Journal ArticleDOI
Identification of a Divergent Lineage Porcine Pestivirus in Nursing Piglets with Congenital Tremors and Reproduction of Disease following Experimental Inoculation
Bailey Arruda,P. H. Arruda,Drew R. Magstadt,Kent Schwartz,Tyler M. Dohlman,Jennifer A. Schleining,Abby R. Patterson,Callie Ann Visek,Joseph Gilbert Victoria +8 more
TL;DR: This is the first reported reproduction of congenital tremors following experimental inoculation with a divergent lineage porcine pestivirus and studies investigating disease mechanism, epidemiology, and diagnostic assay development are needed to better understand the pathophysiology of congenitals tremors due to this pestiv virus.
Journal ArticleDOI
Comparison of sesion severity, distribution, and colonic mucin expression in pigs with acute swine dysentery following oral inoculation with "Brachyspira hampsonii" or Brachyspira hyodysenteriae.
B. L. Wilberts,P. H. Arruda,Joann M. Kinyon,Darin M. Madson,Timothy S. Frana,Eric R. Burrough +5 more
TL;DR: This study reveals significant alterations in colonic mucin expression in pigs with acute swine dysentery and further reveals that these and other microscopic changes are similar following infection with “B. hampsonii” clade II or B. hyodysenteriae.
Journal ArticleDOI
Detection of atypical porcine pestivirus in Brazil in the central nervous system of suckling piglets with congenital tremor.
Igor Renan Honorato Gatto,Karen M. Harmon,Laura K. Bradner,Pedro Barbosa da Silva,Daniel Linhares,P. H. Arruda,L. G. de Oliveira,Bailey Arruda +7 more
TL;DR: Phylogenetic analysis revealed that Brazilian sequences of the NS3 formed an independent cluster and had the highest sequence identity with a sequence from the United States, the first identification of APPV infection in piglets with CT in South America.
Journal ArticleDOI
Detection of atypical porcine pestivirus in semen from commercial boar studs in the United States
Igor Renan Honorato Gatto,P. H. Arruda,Callie Ann Visek,Joseph Gilbert Victoria,Abby R. Patterson,Adam C. Krull,Kent Schwartz,L. G. de Oliveira,Bailey Arruda +8 more
TL;DR: This is the first report of detection of APPV in semen from commercial boar studs and studies investigating the role of semen in the transmission ofAPPV and production of CT are needed.
Journal ArticleDOI
Cessation of clinical disease and spirochete shedding after tiamulin treatment in pigs experimentally infected with "Brachyspira hampsonii"
TL;DR: The effectiveness of tiamulin in resolving clinical disease, eliminating viable spirochete shedding, and reducing neutrophilic colitis following infection with either "B. hampsonii" or B. hyodysenteriae was evaluated.
