Porcine epidemic diarrhea virus (PEDV), which emerged in the United States in 2013, has spread throughout North America. Limited availability of PEDV complete genomes worldwide has impeded our understanding of PEDV introduction into the United States. To determine the relationship between the North American strains and global emerging and historic PEDV… (More)
Rotavirus C (RVC) is a major cause of gastroenteritis in swine. Between December 2009 and October 2011, 7520 porcine samples were analyzed from herds in the US and Canada. RVC RNA was detected in 46% of the tested samples. In very young pigs (≤3 days old) and young piglets (4-20 days old), 78% and 65%, respectively, RVC positive samples were negative for… (More)
Astrovirus has been reported to be associated with diarrhea in pigs. The current study was conducted for the detection and molecular characterization of astroviruses in diarrheic pigs submitted to the Veterinary Diagnostic Laboratory, University of Minnesota. Intestinal contents from 269 pigs were examined by reverse transcription polymerase chain reaction… (More)
Numerous, ongoing outbreaks in Brazilian swine herds have been characterized by vesicular lesions in sows and acute losses of neonatal piglets. The complete genome of Seneca Valley virus (SVV) was identified in vesicular fluid and sera of sows, providing evidence of association between SVV and vesicular disease and viraemia in affected animals.
Rotavirus (RV) is an important cause of gastrointestinal disease in animals and humans. In this study, we developed an RT-PCR to detect RV group B (RVB) and characterized the VP7 (G) gene segment detected in porcine samples. One hundred seventy three samples were tested for RV group A (RVA), RVB, and C (RVC) by RT-PCR and examined for RV-like lesion using… (More)
In February 2014, porcine deltacoronavirus (PDCoV) was identified in the United States. We developed a PDCoV real-time reverse transcription PCR that identified PDCoV in 30% of samples tested. Four additional PDCoV genomes from the United States were sequenced; these had ≈99%-100% nt similarity to the other US PDCoV strains.
Porcine epidemic diarrhea virus (PEDV) has been detected sporadically in Italy since the 1990s. We report the phylogenetic relationship of swine enteric coronaviruses collected in Italy during 2007-2014 and identify a drastic shift in PEDV strain variability and a new swine enteric coronavirus generated by recombination of transmissible gastroenteritis… (More)
The highly contagious and deadly porcine epidemic diarrhea virus (PEDV) first appeared in the US in April 2013. Since then the virus has spread rapidly nationwide and to Canada and Mexico causing high mortality among nursing piglets and significant economic losses. Currently there are no efficacious preventive measures or therapeutic tools to control PEDV… (More)
Porcine epidemic diarrhea virus (PEDV) spread rapidly after being diagnosed in the USA in April 2013. In this study we assessed whether PEDV could become airborne and if so, whether the virus was infectious. Air samples were collected both from a room containing experimentally infected pigs and at various distances from the outside of swine farms… (More)
Rotaviruses are important cause of diarrhea in animals, including humans. Currently, rotavirus species A, B, C, E, and H (RVA-RVC, RVE, and RVH) have been identified in pigs. Traditionally, RVA has been considered the primary cause of diarrhea in pigs, and RVB and RVC had been described sporadically in pigs until recently. Qualitative porcine RVA, RVB, and… (More)
