Cellular alterations in midgut cells of honey bee workers (Apis...

Beside many beneficial applications in industry, agriculture and medicine, nanoparticles (NPs) released into the environment might cause adverse effects. In the present study, effects of exposure to sublethal concentrations of PbO and CdO NPs, either separately or in combination on honey bee (A. mellifera) workers were assessed. Honey bee workers were fed sugar syrup contained…

Reference: Haddad, N., Horth, L., Al-Shagour, B., Adjlane, N., & Loucif-Ayad, W. (2018). Next-generation sequence data demonstrate several pathogenic bee viruses in Middle East and African honey bee subspecies (Apis mellifera syriaca, Apis mellifera intermissa) as well as their cohabiting pathogenic mites (Varroa destructor). Virus genes, 1-12. RNA viruses are associated with honey bee (Apis…

Characterization of Apis mellifera honey from different botanical and geographical...

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...

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…
