Six female dogs (four pregnant and two nonpregnant) were inoculated with bluetongue virus (BTV), serotype 11. Pregnant animals and one nonpregnant dog received 5.5-6.3 log10 of cell culture-adapted virus. The other nonpregnant dog received a modified live vaccine contaminated with bluetongue virus. The non-pregnant animals never became clinically ill and(More)
The Virus-Serum-Toxin Act of 1913 (21 US Code 151-159) provides the legal basis for the regulation of veterinary biologicals in the United States; the United States Department of Agriculture's Center for Veterinary Biologicals (CVB) has the regulatory authority for the issue of licences and permits for such products. The law was intended to establish(More)
Scanning tunneling microscopy (STM) images of l-docosanol, 1-docosanethiol, didocosyl disulfide, and 1-chlorooctadecane on graphite are compared. The images of the I-docosanethiol and didocosyl disulfide show bright spots which are attributed to the positions of the S-H and S-S functional groups. The STM images of the l-docosanol and l-chlorooctadecane do(More)
Selected cultures of Moraxella bovis were studied in calves, using chambers fabricated from a semipermeable membrane supported and protected by perforated plastic golf balls. Plain balls, semipermeable membrane-covered balls, and balls that contained bags fabricated from semipermeable membranes were surgically implanted subcutaneously in calves at a site(More)
One of the challenges that has confronted Optimality Theory resides in Phenomena that seem to require reference to an intermediate form that is neither the underlying input nor some actual occurring output. Typically, in rule-based phonology, such phenomeana reflect opaque rule interaction involving counterfeeding or counterbleeding relationships. In order(More)
In vitro assay systems that measure the antigen content of veterinary biologic products use a statistical model for quantification. The most prevalent assay system for measuring veterinary biologics in the United States compares a reference, demonstrated to be protective in the host species, to the serial being tested. An ideal statistical model evaluates(More)
