Evolution of the Sacbrood Virus
The evolution of the Sacbrood virus (SBV) is characterized by the genomic changes that have occurred in SBV since its initial discovery in 1913, which have enabled the virus to continuously infect a wide array of honeybee colonies. SBV is single stranded RNA virus (genus: Iflavirus) that most commonly infects honeybee larvae, and is known to wipe out entire honeybee colonies quickly.
