Anesthetic Effects Of Dexmeditomidine-Tiletamine/Zolazepam Combination In Cats Undergoing Ovariohysterectomy, Nunnapas Jiwlawat, Cholawat Pacharinsak, Sumit Durongphongtorn

The Thai Journal of Veterinary Medicine

Common injectable anesthetics in cats are alpha-2 receptor agonists and tiletamine/zolazepam. Xylazine shows higher rate of side effects because its lower specificity to alpha-2 receptors than dexmeditomidine. However, the use of drug combinations in cats is not much known. Therefore, alternative anesthetic combination should be investigated. Here, we examined the use of tiletamine/zolazepam with two doses of dexmedetomidine in cats. A total of 24 female cats, weight 3.05 ± 0.10 kg (mean ± SEM). Cats were randomly blinded given intramuscularly injection (IM) with either of such drug combination, representing dosage of low dose dexmedetomidine 7.5 μg/kg with tiletamine/zolazepam 3 mg/kg; …

Optimal Infusion Rate Of Hypertonic Saline To Encephalic Vessel Vasodilatation Using Magnetic Resonance Imaging In Normovolemic Dogs, Yoshiki Murakami, Kenji Tsukano, Haruyuki Hirata, Hiroshi Koie, Kazuyuki Suzuki

The Thai Journal of Veterinary Medicine

This study aimed to investigate, using magnetic resonance imaging, whether continuous hypertonic saline (HSS) infusion induces a superior vasodilating effect on the encephalic vessels compared to bolus infusion in dogs. The relative cross-sectional area of superior sagittal sinus increased to 1.96±0.09 and 1.69±0.31 times of the pre-value in the continuous and bolus groups, respectively, at t=30 min (p<0.001). However, the relative cross-sectional area of superior sagittal sinus was larger in the continuous group than that in the bolus group (p<0.001). The results suggest that continuous infusion of HSS might be superior to bolus infusion in inducing vasodilatation of the encephalic circulation.

Sporadic Worldwide “Clusters” Of Feed Driven Zilpaterol Identifications In Racing Horses: A Review And Analysis, Jacob Machin, Kimberly Brewer, Abelardo Morales Briceno, Clara Fenger, George Maylin, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Zilpaterol is a β2-adrenergic agonist medication approved in certain countries as a cattle feed additive to improve carcass quality. Trace amounts of Zilpaterol can transfer to horse feed, yielding equine urinary “identifications” of Zilpaterol. These “identifications” occur because Zilpaterol is highly bioavailable in horses, resistant to biotransformation and excreted as unchanged Zilpaterol in urine, where it has a 5 day or so terminal half-life.

In horses, urinary steady-state concentrations are reached 25 days (5 half-lives) after exposure to contaminated feed. Zilpaterol readily presents in horse urine, yielding clusters of feed related Zilpaterol identifications in racehorses. The first cluster, April …


Comparison Of Abdominal Computed Tomography To Ultrasound In The Diagnosis Of Canine Biliary Disease Manifesting As Acute Abdominal Signs, Shanna Christine Marroquin 2022 Mississippi State University

Comparison Of Abdominal Computed Tomography To Ultrasound In The Diagnosis Of Canine Biliary Disease Manifesting As Acute Abdominal Signs, Shanna Christine Marroquin

Theses and Dissertations

Biliary diseases are uncommon, potentially fatal causes of acute abdomen in dogs. Little information is present comparing the performance of computed tomography (CT) to ultrasound in identifying canine biliary pathology. Thirty-five client-owned dogs presenting for acute abdomen signs received an abdominal ultrasound and contrast-enhanced abdominal CT. Two authors reviewed the randomized, anonymized CT and ultrasound studies. Twenty-eight dogs had biliary pathology and seven dogs serving as controls had no evidence of biliary disease. The final diagnoses of patients with biliary pathology included cholelithiasis, gallbladder mucoceles, cholangiohepatitis/cholangitis, extrahepatic biliary obstruction, gallbladder wall edema, gallbladder wall mass, and cystic mucosal hyperplasia. Computed …

Seasonal Variation And Tracking Of Climate Niche Of A Migratory Bird, Javier Gutiérrez Illán, Guiming Wang, D. Tommy King, Fred L. Cunningham

USDA Wildlife Services - Staff Publications

Migratory birds inhabit different areas during breeding and non-breeding seasons. Depending on the time of the year, they may utilize different resources available in seasonal habitats, but also are subjected to changing climate regimes during their annual life cycle. Migratory birds may adopt ecological niche tracking to cope with different environmental conditions between breeding and non-breeding grounds. The American White Pelican (Pelecanus erythrorhynchos, hereafter ‘AWPE’) is a short-distance migrant between the Gulf of Mexico coastal regions (nonbreeding grounds) and the Northern Great Plains (breeding grounds) of Canada and the US. The American White Pelican is a piscivore, feeding …


The Impact Of The Covid-19 Pandemic On Antimicrobial Stewardship Practices And Their Effect On Veterinary Medicine, Erin N. Bradstreet 2022 University of Maine - Main

The Impact Of The Covid-19 Pandemic On Antimicrobial Stewardship Practices And Their Effect On Veterinary Medicine, Erin N. Bradstreet

Honors College

Antimicrobials are essential in the treatment of diseases in both humans and animals, but antimicrobial resistance threatens their efficacy. As more microorganisms become resistant to an ever-growing list of antimicrobials, diseases that used to be simple to treat are becoming increasingly difficult to manage. The major factors contributing to antimicrobial resistance are overuse and misuse of antimicrobials. In order to combat the problem of resistance, antimicrobial stewardship programs that aim to improve antimicrobial prescribing and use practices are becoming increasingly widespread. These programs are quite common in human medicine, but the COVID-19 pandemic disrupted many aspects of life, including antimicrobial …


Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian Gilbert 2022 University of Arkansas, Fayetteville

Time Course Investigation Of The Dermal Leukocyte Response To Lipoteichoic Acid In Chickens, Ian Gilbert

Animal Science Undergraduate Honors Theses

Lipoteichoic acid (LTA) is component of the cell wall of Gram-positive bacteria that stimulates inflammation during bacterial infection. However, few studies have investigated the in vivo immune response to LTA, and none of the in vivo studies done have been performed in birds. For this project, the pulp (a skin-derivative) of growing feathers (GFs) of chickens were used as a test site to investigate the in vivo effects of intradermally injected LTA. In Study 1, the pulp of 12 GFs of 11-week-old Light-brown Leghorn (LBL) males were injected with 10 μL of differing concentrations of LTA (0.1, 1.0, 10, 100 …

USDA Wildlife Services - Staff Publications

Invasive mice (Mus spp.) can negatively impact island species and ecosystems. Because fewer island rodent eradications have been attempted for mice compared to rats (Rattus spp.), less is known about efficacy and palatability of rodenticide baits for mouse eradications. We performed a series of bait acceptance and efficacy cage trials using a standard formulation of brodifacoum-based rodenticide on wild-caught mice from Sand Island, Midway Atoll, to help inform a proposed eradication there. Mice were offered ad libitum brodifacoum pellets along with various alternative food sources, and a “no choice” treatment group received only bait pellets. Mortality in the no choice …

Barriers To Client Compliance And Understanding Of Heartworm Prevention In The Canine Patient, Emily Fischels 2022 Murray State University

Barriers To Client Compliance And Understanding Of Heartworm Prevention In The Canine Patient, Emily Fischels

Honors College Theses

Dirofilaria immitis is a common and largely preventable mosquito-borne parasite that causes dirofilariasis, or heartworm disease, in a number of animal species. The necessity of heartworm prevention in the canine patient is undisputed and well-known among veterinary professionals, yet there are still many dogs not protected from this fatal parasite. Heartworm prevention traditionally requires a once-a-month administration of medication; therefore, its efficacy relies on owner compliance. The barriers to canines receiving heartworm prevention were assessed using a survey targeted at pet owners whose dogs have seen the veterinarian in the past year. The main barriers identified were inadequate client communication …

Evaluation Of Protective Efficacy Of Viral Vector Based Swine Influenza Vaccine And A Method For B Cell Culture For Monoclonal Antibody Generation, Sushmita Kumari

Dissertations & Theses in Veterinary and Biomedical Science

Influenza A virus of the swine (IAV-S) is an economically important swine pathogen that has the potential to spread to humans, thus posing an ongoing public health concern due to its zoonotic potential. Hemagglutinin (HA), the most abundant viral envelope protein, is known to be the key protective antigen. Anti-HA antibodies alone, have been shown to prevent IAV infection. In this study we evaluated the feasibility of a recombinant tri segmented Pichinde virus (PICV) as a viral vector to deliver IAV-S hemagglutinin antigen in pigs. Four groups of weaned pigs (T01-04) were immunized twice with PBS, rPICV-GFP as a vector …

Individual Trophic Niche Specialization In American Beaver (Castor Canadensis), Jimmy Taylor, Robert Francis, Scott Rush, Bronson Strickland, Guiming Wang

USDA Wildlife Services - Staff Publications

The American beaver (Castor canadensis) has been described as a choosy generalist at the species/population scale, yet observational studies have shown little variation in diet among individuals. We compared isotopic values of δ13C or δ15N taken from hair of 32 beaver, representing seven colonies in northern Alabama, USA to determine 1) if colonies of beaver show overlap in isotopic niche width as a result of the similar use of food resources and 2) if individual trophic niche specialization occurs within colonies. Total Trophic Niche Width varied across the wetland with the widest being twice …
