Hello All, >Are you refereing to Ebola or E. coli? Ebola (sorry for the typo) >The former is a non-spore forming virus Not according to everything I have read. 573,000 hits for virus spores on google. Perhaps the term *virus spores* paints all virus with a broad brush. DWV spores is what beekeeping researchers have said. Based on their input we are running large and expensive tests to determine it a swarm (package) hived on prior PMS comb is more susceptible than a swarm hived on new comb. Perhaps the word " virus spore" is slang for whatever agent is present on the comb . I am not a researcher so will gladly admit to being wrong if indeed a virus does not use spores.
