The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon

Experimentation Collection

Newby and Stevens’ (2008) paper ‘‘The effects of the acetic acid ‘pain’ test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss)’’ examines the effects of a noxious stimulus on the behaviour of trout in an attempt to replicate research conducted in my laboratory (Sneddon, 2003a; Sneddon, 2007; Sneddon et al., 2003a,b; Reilly et al., 2008). However, the authors used a different protocol to the one already published and I would like to respond to some of their points of discussion to provide scientific explanations for their results using data from my laboratory. The authors show that swimming …

Stocker And Backgrounding Self Assessment Jan 2009

Stocker And Backgrounding Self Assessment

Nebraska Beef Quality Assurance Program

Cattlemen in stocker operations have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the well-being of stocker cattle, individual animal health and herd productivity. Stocker cattle operations are located in many diverse environments and geographic locations in the United States. A universal set of production practices can not be recommended for all stocker cattle producers in light of the divergent climate and geographic variations of the stocker and backgrounding segment. Personal experience, training and professional judgment can serve as a valuable resource for …

Prevalence Of Intestinal Parasite Infection In Symptomatic And Asymptomatic Dogs In Southwestern West Virginia: The Potential Impact On Human Health, Tashina Marie Savilla Jan 2009

Prevalence Of Intestinal Parasite Infection In Symptomatic And Asymptomatic Dogs In Southwestern West Virginia: The Potential Impact On Human Health, Tashina Marie Savilla

Theses, Dissertations and Capstones

Most dog owners are unaware of asymptomatic infection and of the possibility of contracting zoonotic parasites from their dogs. We hypothesized that parasite infection is: associated with one or more symptoms; independent of gender and age; and independent of anthelmintic usage. Stool samples were collected from 231 dogs in Kanawha County, West Virginia, and were examined by simple fecal flotation. Parasitic prevalence was found to be 23% for Ancylostoma caninum, 8% for Trichuris vulpis, 7% for Toxocara canis, 4% for Isospora species, and 32.5% overall. There was no significant relationship between infection and gender, nor between infection and symptom for …

Group Feeding For The Lactating Cow, Anthony Joseph Martin Jan 2009

Group Feeding For The Lactating Cow, Anthony Joseph Martin

Dairy Science

Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …

Risk Factors For Human Infection With Puumala Virus, Southwestern Germany, Anne Caroline Schwarz, Ulrich Ranft, Isolde Piechotowski, James E. Childs, Stefan O. Brockmann Jan 2009

Risk Factors For Human Infection With Puumala Virus, Southwestern Germany, Anne Caroline Schwarz, Ulrich Ranft, Isolde Piechotowski, James E. Childs, Stefan O. Brockmann

Zoonotics and Wildlife Disease: Publications

Puumala virus, which causes nephropathia epidemica (NE), is the most prevalent hantavirus in Germany; bank voles serve as the main reservoir. During 2001–2007, most NE cases reported from Germany occurred in the southwestern state of Baden-Württemberg. We investigated the influence of bank vole habitats (beech forest, seed plants), vole food supply (beechnut mast), climate factors (winter and spring temperatures), and human population density on spatial and temporal occurrence of NE cases in Baden- Württemberg. Using Poisson-regression analyses, we found that all these factors influenced disease incidence. Furthermore, an independent trend of increasing incidence predicted that incidence will nearly double each …

Avian Host-Selection By Culex Pipiens In Experimental Trials, Jennifer E. Simpson, Corrine M. Folsom-O’Keefe, James E. Childs, Leah E. Simons, Theodore G. Andreadis, Maria A. Diuk-Wasser

Zoonotics and Wildlife Disease: Publications

Evidence from field studies suggests that Culex pipiens, the primary mosquito vector of West Nile virus (WNV) in the northeastern and north central United States, feeds preferentially on American robins (Turdus migratorius). To determine the contribution of innate preferences to observed preference patterns in the field, we conducted host preference trials with a known number of adult female C. pipiens in outdoor cages comparing the relative attractiveness of American robins with two common sympatric bird species, European starling, Sternus vulgaris and house sparrow, Passer domesticus. Host seeking C. pipiens were three times more likely to enter robin-baited …

Williams, Richard Race, Bruce Chesebro

Zoonotics and Wildlife Disease: Publications

Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy, or prion disease, that affects deer, elk, and moose. Human susceptibility to CWD remains unproven despite likely exposure to CWD-infected cervids. We used 2 nonhuman primate species, cynomolgus macaques and squirrel monkeys, as human models for CWD susceptibility. CWD was inoculated into these 2 species by intracerebral and oral routes. After intracerebral inoculation of squirrel monkeys, 7 of 8 CWD isolates induced a clinical wasting syndrome within 33–53 months. The monkeys’ brains showed spongiform encephalopathy and proteaseresistant prion protein (PrPres) diagnostic of prion disease. After oral exposure, 2 squirrel monkeys had …

Zoonotics and Wildlife Disease: Publications

Since the discovery of the Marburg and Ebola species of filovirus, seemingly random, sporadic fatal outbreaks of disease in humans and nonhuman primates have given impetus to identification of host tropisms and potential reservoirs. Domestic swine in the Philippines, experiencing unusually severe outbreaks of porcine reproductive and respiratory disease syndrome, have now been discovered to host Reston ebolavirus (REBOV). Although REBOV is the only member of Filoviridae that has not been associated with disease in humans, its emergence in the human food chain is of concern. REBOV isolates were found to be more divergent from each other than from the …

Light-Induced Fos Expression In Intrinsically Photosensitive Retinal Ganglion Cells In Melanopsin Knockout (Opn4-/-) Mice, Gary E. Pickard, Scott B. Baver, Malcolm D. Ogilvie, Patricia J. Sollars Jan 2009

Light-Induced Fos Expression In Intrinsically Photosensitive Retinal Ganglion Cells In Melanopsin Knockout (Opn4-/-) Mice, Gary E. Pickard, Scott B. Baver, Malcolm D. Ogilvie, Patricia J. Sollars

School of Veterinary and Biomedical Sciences: Faculty Publications

Retinal ganglion cells that express the photopigment melanopsin are intrinsically photosensitive (ipRGCs) and exhibit robust synaptically driven ON-responses to light, yet they will continue to depolarize in response to light when all synaptic input from rod and cone photoreceptors is removed. The light-evoked increase in firing of classical ganglion cells is determined by synaptic input from ON-bipolar cells in the proximal sublamina of the inner plexiform layer. OFF-bipolar cells synapse with ganglion cell dendrites in the distal sublamina of the inner plexiform layer. Of the several types of ipRGC that have been described, M1 ipRGCs send dendrites exclusively into the …

Ovine Progressive Pneumonia Provirus Levels Are Unaffected By The Prion 171r Allele In An Idaho Sheep Flock, Robert D. Harrington, Lynn M. Herrmann-Hoesing, Stephen N. White, Katherine I. O'Rourke, Donald P. Knowles Jan 2009

Ovine Progressive Pneumonia Provirus Levels Are Unaffected By The Prion 171r Allele In An Idaho Sheep Flock, Robert D. Harrington, Lynn M. Herrmann-Hoesing, Stephen N. White, Katherine I. O'Rourke, Donald P. Knowles

Zoonotics and Wildlife Disease: Publications

Selective breeding of sheep for arginine (R) at prion gene (PRNP) codon 171 confers resistance to classical scrapie. However, other effects of 171R selection are uncertain. Ovine progressive pneumonia/Maedi-Visna virus (OPPV) may infect up to 66% of a flock thus any affect of 171R selection on OPPV susceptibility or disease progression could have major impact on the sheep industry. Hypotheses that the PRNP 171R allele is 1) associated with the presence of OPPV provirus and 2) associated with higher provirus levels were tested in an Idaho ewe flock. OPPV provirus was found in 226 of 358 …

Validation Of Use Of Rectoanal Mucosa-Associated Lymphoid Tissue For Immunohistochemical Diagnosis Of Chronic Wasting Disease In White-Tailed Deer (Odocoileus Virginianus), Delwyn Keane, Daniel Barr, Rebecca Osborn, Julie Langenberg, Katherine I. O'Rourke, David Schneider, Phillip Bochsler

Zoonotics and Wildlife Disease: Publications

The examination of rectoanal mucosa-associated lymphoid tissue (RAMALT) biopsy specimens for the diagnosis of transmissible spongiform encephalopathies has been described in sheep, elk, and small numbers of mule and white-tailed deer. Previous sample numbers have been too small to validate examination of this type of tissue as a viable antemortem diagnostic test. In this study, we examined RAMALT collected postmortem from 76 white-tailed deer removed from a farm in Wisconsin known to be affected by chronic wasting disease (CWD) and from 210 free-ranging white-tailed deer harvested from an area in Wisconsin where the overall prevalence of CWD among the deer …

Vaccination With Mycobacterium Bovis Bcg Strains Danish And Pasteur In White-Tailed Deer (Odocoileus Virginianus) Experimentally Challenged With Mycobacterium Bovis, M. V. Palmer, T. C. Thacker, W. R. Waters

Michigan Bovine Tuberculosis Bibliography and Database

Wildlife reservoirs of Mycobacterium bovis represent serious obstacles to the eradication of tuberculosis in domestic livestock and the cause for many faltering bovine tuberculosis eradication programs. One approach in dealing with wildlife reservoirs of disease is to interrupt inter-species and intraspecies transmission through vaccination of deer or cattle. To evaluate the efficacy of BCG vaccination in white-tailed deer, 35 deer were assigned to one of three groups; one s.c. dose of 107 CFU of M. bovis BCG Pasteur (n = 12); 1 s.c. dose of 107 CFU of M. bovis BCG Danish (n = 11); or unvaccinated deer …

The Effects Of Dietary Conjugated Linoleic Acid (Cla) On Fatty Acid Composition And Key Enzymes Of Fatty Acid Oxidation In Liver And Muscle Of Geese, Xuhui Zhang, Baowei Wang, Fangyu Long, Lei Wang, Zhigang Yang Jan 2009

The Effects Of Dietary Conjugated Linoleic Acid (Cla) On Fatty Acid Composition And Key Enzymes Of Fatty Acid Oxidation In Liver And Muscle Of Geese, Xuhui Zhang, Baowei Wang, Fangyu Long, Lei Wang, Zhigang Yang

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to determine the influence of conjugated linoleic acid (CLA) on fatty acid composition and key enzymes of fatty acid oxidation in liver and muscle of geese. A total of 192 1-day-old geese were randomly assigned to 1 of 4 dietary groups, and were fed for 56 days on diets containing 2.5% soybean oil (group A, control group) or 2.0% soybean oil with 0.5% CLA (group B), 1.0% soybean oil with 1.5% CLA (group C), and 2.5 % CLA (group D). Geese fed CLA had a decreased abdominal fat percentage (AFP) (P < 0.01) compared with the control. It was observed that dietary CLA levels had a significant effect on the body weight, weight gain, feed conversion rate (FCR) (P < 0.05), and feed intake (P < 0.01). Fatty acid composition showed a significant increase of the biologically active cis-9, trans-11 and trans-10, and cis-12 CLA isomers in both liver and muscle of geese fed CLA (P < 0.01). Dietary CLA led to an increase (P < 0.01) in saturated fatty acid (SFA) and a reduction in monounsaturated fatty acid (MUFA) (P < 0.05) concentrations in both liver and muscle. In liver, dietary CLA increased (P < 0.05) acyl CoA oxidase (ACO) activity, but did not affect carnitine palmitoyltransferase-I (CPT-I) activity compared with the control. CPT-I activity was significantly increased by 2.5% dietary CLA in muscle, where ACO activity was decreased at 1.5% CLA level. The results obtained suggested that geese can successfully incorporate CLA in both liver and muscle, which could be beneficial in the human diet, through provision of bioactive fatty acids with no detrimental effects on n-3 PUFA levels.

Pathogenesis Of Influenza A Virus: Inhibition Of Monocyte Differetiation Into Dendritic Cell, Saikat Boliar Jan 2009

Pathogenesis Of Influenza A Virus: Inhibition Of Monocyte Differetiation Into Dendritic Cell, Saikat Boliar

University of Kentucky Doctoral Dissertations

Dendritic cells (DC) are a heterogeneous population of hematopoietic cells that play a versatile role in orchestrating immune responses against an array of invading pathogens, including influenza virus. These cells reside in lymphoid organs as well as in non-lymphoid tissues such as mucosal surfaces of respiratory and gastro-intestinal system. Recent investigations have suggested that in the steady state, dendritic cells are derived mainly from bone marrow precursor cells without a monocytic intermediate whereas during inflammation or infection, monocytes readily differentiate to generate monocyte derived dendritic cells (MoDC). The ability of virus infected monocytes to differentiate into MoDC was investigated and …

Pyrilamine In The Horse: Detection And Pharmacokinetics Of Pyrilamine And Its Major Urinary Metabolite O-Desmethylpyrilamine, L. Dirikolu, A. F. Lehner, J Daniel Harkins, W. E. Woods, W. Karpiesiuk, R. S. Gates, M. Fisher, Thomas Tobin Jan 2009

Pyrilamine In The Horse: Detection And Pharmacokinetics Of Pyrilamine And Its Major Urinary Metabolite O-Desmethylpyrilamine, L. Dirikolu, A. F. Lehner, J Daniel Harkins, W. E. Woods, W. Karpiesiuk, R. S. Gates, M. Fisher, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Pyrilamine is an antihistamine used in human and veterinary medicine. As antihistamines produce central nervous system effects in horses, pyrilamine has the potential to affect the performance of racehorses. In the present study, O-desmethylpyrilamine (O-DMP) was observed to be the predominant equine urinary metabolite of pyrilamine. After intravenous (i.v.) administration of pyrilamine (300 mg/horse), serum pyrilamine concentrations declined from about 280 ng/mL at 5 min postdose to about 2.5 ng/mL at 8 h postdose. After oral administration of pyrilamine (300 mg/horse), serum concentrations peaked at about 33 ng/mL at 30 min, falling to <2 ng/mL at 8 h postdose. Pyrilamine was not detected in serum samples at 24 h postdosing by either route. After i.v. injection of pyrilamine (300 mg/horse) O-DMP was recovered at a level of about 20 ̄g/mL at 2 h postdose thereafter declining to about 2 ng/mL at 168 h postdose. After oral administration, the O-DMP recovery peaked at about 12 ̄g/mL at 8 h postdose and declined to <2 ng/mL at 168 h postdose. These results show that pyrilamine is poorly bioavailable orally (18%), and can be detected by sensitive enzyme-linked immunosorbent assay tests in urine for up to 1 week after a single administration. Care should be taken as the data suggest that the withdrawal time for pyrilamine after repeated oral administrations is likely to be at least 1 week or longer.

In order to evaluate heat tolerance, physiological constants of 32 cows were measured (Chinampo: n = 12; Holstein: n = 10; Jersey: n = 10). From June to December 2006, rectal temperature and respiratory rate were recorded every Monday at 0600 and 1700 h. Holstein rectal temperature was affected by heat most, followed by Jersey, and Chinampo (the most heat-resistant). Respiratory rate of the 3 breeds was affected by climatic factors, but the Holstein and Jersey cows registered values higher than those of Chinampo cows. With a temperature-humidity index (THI) above 72 the physiological variables of all 3 breeds increased. …
