Detection and Isolation of Airborne Influenza A H3N2 Virus Using a Sioutas Personal Cascade Impactor Sampler

<table>Early formation of influenza virus-specific CPE in cells inoculated with material collected by a PCIS at air sampling site 3. (a) Noninfected ATCC MDCK cells (negative control), 3 days postseed. (b) ATCC MDCK cells inoculated with material scraped off the PCIS after-filter. (c) Noninfected MDCK-SIAT2,6-UF cells, (negative control), 3 days postseed. (d) MDCK-SIAT2,6-UF cells inoculated with material scraped off the PCIS after-filter.</table>
