ANTIBACTERIAL EFFECTS OF ANATOLIAN PROPOLIS ON PAENIBACILLUS LARVAE

Paenibacillus larvae (P. larvae) is a pathogenic bacterium causing American Foulbrood Disease (AFB) in honeybee larvae. It necessary to develop alternative strategies for the control of this disease due serious colonies loses and use antibiotics. Recent studies are aimed at investigating natural fighting agents against P. In our study, it was demonstrate potential antibacterial efficacy ethanol extract Anatolian Propolis (EAP) strains PB35 SV35 which were isolated Turkey. The total phenolic content (TPC) flavonoid (TFC) EEAP determined as 181.73±5.20 mg Gallic Acid Equivalents (GAE)/g, 42.33±1.40 Quercetin (QE)/g, respectively. found that EAP contains different amounts ferulic, caffeic, coumaric acids, rutin, caffeic acid phenethyl ester (CAPE). activity by using agar-well diffusion, microdilution, Bioscreen C techniques. Minimal Inhibition Concentration (MIC) values 74.87 ?g/ml strain both microdilution teqnique. techniques, Bactericidal (MBC) evaluated 149 598.4 SV35, fact shows low concentrations bacteriostatic bactericide strains, spore-forming bacilli, AFB disease, suggests may be source control.
