Flower bud and leaf samples collected from a wide range of native Nort
h American Vaccinium populations were tested for the presence of blueb
erry shoestring virus (BBSSV) using the enzyme-linked immunosorbant as
say. The highest incidence was found in Michigan (14%), although a few
positive samples also were found in Virginia, New Jersey, Maine, Onta
rio, and Quebec. Of seven species tested, only V. corymbosum L. and V.
angustifolium Ait. were infected with BBSSV.
