The Developmental Process For Adenoviral Vectored Canine Influenza Vaccines, Nicholas Jeanjaquet
The Developmental Process For Adenoviral Vectored Canine Influenza Vaccines, Nicholas Jeanjaquet
School of Biological Sciences: Dissertations, Theses, and Student Research
Canine Influenza Virus (CIV) is a recently emerged branch of Influenza A virus that is highly infectious in dogs. The first strain was isolated in 2003, and it has quickly become endemic in areas with dense dog populations, most notably in Asia. The proximity of dogs to humans, along with their potential to serve as mixing vessels for reassortment, raises concern for possible zoonotic transmission and a potential human pandemic. Available vaccines are not frequently updated and struggle to prevent the spread of currently circulating strains. This highlights the need for a new and more effective vaccine. We outline the …
Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty
Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty
SURE Journal: Science Undergraduate Research Experience Journal
Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …

Chronic wasting disease (CWD) is an infectious, neurodegenerative disease of deer (white-tailed and mule), elk, moose, sika deer and muntjac caused by a misfolded version of a normally occurring protein. The notion that CWD could be spread indirectly via the environment has been documented and accepted in the scientific community for quite some time. Deer and elk consume soil, inhale dust and lick objects that have infectious material on them, resulting in chronic, low dose exposure. Surface contamination of plants with urine or feces is likely an additional source of exposure via ingestion and has been modeled in the laboratory …

Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating
Cross-Sectional Analysis Of Salivary Cortisol And Cyathostome Infestation In Horses, Danielle L. Keating
Undergraduate Honors Thesis Projects
With an increase in anthelmintic resistance and decreased efficacy of many commercial dewormers, understanding factors that contribute to parasite infestations in horses is integral to their management. The goal of this study was to look at the potential relationship between parasites and stress response by evaluating salivary cortisol levels and cyathostome egg shedding levels. Using a sample size of n = 200 horses from the state of Ohio, fecal and saliva samples were collected from each horse. Fecal egg counts were performed for each horse with a modified Stoll method, and saliva samples were tested with an enzyme-linked immunosorbent assay …

USDA Wildlife Services: Staff Publications
White-tailed deer (Odocoileus virginianus) serve as a reservoir for bovine tuberculosis, caused by Mycobacterium bovis, and can be a source of infection in cattle. Vaccination with M. bovis Bacille Calmette Guerin (BCG) is being considered for management of bovine tuberculosis in deer. Presently, no method exists to non-invasively monitor the presence of bovine tuberculosis in deer. In this study, volatile organic compound profiles of BCG-vaccinated and non-vaccinated deer, before and after experimental challenge with M. bovis strain 95–1315, were generated using solid phase microextraction fiber head-space sampling over suspended fecal pellets with analysis by gas chromatography/mass spectrometry. …

Purpose: Gastrointestinal nematodes (GIN) hinder the sustainable production of small ruminants on pasture and parasite resistance to chemical dewormers is becoming a growing concern. Condensed tannin containing legume forages are being tested to evaluate their anti-parasitic properties and potential contribution to an overall parasite control program for small ruminants such as sheep and goats. One of the most pathogenic GIN of small ruminants is Haemonchus contortus. The final step to full infectivity of H. contortus third stage larvae (L3) is exsheathment in the rumen. The objective of this study was to establish an in-vivo exsheathment assay in fistulated sheep …

Glucose Significantly Enhances Enterotoxigenic Escherichia Coli Adherence To Intestinal Epithelial Cells Through Its Effects On Heat-Labile Enterotoxin Production, Prageeth Wijemanne, Rodney A. Moxley
School of Veterinary and Biomedical Sciences: Faculty Publications
The present study tested whether exposure of enterotoxigenic Escherichia coli (ETEC) to glucose at different concentrations in the media results in increased bacterial adherence to host cells through increased heat-labile enterotoxin (LT) production, thereby suggesting the effects are physiological. Porcine-origin ETEC strains grown in Casamino acid yeast extract medium containing different concentrations of glucose were washed and inoculated onto IPEC-J2 porcine intestinal epithelial cells to test for effects on adherence and host cell cAMP concentrations. Consistent with previous studies, all LT+ strains had higher ETEC adherence to IPEC-J2 cells than did LT2 strains. Adherence of the LT2 but not the …

Tales From Dead Lambs : Results Of A Survey Of Lambing Losses, Stanley M. Dennis
Journal of the Department of Agriculture, Western Australia, Series 4
During the past year the Animal Health Laboratory has been conducting a preliminary survey into the infectious causes of abortion in sheep and perinatal lamb mortalities. This work was prompted by:
* The diagnosis of vibrionic abortion for the first time in Western Australia in 1961, and
* The estimate that 30 per cent, of all ewes mated in Australia each year may fail to produce a viable lamb that survives to marking time.
This enormous lamb wastage is due to a variety of causes and the role of infectious agents has yet to be evaluated.

Diseases Of Goats, J Shilkin
Diseases Of Goats, J Shilkin
Journal of the Department of Agriculture, Western Australia, Series 4
MANY of the diseases of goats are common to sheep and cattle, and, as in these species, correct feeding, hygiene and general care and management will assist in the avoidance of serious ailments.
In this article an attempt will be made to advise goat-owners on the diagnosis of the more common ailments, and suggestions as to treatment will be offered where possible.
It should be appreciated however that where veterinary assistance is obtainable it is preferable to first-aid treatment. A qualified veterinarian has access to newer and more efficient methods of treatment than are available to the layman.
