Allen Szalanski presents: Molecular Diagnostics of Nosema ceranae and apis from Honey Bees in New York. American Bee Research Conference. Orlando, Fl. January 15th, 2010.
31. Szalanski, A., J. Whitaker & P. Cappy – MOLECULAR DIAGNOSTICS OF NOSEMA CERANAE AND N. APIS FROM HONEY BEES IN NEW YORK - Molecular diagnostics of the invasive honey bee pathogens, Nosema ceranae and N. apis, were conducted on honey bees from New York. A total of 1200 honey bee samples were collected by NYSDAM bee inspectors, of which, 528 (44%), from 49 counties had a positive Nosema spore count. Spore counts were the highest in the Spring and decreased into the Fall. PCR genetic analysis on 371 spore-positive samples revealed that 96% were N. ceranae, 3% had both N. ceranae and N. apis, and 1% had N. apis. Nosema ceranae was more common in commercial operations relative to sideliner and hobbyist beekeepers. A preliminary molecular phylogenetic analysis of N. ceranae from New York revealed that it is identical to N. ceranae from Nebraska, South Dakota, Wisconsin, Europe and Australia.
