Antibacterial Effect of Bee Venom on Panibacellus larvae causing American Foul Brood (AFB) in Honey Bee: Invitro st.

The antibacterial activity of bee venom and tylosin was evaluated against of Paenibacillus larvae, the causal agent of American Foulbrood (AFB) disease in honey bee colonies Apis mellifera L which was identified by using biolog assay, and characterized chemically and microscopically. Bee venom showed more antibacterial effect against AFB with Minimal inhibitory concentration (MIC), and MBC in BHIT which was 0.680.011mg/ml, and 0.820.009 consequently. While, mean MIC and MBC values of tylosin was 2.520.16mg/, and 3.50.18 consequently
