Molecular characterization of viruses found in honeybee (Apis mellifera) colonies infested with Varroa destructor and Nosema cerana in Egypt.

Honey bees (Apis mellifera) have a vital role as pollinators of various crops in the global food supply. Honeybee colonies in Egypt have recently experienced an unexplained rise in annual loss due to a phenomenon known as Colony Collapse Disorder (CCD). In the current study, honey bees were collected from 14 sites from eight governorates in Egypt.
