Substances Inhibiting the Growth of Paenibacillus Larvae Larvae in Honeybee Colonies
The honeybee disease known as American foulbrood is a serious economic problem for beekeepers. It is caused by the bacterium Paenibacillus larvae subsp. larvae (formerly Bacillus larvae) (9). Honeybee larvae become infected by swallowing spores of P. larvae larvae that contaminate their food. After spores germinate in the midgut of a larva, the vegetative forms penetrate the tissue of the intes...
متن کاملIn vitro study of the antimicrobial activity of Brazilian propolis against Paenibacillus larvae.
The honey bee disease American foulbrood (AFB) is a serious problem since its causative agent (Paenibacillus larvae) has become increasingly resistant to conventional antibiotics. The objective of this study was to investigate the in vitro activity of propolis collected from various states of Brazil against P. larvae. Propolis is derived from plant resins collected by honey bees (Apis mellifera...
متن کاملRegional variation in composition and antimicrobial activity of US propolis against Paenibacillus larvae and Ascosphaera apis.
Propolis is a substance derived from antimicrobial plant resins that honey bees use in the construction of their nests. Propolis use in the hive is an important component of honey bee social immunity and confers a number of positive physiological benefits to bees. The benefits that bees derive from resins are mostly due to their antimicrobial properties, but it is unknown how the diversity of a...
متن کاملDetection of Paenibacillus larvae larvae spores in honey and diseased larvae Samples by culture and PCR
American foulbrood (AFB) is the most serious brood disease of the honey bee. Traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. The aim of this study is the detection of Paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and PCR. Therefore 54 samp...
متن کاملNew Paenibacillus larvae bacterial isolates from honey bee colonies infected with American foulbrood disease in Egypt
The American foulbrood disease is widely distributed all over the world and causes a serious problem for the honeybee industry. Different infected larvae were collected from different apiaries, ground in phosphate saline buffer (PSB) and bacterial isolation was carried out on nutrient agar medium. Different colonies were observed and were characterized biologically. Two bacterial isolates (SH11...
