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.

Spatial Ecology Of Raccoons Related To Cattle And Bovine Tuberculosis In Northeastern Michigan, Todd Atwood, Thomas Deliberto, Holly Smith, Justin Stevenson, Kurt C. Vercauteren
Michigan Bovine Tuberculosis Bibliography and Database
In 1995, Mycobacterium bovis, the causative bacterium of bovine tuberculosis (bTB), was detected in 5 beef cattle operations in Alcona County, Michigan, USA. In accordance with Federal law, the operations were depopulated to prevent the spread of bTB. Subsequent wildlife surveillance programs identified high prevalence of M. bovis in mesocarnivores, including raccoons ( Procyon lotor), which suggested that raccoons may be complicit in vectoring the pathogen among livestock operations. Our goal was to develop an empirical basis for generating hypotheses about the likelihood for raccoons to mediate the transmission of bTB to livestock. We found intersexual differences in …

1. Understanding the effects of disease is critical to determining appropriate management responses, but estimating those effects in wildlife species is challenging. We used bovine tuberculosis (BTB) in the African buffalo Syncerus caffer population of Kruger National Park, South Africa, as a case study to highlight the issues associated with estimating chronic disease effects in a long-lived host.
2. We used known and radio-collared buffalo, aerial census data, and a natural gradient in pathogen prevalence to investigate if: (i) at the individual level, BTB infection reduces reproduction; (ii) BTB infection increases vulnerability to predation; and (iii) at the population level, …

Economic Impact Of Bovine Tuberculosis On Minnesota’S Cattle And Beef Sector, Brian Buhr, Kyle Mckeever, Kenji Adachi
Michigan Bovine Tuberculosis Bibliography and Database
In September 2005, the first case of bovine tuberculosis (BTB) in 34 years was discovered in Minnesota and led to a loss of Minnesota’s bovine TB free status. In October 2007 and January and February 2008, four additional cattle herds and deer infected with BTB were discovered in Roseau and Beltrami counties and Minnesota’s BTB status was changed from “modified accredited advanced” to “modified accredited” in April 2008. Each of these designations has increased regulatory requirements (and costs) for animal testing, record keeping, eradication practices, slaughtering and shipments of cattle within state and across state lines.

Michigan Bovine Tuberculosis Bibliography and Database
Surveillance and control activities related to bovine tuberculosis (TB) in free-ranging, Michigan white-tailed deer (Odocoileus virginianus) have been underway for over a decade, with significant progress. However, foci of higher TB prevalence on private lands and limited agency ability to eliminate them using broad control strategies have led to development and trial of new control strategies, such as live trapping, testing, and culling or release. Such strategies require a prompt, accurate live animal test, which has thus far been lacking. We report here the ability of seven candidate blood assays to determine the TB infection status of Michigan …

Tuberculosis: A Re-Emerging Disease In Animals And Humans, Charles O. Thoen, Philip A. Lobue, Donald A. Enarson, John B. Kaneene, Isabel N. De Kantor
Michigan Bovine Tuberculosis Bibliography and Database
Tuberculosis continues to be an important disease both in humans and animals. It causes morbidity, mortality, and economic loss worldwide. The occurrence of Mycobacterium bovis disease in humans, domesticated and wild animals confirms the relevance of this zoonosis. M. bovis in humans continues to be reported in industrialized countries and in immigrants from regions of the world where tuberculosis in cattle is endemic. The real incidence of M. bovis in humans in developing countries continues to be roughly underestimated due to the scarcity of appropriate laboratory facilities to isolate and to differentiate M. bovis strains. In Latin America, less than …

School of Veterinary and Biomedical Sciences: Faculty Publications
Current vaccines are only partially effective against porcine reproductive and respiratory syndrome (PRRS) virus infection because they elicit a weak immune response that is not fully protective. PRRS is the most economically significant disease facing the swine industry today, costing U.S. pork producers at least $560 million annually. Despite substantial research efforts the exact components of a protective anti-PRRSV immune response are still not known, thus we are testing alternate approaches to evaluate immunity and genetic resistance to PRRSV. We used host genomics to compare different lines of pigs and look for factors that correlated with PRRSV resistance/ susceptibility. Viremia, …
Innate Immune Responses In The Central Nervous System Following Toll-Like Receptor (Tlr) 7 And Tlr9 Activation, Niranjan Babu Butchi
Innate Immune Responses In The Central Nervous System Following Toll-Like Receptor (Tlr) 7 And Tlr9 Activation, Niranjan Babu Butchi
LSU Doctoral Dissertations
Activation of astrocytes and microglia and the production of proinflammatory cytokines and chemokines are often associated with virus infection in the central nervous system (CNS) as well as a number of neurological diseases of unknown etiology. These inflammatory responses may be initiated by recognition of pathogen-associated molecular patterns that stimulate toll-like receptors (TLRs). Recent studies demonstrated that TLR9 family receptors play a role in neuropathogenesis and the agonists of these receptors may be used in therapeutics treatment of brain tumors and viral infections. However, we lack the basic understanding of how these receptors function in the CNS. In the present …

Theses
The issue of food safety is a growing concern to Irish agriculture and to the food industry. In the last twenty years, many novel pathogens, which can cause concern to the food industry, have been identified. Organisms such as Verocytotoxigenic Escherichia coli (VTEC) cause hemorrhagic colitis and Haemolytic Uremic Syndrome (HUS), which is the major cause of acute renal failure in children in many countries, and it’s presence in food is a cause of growing concern. Other pathogens causing concern are those implicated as causative agents of Acute Gastroenteritis (AGE) and these can be bacterial, viral and parasitic organisms.

Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson
Effects Of Clenbuterol On Skeletal And Cardiac Muscle In Horses, Jessica Thompson
LSU Master's Theses
Clenbuterol is a commonly prescribed β2-adrenergic agonist approved for veterinary use as a bronchodilator in horses with reactive and obstructive airway disease. Potential for abuse of this drug in the horse industry is substantial, due to the perceptions that clenbuterol increases performance and lean muscle mass. Although anabolic effects have been confirmed in multiple species, recent studies into the effects of clenbuterol in exercising horses suggest that clenbuterol doses within therapeutic ranges negatively impact aerobic capacity and cardiac function. Results of studies in murine models demonstrate that clenbuterol directly induces skeletal and cardiac muscle cell death at high doses. Three …
Chondrocyte Death In Canine Osteochondral Explants Exposed To 0.5 Percent Bupivacaine, Geoffrey Stuart Hennig
Chondrocyte Death In Canine Osteochondral Explants Exposed To 0.5 Percent Bupivacaine, Geoffrey Stuart Hennig
LSU Master's Theses
Objective: Our in vitro study evaluated chondrocyte death in canine articular cartilage exposed to 0.5% bupivacaine without (B) and with methylparaben (BP) and compared the viability with intact (SI) and mechanically debrided surfaces (SR). We hypothesized that B or BP would cause chondrocyte death in vitro in a time dependent manner and that chondrocyte death would be increased in SI osteochondral cores compared to SR. Materials and Methods: Intact cartilage cores with underlying subchondral bone were collected aseptically from both humeral heads of 16 fresh canine cadavers. Joints from each dog were randomly assigned to SI or SR. Ten osteochondral …
Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury
Influence Of Tick Transmission On The Host Response To Rickettsial Infection, Soma Chowdhury
LSU Master's Theses
Several members of the spotted fever group (SFG) of Rickettsia are transmitted to the host through infected ixodid (hard) ticks, which can serve as both vectors and reservoirs. Multiple studies have demonstrated that ticks secrete proteins into the bite site of the host that suppress innate and adaptive immune responses. While this suppression of immune responses is beneficial to the tick, it may also be beneficial to the transmitted Rickettsia. We hypothesize that Rickettsia utilize the tick’s ability to alter the host immune response at the tick feeding site to successfully establish infection. In the current study, we analyzed how …
Quantitative Real-Time Polymerase Chain Reaction (Qpcr) Assay As A Molecular Tool To Assess Rickettsial Replications In Tick Hosts, Andrea S. Zanetti
Quantitative Real-Time Polymerase Chain Reaction (Qpcr) Assay As A Molecular Tool To Assess Rickettsial Replications In Tick Hosts, Andrea S. Zanetti
LSU Master's Theses
During the past century, many species of the Spotted Fever Group Rickettsia (SFGR)have been described, especially, through the introduction of a variety of molecular techniques applied to detect rickettsiae inside of their host. In this study we developed a quantitative realtime polymerase chain reaction (qPCR) assay (1) to characterize the growth and the distribution of a SFGR of unrecognized pathogenicity in naturally infected Amblyomma americanum ticks during physiological events; and (2) to terminate the influence of the host cell specificity in the replication patterns of recognized and unrecognized SFGR during a reciprocal rickettsiae challenge in both mammalian and tick cell …

The Effects Of Feeding Level And Stocking Density On The Growth And Feed Efficiency Of Himri Barbel Fry, Barbus Luteus (Heckel, 1843), Kaya Gökçek, Yalçin Tepe
Turkish Journal of Veterinary & Animal Sciences
Two stocking densities (20 and 40 fry/80-l tank) with 4 feeding rates (2.5%, 5.0%, 7.5%, and 10.0% body weight/day) were used to determine the optimum feeding level for himri barbel fry during a 60-day culture period. Water quality parameters (temperature, dissolved oxygen, pH, and total ammonia nitrogen) were monitored during the experiment. Final body weight and specific growth rate (SGR) was significantly lower with the 2.5% feeding rate than with the others, at both stocking densities; however, no significant differences were observed between the other feeding rates and between stocking densities. The best feed conversion ratio (FCR) of 1.37 was …

This study was conducted to determine some properties of set and stirred type yoghurts containing 0.5% and 1% garlic (Allium sativum L.) during storage period of 28 days at 4±1 °C. Some microbiological, physical, chemical, and sensory properties of yoghurts were determined in days 1, 7, 14, 21, and 28 of the storage period. Coliform bacteria were not detected in all samples during the storage period ( 0.05) and sensory scores of yoghurts decreased during the storage period. It was also shown that the control group could be safely consumed up to day 7 of storage while garlic groups could …
