Characterization of Apis mellifera honey from different botanical and geographical origins in Egypt

ArticlesLeave a comment

Seven bee honey types identified botanically in terms of their floral origin (Clover, Cedrus, Citrus, Banana, Cotton, Brazilian pepper, and Sun flower), and their geographical regions during 2016 – 2017 have been characterized in comparison with artificial honey. Characterization of honeys was based on their physicochemical properties, antimicrobial activity, heavy metal contents and multi-pesticides residues…

Virulence of M. plutonius and secondary invaders associated with European foulbrood disease

ArticlesLeave a comment

European foulbrood is a globally distributed brood disease affecting honey bees. It may lead to lethal infections of larvae and, in severe cases, even to colony collapse. Lately, a profound genetic and phenotypic diversity was documented for the causative agent Melissococcus plutonius. However, experimental work on the impact of diverse M. plutonius strains on hosts with…

The Fate of Major Royal Jelly Proteins during Proteolytic Digestion in the Human Gastrointestinal…

ArticlesLeave a comment

Royal jelly (RJ) is a beehive product with a complex composition, major royal jelly proteins (MRJPs) being the most abundant proteins. Cell culture and animal studies suggest various biological activities for the full-length/native MRJPs. In the field of apitherapy, it is assumed that MRJPs can positively affect human health. However, whenever RJ is administered orally,…

Perfect Match: Simultaneous Strawberry Pollination & Bio-Sampling of the Plant Pathogenic Bacterium

ArticlesLeave a comment

Abstract In this study we show that honey bee colonies placed in a greenhouse for pollination of strawberry can simultaneously be used to indicate the presence of the plant pathogenic bacterium Erwinia pyrifoliae. This was demonstrated by using two methods of qualitative sacrificial and non-sacrificial bio sampling of the honey bee colony. A novel method…
