Interactions between co-circulating respiratory viruses are recognized for their impact on 17 viral transmission and clinical outcomes. However, the consequences of these virus-virus 18 interactions at the cellular level are unclear. We coinfected human lung cells with influenza A 19 virus (IAV) and respiratory syncytial virus (RSV). Super-resolution microscopy combined 20 with live-cell imaging and scanning electron microscopy identified extracellular and 21 membrane-associated filamentous structures, likely composed of elements of both IAV and 22 RSV virions. Cryo-electron tomography confirmed the presence of chimeric virus particles 23 exhibiting glycoproteins and ribonucleoproteins of both parental viruses. Functional assays 24 revealed chimeric particles facilitate IAV infection in cells depleted of IAV receptors, 25 demonstrating expanded tropism. Our observations define a previously unknown interaction 26 that is likely to affect virus pathogenesis and have profound implications for infection 27 biology. 28
