American foul brood (caused by Bacillus larvae) was recorded for the first time in Argentina in 1989. The identification of the causative agent was based on disease symptomatology, morphological characters, pathogenicity tests and physiological and biochemical reactions. Studies by scanning electron microscopy showed the occurrence of large flagellar bundles of Bacillus larvae strains growing in biphasic BL medium. An electron microscope survey of the surface configuration of bacterial spores was also made.
