Co-inoculating young adult honey bees with deformed wing virus and sacbrood virus synergistically increases DWV virulence and conditionally promotes SBV replication, linked to higher mortality.
- Why it matters: Co-infections are common in colonies but have rarely been studied in adult bees, leaving uncertainty about how DWV and SBV interact to shape viral dynamics and immune responses.
- What they did: Young adult honey bees were co-inoculated by injecting DWV (vectored transmission by Varroa) and feeding SBV (oral transmission), then reintroduced to colonies; survival, behavior, viral loads, and eight antiviral immune genes were repeatedly quantified.
- The result: Immune responses in adult bees depended on DWV genotype, relative viral abundance, and pre-existing natural infections before DWV injection, and SBV may contribute to DWV replication in specific contexts.
