Rapid bilateral intraocular cocktail sampling method for West Nile virus detection in dead corvids. (56/117)

Corvids can be a sensitive indicator for West Nile virus (WNV) prevalence and are a component of many WNV surveillance programs. An improved sampling procedure using a bilateral intraocular cocktail (BIC) was developed for testing corvid carcasses for WNV. This new procedure was substantially faster than harvesting internal organs, required less specialized equipment and training, and yielded excellent diagnostic sensitivity.  (+info)
