Paenibacillus larvae

Heyndrickx, M. Vandemeulebroecke, K. Hoste, B. Janssen, P. Kersters, K. Devos, R Logan, N. A. Ali, N. Berkeley, R. C. W. Reclassification of Paenibacillus (Formerly Bacillus) Pulvifaciens (Nakamura 1984) Ash et al. 1994, a later subjective synonym of Paenibacillus (Formerly Bacillus) larvae (White 1906) Ash et al. 1994, as a subspecies of Paenibacillus-larvae, with emended descriptions of Paenibacillus-larvae as Paenibacillus-larvae subsp larvae and Paenibacillus-larvae subsp pulvifaciens. Int. J. Syst. Bacteriol. 1996, 46, 270-279. 

Nemorosone (58), and chamone I (69), isolated from floral resins and trunk latex of Clusia grandiflora respectively, showed pronounced antibacterial activity on honeybee pathogens Paenibacillus larvae and Paenibacillus alvei in TLC bioassay [9]. These compounds are structurally similar, differing only the degree of prenylation. Chamone II and methyl ethers of nemorosone and chamone I were inactive and this suggest that the presence of an enol functionality is necessary for antibacterial activity in these molecules.
