Volatile Acids from Honeybee Larvae Infected withBacillus Larvaeand from a Culture of the Organism

Abstract
An ether extract of honeybee larvae killed by Bacillus larvae contained several volatile organic acids, most of which were also present in an extract from an in vitro culture of the causative organism. The extracts of diseased larvae and the culture were characterized by highly odorous acids, including valeric, isovaleric, anteisovaleric, butyric and caproic acids, whereas healthy larvae were generally devoid of these compounds.
