Urban Coatis (Nasua nasua) Exposure to Alphainfluenzavirus influenzae

We detected neutralizing antibodies, viral RNA, and sialic acid receptors for Alphainfluenzavirus influenzae in urban coatis (Nasua nasua) in Brazil, suggesting exposure and susceptibility. We used hemagglutination inhibition, reverse transcription quantitative PCR, and histochemistry for detection. Increased epidemiologic wildlife surveillance would improve influenza A emergency event response.
