*Antibodies were detected by agar gel immunodiffusion, and final subtyping was determined at the National Veterinary Services Laboratories (Ames, IA, USA). N, negative; WP, weakly positive; SP, strongly positive; NS, not sampled; P, positive.
†H, hemagglutinin; N, neuraminidase.
‡Uninoculated raccoons housed in adjacent cages to infected raccoons.
§These raccoons had preexisting antibodies (262:H10N7, 1:10; 263:H4N6 1:40).
¶Raccoon humanely killed 8 days postinoculation.
