Evaluation Of Broad Anti-Herpesviral Activity With Α-Hydroxytropolones, Shannon David Dehghanpir Jan 2017

Evaluation Of Broad Anti-Herpesviral Activity With Α-Hydroxytropolones, Shannon David Dehghanpir

LSU Master's Theses

Herpesviruses are ubiquitous in animals and cause economic losses concomitant with many diseases, including upper respiratory disease, keratitis, abortion, neonatal death, and neurologic disease. The majority of the domestic animal herpesviruses are within the subfamily Alphaherpesvirinae, along with the prototypical human herpes simplex virus 1 (HSV-1). Suppression of HSV-1 replication has been reported with α-hydroxytropolones (αHTs), which are aromatic ring compounds that have broad bioactivity due to potent chelating activity. It is postulated that αHTs inhibit enzymes within the nucleotidyltransferase superfamily (NTS), similarly structured enzymes that require divalent cations for nucleic acid cleavage activity. One potential herpesviral target includes the …

The Effect Of Feed Form On Diet Digestibility And Cecal Parameters In Rabbits, Isabella Corsato Alvarenga, Charles Gregory Aldrich, Micah Kohles

School of Veterinary and Biomedical Sciences: Faculty Publications

Fifteen New Zealand rabbits were randomly assigned to one of 3 dietary treatment groups of 5 animals each and fed pelleted, extruded, or muesli diets in a completely randomized design experiment. Rabbits were placed in individual cages with ad libitum access to water and food for 45 days acclimation followed by 30 days experimental period. Feed intake of rabbits fed pelleted and extruded diets was greater (p < 0.05) than rabbits fed the muesli diet (125.6 and 130.4 vs. 91.9 g/d), but weight change and feed efficiency were not affected by treatment. Diet digestibility among the treatments was inconsistent when comparing results obtained from total fecal collection and AIA (please define) as an internal marker. Rabbits fed extruded and pelleted diets had lower (p < 0.05) cecal pH (6.42 and 6.38 vs. 7.02, respectively), and higher (p < 0.05) production of SCFA (18.5 and 19.0 vs. 11.7 mM, respectively) than those fed muesli. The fermentation products from rabbits fed pelleted and extruded diets had a greater proportion of butyrate and less propionate than rabbits fed muesli. The results of this study indicate that the basal dietary composition had a greater impact on diet utilization and cecal fermentation than food form.

School of Veterinary and Biomedical Sciences: Faculty Publications

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of Johne’s disease in ruminants causing chronic diarrhea, malnutrition, and muscular wasting. Neonates and young animals are infected primarily by the fecal–oral route. MAP attaches to, translocates via the intestinal mucosa, and is phagocytosed by macrophages. The ensuing host cellular immune response leads to granulomatous enteritis characterized by a thick and corrugated intestinal wall. We review various tissue culture systems, ileal loops, and mice, goats, and cattle used to study MAP pathogenesis. MAP can be detected in clinical samples by microscopy, culturing, PCR, and an enzyme-linked immunosorbent assay. There are commercial …
