Six RNA extraction methods, i.e., RNAqueous kit, Micro-to-midi total RNA purification system, NucleoSpin RNA II, GenElute mammalian total RNA kit, RNeasy mini kit, and TRIzol LS reagent, were evaluated on blood and 7 tissues from pig infected with classical swine fever virus (CSFV). Each of the 6 extraction methods yielded sufficient RNA for positive(More)
In February and March 2009, approximately 1,500 backyard pigs of variable age became sick, and approximately 700 of them died or were euthanized in the Lower Artibonite Valley and the Lower Plateau of the Republic of Haiti. The main clinical sign was posterior ataxia followed by paresis and/or paralysis on the second or third day of illness. No gross(More)
Detection of FMDV non-structural protein 3D antibodies has been used as a complementary method for sero-epidemiological studies as an indirect indicator of FMDV infection. In order to develop a sensitive cELISA to detect FMDV antibodies, immune dominant epitopes in FMDV-3D protein were identified by peptide array analysis. Monoclonal antibodies were then(More)
There is limited information about the pathogenesis and epidemiology of foot-and-mouth disease (FMD) in North American bison (Bison bison) or elk (Cervus elaphus nelsoni). In these two experimental infection studies, we compared the susceptibilities of bison and elk to FMD virus (FMDV), respectively, with that of cattle; determined whether intra- and(More)
The stability of transgenic DNA encoding the synthetic cp4 epsps protein in a diet containing Roundup Ready (RR) canola meal was determined in duodenal fluid (DF) batch cultures from sheep. A real-time TaqMan PCR assay was designed to quantify the degradation of cp4 epsps DNA during incubation in DF at pH 5 or 7. The copy number of cp4 epsps DNA in the diet(More)
There is limited information on the pathogenesis and epidemiology of foot-and-mouth disease (FMD) in North American wildlife and none concerning pronghorn ( Antilocapra americana ). In an experimental study of 13 pronghorn and six steers ( Bos taurus ), we compared the susceptibility of pronghorn to FMD virus (FMDV) strain O, with that of cattle ( Bos(More)
Capripoxviruses (CaPVs), consisting of Sheeppox virus (SPV), Goatpox virus (GPV), and Lumpy skin disease virus (LSDV) species, cause economically significant diseases in sheep, goats, and cattle, respectively. Quantitative real-time polymerase chain reaction (qPCR) assays are routinely used for rapid detection of CaPVs in surveillance and outbreak(More)
