Journal ArticleDOI

David L. Suarez,Dennis A. Senne,Jill Banks,Ian H. Brown,Steve Essen,Chang-Won Lee,Ruth J. Manvell,Christian Mathieu-Benson,Valentina Moreno,Janice C. Pedersen,Brundaban Panigrahy,Hernán Rojas,Erica Spackman,Dennis J. Alexander +13 more
TL;DR: Sequence analysis of all eight genes of the LPAI virus and the HPAI viruses showed minor differences between the viruses except at the hemagglutinin (HA) cleavage site, which indicates a virulence shift.
Journal ArticleDOI
Pandemic (H1N1) 2009 in breeding turkeys, Valparaiso, Chile.
Christian Mathieu,Valentina Moreno,Patricio Retamal,Alvaro Gonzalez,Alejandro Rivera,Jorge Fuller,Cecilia Jara,Claudio Lecocq,Miriam Rojas,Alfonso García,Marcela Vasquez,Michel Agredo,Cristian Gutiérrez,Hector Escobar,Rodrigo Fasce,Judith Mora,Julio García,Jorge Fernández,Claudio Ternicier,Patricia Avalos +19 more
TL;DR: The H1N1 2009 virus was detected in breeding turkeys on 2 farms in Valparaiso, Chile and was associated with measurable declines in egg production and shell quality.
Journal ArticleDOI
Avian Influenza in wild birds from Chile, 2007-2009.
Christian Mathieu,Valentina Moreno,Janice C. Pedersen,Julissa Jeria,Michel Agredo,Cristian Gutiérrez,Alfonso García,Marcela Vasquez,Patricia Avalos,Patricio Retamal +9 more
TL;DR: The detection of three avian influenza strains in gulls from Chile between 2007-2009 are reported, which nucleotide sequences showed highest similitudes to viruses detected in wild birds from North America, suggesting a dissemination route for influenza viruses along the coasts of Americas.
Journal ArticleDOI
Epidemiological investigations of the introduction of porcine reproductive and respiratory syndrome virus in Chile, 2013-2015.
Víctor Neira,Barbara Brito,Juan Mena,Juan Mena,Marie R. Culhane,Maria Ignacia Apel,Vanessa Max,Patricio Perez,Valentina Moreno,Christian Mathieu,Magdalena Johow,Catalina Badia,Montserrat Torremorell,Rafael A. Medina,Rafael A. Medina,René Ortega +15 more
TL;DR: The results indicate that the outbreaks in Chile between October 2013 and April 2015 were caused by a PRRSV closely related to viruses present in swine farms in North America, and different from the strain that circulated in the country before 2009.
Journal ArticleDOI
Evaluation of the pathogenicity and transmissibility of a chilean isolate of porcine reproductive and respiratory syndrome virus.
TL;DR: Results indicate that the donor group excreted infectious PRRSV and was able to transmit the infection to susceptible pigs, and the critical shedding period was 7-19 dpi, during which, most likely, transmission took place.
