Table 1.

Number of positive nasal and saliva swabs out of those tested for the matrix (M) gene of influenza A viruses and for the specific H1pdm gene. All samples were analyzed for the M gene whereas only M gene-positive samples were also tested for H1pdm.

*Three piglets were positive at both swab types. **Saliva swabs did not provide enough fluid for analysis. §half of the piglets were asymptomatic. #Samples were analyzed only in pools; 16 pools correspond to 120 individual swabs, 60 of which originated from asymptomatic piglets.
