Although further investigation and refinement of the sampling method is needed, results indicate that snout wipes will facilitate convenient and undisruptive IAV surveillance in pigs at agricultural fairs.

The reduction in infectious agents in the air by the EPI technology could potentially decrease the microbial exposure for pigs.

We demonstrate the asymptomatic circulation of IAV-S in the Vietnamese pig population.

The data present bronchial scraping as an equally effective or even better alternative to bronchoalveolar lavage fluid for detecting main porcine respiratory disease complex agents.

The differences in shedding pattern and cytokine and immune responses are important for studies of disease pathogenesis and assessment of vaccine protective efficacy.

Findings suggest that concentrated swine feeding operations amplified transmission of influenza during years in which H1N1 was circulating.

Our data shows that natural infection by contact induces remarkably high innate and adaptive immune response, although the animals were exposed to a very low virus dose.

Serum antibodies against NP provide an ideal universal diagnostic screening target and could provide a cost-effective approach for the detection and surveillance of IAV infections in swine populations.

Results demonstrated remarkable IAV diversity, and the complex, rapid and dynamic evolution of IAV during infection of vaccinated pigs that can only be appreciated with repeated sampling of individual animals and deep sequence analysis.

Our data indicates that although high titers of vaccine-derived MDA reduced homologous virus infection, transmission, and disease, MDA alone was sufficient to induce vaccine associated enhanced respiratory disease upon heterologous infection.

Our results indicate that during outbreaks of IAV in swine, aerosols and surfaces in barns contain significant levels of IAV potentially representing an exposure hazard to both swine and people.

Taken together, the results confirm the widespread presence of PPIV1 in the United States swine herd.

Our data indicated that H3N8 IAV from wild aquatic birds have the potential to cross the species barrier and establish successful infections in pigs that might spread unnoticed using HAI as diagnostic tool.

Overall, our findings indicate that at least 12 genetically distinct HA lineages circulate in Latin American swine herds, only two of which have been found in North American swine herds.

Our results suggest that infection with IAV or PRRSV in the pre-weaning period is associated with an increase in post-weaning mortality.

Based on these findings, we recommend that IAV control strategies be aimed at preventing infection before gilts are introduced into the farm, and in pigs prior to weaning.
