Journal ArticleDOI
Molecular characterization and typing of chicken and turkey astroviruses circulating in the United States: implications for diagnostics.
TL;DR: A revision of the present taxonomic classification for avian astroviruses within the genus Avastrovirus is warranted after no correlation was observed between the detection of a particular astrovirus and the presence of enteric disease or poor performance.
Journal ArticleDOI
Sequence Analysis of Recent H7 Avian Influenza Viruses Associated with Three Different Outbreaks in Commercial Poultry in the United States
TL;DR: Phylogenetic analysis of the hemagglutinin (HA) and neuraminidase (NA) genes demonstrates that the isolates from commercial poultry were closely related to the viruses circulating in the LBMs.
Journal ArticleDOI
The pathogenesis of low pathogenicity H7 avian influenza viruses in chickens, ducks and turkeys
Erica Spackman,Jack Gelb,Lauren A. Preskenis,Brian S. Ladman,C. R. Pope,Mary J. Pantin-Jackwood,Enid T. McKinley +6 more
TL;DR: Turkeys may be more susceptible to clinical disease from the H7 LPAI viruses included in this study than either chickens or ducks, however the severity of disease and degree of virus shed was not clearly correlated with any isolate or group of isolate, but relied on specific species and isolate combinations.
Journal ArticleDOI
Development and validation of a real-time Taqman PCR assay for the detection and quantitation of infectious laryngotracheitis virus in poultry.
Scott A. Callison,Sylva M. Riblet,Ivomar Oldoni,S. Sun,Guillermo Zavala,Susan M. Williams,R. S. Resurreccion,Erica Spackman,Maricarmen García +8 more
TL;DR: The ReTi ILTV assay was highly specific, sensitive, reproducible, and capable of reliably quantifying viral nucleic acid directly from clinical samples.
Journal ArticleDOI
Pathogenicity and Transmission of H5 and H7 Highly Pathogenic Avian Influenza Viruses in Mallards
Mary J. Pantin-Jackwood,Mar Costa-Hurtado,Eric Shepherd,Eric DeJesus,Diane Smith,Erica Spackman,Darrell R. Kapczynski,David L. Suarez,David E. Stallknecht,David E. Swayne +9 more
TL;DR: Surprisingly, most HPAI viruses examined in this study replicated well and transmitted among mallards; however, the three Gs/GD lineage H5 HPAi viruses replicated to higher titers, which could explain the transmission of these viruses in susceptible wild duck populations.
