Replication-deficient adenoviral (rAd5) vaccines containing codon-optimized E1, E2, E4, and E7 genes of canine oral papillomavirus (COPV) were tested singly or in combination to determine which vaccines could protect against mucosal challenge with COPV. In three studies, groups of 4-6 beagle dogs were immunized subcutaneously (s.c.) with 10(11) rAd5 at 8-10(More)
The effects of aqueous extracts of Ilex paraguariensis leaves (AEIp) were studied. Mesenteric arterial bed (MAB), precontracted by methoxamine with or without intact endothelium, was mounted on a tissue bath and exposed to plant extracts (bolus). The bolus injections of AEIp (300-1050 microg) significantly inhibited, in a concentration-dependent manner, the(More)
Effects of various doses of bovine somatotropin (bST) on plasma concentrations of nonesterified fatty acids (NEFA) were studied in a 14-d Latin square with six Holstein heifers. Animals were given daily injections of excipient or bST at 12:00 p.m. and fed twice daily at 7:00 a.m. and 7:00 p.m. On Day 14, plasma NEFA remained low through the day except(More)
Live, cold-adapted, temperature-sensitive (ca/ts) Russian influenza A vaccines are prepared in eggs by a 6:2 gene reassortment of the ca/ts donor strain A/Leningrad/134/17/57 (H2N2) (Len/17) with a current wild-type (wt) influenza A strain contributing hemagglutinin (HA) and neuraminidase (NA) genes. However, egg-derived reassortant vaccines are potentially(More)
The effects of infections of Trichinella spiralis on 10 specific-pathogen-free Beagles were examined. Eight puppies received either 100, 500, 1,000, or 5,000 larvae, and 2 adult dogs received 1,000 larvae. Blood was drawn every 4 days, beginning 5 days before infection, for the determination of relative eosinophil numbers. Creatine kinase levels were(More)
