title: Survival of duck plague virus in water from Lake Andes National Wildlife Refuge, South Dakota.
abstract: An isolant of duck plague herpesvirus from the Lake Andes Refuge outbreak was seeded in raw and filter-decontaminated water from two locations on the refuge, held at 4 C, and assayed for infectivity intermittently over a period of 2 mo. From an initial level of about 10(5) PFU per ml, infectivity in the filtered samples uniformly dropped to about 10(4) PFU per ml. Infectivity in the raw samples declined much more rapidly; infectious virus remaining at the end of 2 mo (ca. 10(1) PFU per ml) was only about 0.01% of that originally seeded.
