages of honeybees were shaken from healthy colonies (group A), and seven from colonies infected with American foul brood (group B). They were then transported from southern British Columbia to Beaverlodge, Alberta, and installed in sterile equipment with new frames and foundation. Six weeks after installation the 8 colonies remaining from group A remained free of A.F.B., but 4 of the 6 remaining in group B were infected. Rigid inspection of the colonies from which package bees are shaken is therefore recommended, together with preventive feeding on installation, in order to prevent the spread of A.F.B, to disease-free areas.
