Disease pathogenesis was characterized by microscopic lesions in the nasal turbinates and lungs of all ferrets; however, Sw30 infection was associated with severe bronchointerstitial pneumonia. The results demonstrate that although CA09 is highly transmissible in the human population and replicates well in the ferret model, it causes modest disease compared to other H1N1 viruses, particularly Sw30 infection.\n          <\/jats:p>","DOI":"10.1128\/jvi.00512-11","type":"journal-article","created":{"date-parts":[[2011,5,19]],"date-time":"2011-05-19T02:24:46Z","timestamp":1305771886000},"page":"7572-7581","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["Comparative Pathology in Ferrets Infected with H1N1 Influenza A Viruses Isolated from Different Hosts"],"prefix":"10.1128","volume":"85","author":[{"given":"Jennifer Humberd","family":"Smith","sequence":"first","affiliation":[{"name":"Department of Infectious Diseases, University of Georgia, College of Veterinary Medicine, Athens, Georgia 30602"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamas","family":"Nagy","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, University of Georgia, College of Veterinary Medicine, Athens, Georgia 30602"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Driskell","sequence":"additional","affiliation":[{"name":"Department of Veterinary Pathology, University of Georgia, College of Veterinary Medicine, Athens, Georgia 30602"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Brooks","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, University of Georgia, College of Veterinary Medicine, Athens, Georgia 30602"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
