Biocidal properties of maltose reduced silver nanoparticles against American foulbrood diseases pathogens

Abstract

Bee disease caused by spore-forming Paenibacillus larvae and Paenibacillus alvei is a serious problem for honey production. Thus, there is an ongoing effort to find an effective agent that shows broad biocidal activity with minimal environmental hazard. in this study, the biocidal effect of maltose reduced silver nanoparticles (AgNPs) is evaluated against American foulbrood and European foulbrood pathogens. the results demonstrate that the maltose reduced AgNPs are excellent short and long-term biocides against P. larvae isolates. the long-term effect suggests that the Ag+ ions are released from the AgNPs with increasing time in a controlled manner.
