Reducing The Public Health Impact Of Bovine Tuberculosis By Controlling Disease Transmission Between Cattle And White-Tailed Deer In Northwestern Minnesota, Barbara Knust

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis, caused by infection with Mycobacterium bovis, is a re-emerging zoonotic disease. It has staged a comeback by establishing infections in wildlife and cattle, creating the potential for human disease in locations where it was thought to be under control. In northwestern Minnesota, infected cattle and white-tailed deer were first discovered in 2005. A major bovine tuberculosis eradication campaign is underway in the state, with multiple efforts employed to control M. bovis infection in both cattle and deer populations. In order to effectively eradicate bovine tuberculosis in Minnesota, there is a need for better understanding of the factors …

Estrogen Receptor Alpha Localization In Thai Swamp Buffalo Oviduct During The Follicular And Luteal Phases, Paisan Tienthai, Kriengyot Sajjarengpong, Mongkol Techakumphu

The Thai Journal of Veterinary Medicine

Estrogens are known to be an important modulator for regulation of the reproductive function in female mammals. The specific receptor of estrogens in the buffalo reproductive tract, particularly in the oviduct, has not been explored yet in the expression pattern. This study was, therefore, undertaken to investigate the localization of the estrogen receptor alpha (ERα) in the oviduct of Thai swamp buffalo at the follicular and late luteal phases of the estrous cycle. The oviducts were collected from swamp buffalo genital tracts at the local abattoir and separated into the uterotubal junction (UTJ), isthmus, ampulla and infundibulum. Tissue distribution of …

Differential Gene Expression Associated With Postnatal Equine Articular Cartilage Maturation, Michael J. Mienaltowski, Liping Huang, Arnold J. Stromberg, James N. Macleod

Veterinary Science Faculty Publications

BACKGROUND: Articular cartilage undergoes an important maturation process from neonate to adult that is reflected by alterations in matrix protein organization and increased heterogeneity of chondrocyte morphology. In the horse, these changes are influenced by exercise during the first five months of postnatal life. Transcriptional profiling was used to evaluate changes in articular chondrocyte gene expression during postnatal growth and development.

METHODS: Total RNA was isolated from the articular cartilage of neonatal (0-10 days) and adult (4-5 years) horses, subjected to one round of linear RNA amplification, and then applied to a 9,367-element equine-specific cDNA microarray. Comparisons were made with …

The Effect Of Heterogeneous Infectious Period And Contagiousness On The Dynamics Of Salmonella Transmission In Dairy Cattle, Cristina Lanzas, S Brien, R Ivanek, Y Lo, P P. Chapagain, K A. Ray, P Ayscue, L D. Warnick, Y T. Grohn

Faculty Publications and Other Works -- Biomedical and Diagnostic Sciences

The objective of this study was to address the impact of heterogeneity of infectious period and contagiousness on Salmonella transmission dynamics in dairy cattle populations. We developed three deterministic SIR-type models with two basic infected stages (clinically and subclinically infected). In addition, model 2 included long-term shedders, which were defined as individuals with low contagiousness but long infectious period, and model 3 included super-shedders (individuals with high contagiousness and long infectious period). The simulated dynamics, basic reproduction number (R0) and critical vaccination threshold were studied. Clinically infected individuals were the main force of infection transmission for models 1 and 2. …

The Risk And Control Of Salmonella Outbreaks In Calf-Raising Operations: A Mathematical Modeling Approach, Cristina Lanzas, L D. Warnick, R Ivanek, P Ayscue, D V. Nydam, Y T. Grohn

Faculty Publications and Other Works -- Biomedical and Diagnostic Sciences

Salmonellosis in calves has economic and welfare implications, and serves as a potential source of human infections. Our objectives were to assess the risk of Salmonella spread following its introduction into a herd of pre-weaned calves and to evaluate the efficacy of control strategies to prevent and control outbreaks. To meet these objectives, we developed a model of Salmonella transmission within a pre-weaned group of calves based on a well documented outbreak of salmonellosis in a calf-raising operation and other literature. Intervention scenarios were evaluated in both deterministic and stochastic versions of the model. While the basic reproduction number (R0) …

The Effects Of Lactation And Negative Energy Balance On Kisspeptin-Stimulated Luteinizing Hormone And Growth Hormone In Dairy Cows, Brian K. Whitlock, Joseph A. Daniel, Robyn R. Wilborn, Herris S. Maxwell, Barbara P. Steele, James L. Sartin

Animal Science Publications and Other Works

Kisspeptin, a neuroendocrine regulator of gonadotropin releasing hormone, is hypothesized to integrate nutrition and hormones critical to metabolism and the regulation of reproduction. Since the negative energy balance of early lactation is associated with reduced fertility via suppression of gonadotropin secretion and enhanced growth hormone (GH) responsiveness, this experiment was designed to determine the effects of stage of lactation and negative energy balance on kisspeptin-10 (Kp-10) stimulated luteinizing hormone (LH) and GH concentrations. Five nonlactating [5.1 ± 0.8 (SEM) years; 577 ± 19 kg body weight (BW)] and five lactating [4.1 ± 0.6 years; 608 ± 11 kg BW] multiparous …

Antibody Responses Of Cervids (Cervus Elaphus) Following Experimental Mycobacterium Bovis Infection And The Implications For Immunodiagnosis, Noel P. Harrington, Om P. Surujballi, John F. Prescott, J. Robert Duncan, W. Ray Waters, Konstantin Lyashchenko, Rena Greenwald

Michigan Bovine Tuberculosis Bibliography and Database

Captive and free-ranging wildlife animals are implicated in the maintenance and transmission of bovine tuberculosis and therefore pose a significant obstacle to eradication of the disease from domestic livestock. The current antemortem diagnostic method, the intradermal tuberculin skin test, is impractical for routine use with many wild animals. Antibody-based assays are particularly attractive because the animals are handled only once and immediate processing of the sample is not required. This report characterizes the antibody responses of red deer-elk hybrids (Cervus elaphus) against Mycobacterium bovis and subsequently evaluates the diagnostic performance of select antigens in a rapid-test format. Sequential …

Behavioural Analysis Of A Nociceptive Event In Fish: Comparisons Between Three Species Demonstrate Specific Responses, Siobhan C. Reilly, John P. Quinn, Andrew R. Cossins, Lynne U. Sneddon

Sentience Collection

Nociception is the sensory mechanism by which potentially harmful stimuli are detected in animals and humans. The behavioural responses to noxious stimulation have been studied in two fish species thus far. However, since species-specific differences are seen in mammals, more species need to be examined to determine whether nociceptive responses are generic in fish. The present study investigated the behavioural and respiratory response to an acute noxious or potentially painful stimulus in common carp (Cyprinus carpio), zebrafish (Danio rerio) and rainbow trout (Oncorhynchus mykiss). Behavioural parameters such as frequency of swimming, use of cover and any anomalous behaviour were measured …

Got Controversy - Milk Does, Margaret Sova Mccabe

Law Faculty Scholarship

This article analyzes ongoing controversy over how to best label rBST-free milk. Recombinant bovine somatotropin is a genetically engineered drug administered by some farmers to their dairy herds to increase milk production. FDA first approved its use in 1994, despite great controversy. The FDA also issued labeling guidelines that allowed voluntary disclosure of rBST-free milk, so long as it carried the disclaimer that no difference could be detected between milk produced with rBST and rBST-free. The controversy continues today as consumers express a preference for rBST-free milk and many rBST-free producers label their milk this way. "Conventional" milk (with rBST) …
