Molecular Epidemiological Investigation of Salmonella and Its Antibiotic Resistance Patterns in Swine Production Units
In conclusion, advanced molecular genotyping and spatial statistical methods used in the study of Salmonella transmission and its antibiotic resistance have contributed to an expanded understanding of the epidemiology of Salmonella.

Elicitation and Characterization of Antibodies With Idiotypic (Ab1) and Anti-Idiotypic (Ab2) Reactivity: Epibodies
Studies of the regulatory idiotypic network have routinely assayed idiotypic (Ab1) and anti-idiotypic (Ab2) levels in the immune response. This work is a follow up of a previous study in which Ab1 and Ab2 responses to the hapten DNP were found to be similar in terms of magnitude and kinetics …

Acute Effects of Episodic PCB Congeners on the Hypothalamo -Pituitary-Thyroid (Hpt) Axis in Weanling Female Rats
These studies demonstrate that brief exposure to ortho-substituted PCBs can cause alterations in the HPT axis in immature animals. The data indicate that ortho-PCBs 95 or 101 cause secondary or pituitary-related hypothyroidism. There is also evidence that these PCBs may be affecting the HPT-axis …

Cardiac Vasoactive Peptides in Hypertrophic Cardiomyopathy of Cats
In conclusion, ANP and BNP are normally produced and stored in the atria. With HCM, significant peptide and mRNA expression of BNP is found in the ventricles, while protein and gene expression of ANP remains mainly in the atria. This pattern agrees with increases in plasma concentrations of both …

Disposition and Toxic Effects of Polychlorinated Biphenyls Following Different Routes of Exposure
The differences in disposition and toxic effects of PCBs caused by different exposure routes were demonstrated. Therefore, to better estimate human health effects following exposure to PCBs, it is crucial to identify PCB congener profiles in the exposure sources.

Factors and Mechanisms Involved in Epithelial Injury and Repair of Equine Colon
We concluded that acetylcysteine and glutamine might be beneficial in the treatment of horses with gastrointestinal disease. The increase of mucosal permeability caused by acetylcysteine may be caused by the mucolytic properties of acetylcysteine. A lower dose may prevent mucolysis while allowing …

Musculoskeletal Conformation of the Normal and Diseased Canine Stifle With Emphasis on Patella Luxation and Cranial Cruciate Ligament Deficiency
The second objective was to identify the morphometric characteristics of the pelvic limb that may explain breed predisposition to CCL deficiency. Thirty Labrador Retrievers were included in a cross-sectioned prospective clinical study. Musculoskeletal parameters were measured using physical …

Pathogenesis of Fumonisin Toxicosis in Swine
Fumonisins are a recently identified group of mycotoxins that are worldwide contaminants of corn produced by Fusarium moniliforme. They induce species-specific disease, including leukoencephalomalacia in horses and pulmonary edema in pigs, but little is known about the pathogenesis of disease. …

Pseudorabies Virus Latency Associated Transcript Gene: Expression, Regulation, and Role in the Establishment of Latency in Swine
One unique biological feature about herpesvirus infections is that they can become latent following the primary infection. Studies presented in Chapter 1 demonstrate that the PrV latency associated transcripts (LAT) gene is also active during an in vitro productive infection. Three polyadenylated …

Visualizing Cell Migration in Situ
Cell migration has been studied extensively by manipulating and observing cells bathed in putative chemotactic or chemokinetic agents on planar substrates. This system is attractive since the cells and their molecular components can be readily imaged and matrix and soluble parameters easily …

Steroid Hormone Regulation of Implantation
Steroid hormones Estrogen (E) and Progesterone (P) coordinate to regulate the process of embryo implantation, the process by which embryo attaches to the uterine epithelium. The uterus in response to the implanting embryo undergoes various changes to help create a suitable environment for the …

Mechanisms of Ionophore Toxicoses: Laidlomycin Propionate Toxicosis in the Horse and Monensin, Laidlomycin, and Laidlomycin Propionate in Muscle Cultures
Cellular effects of monensin, laidlomycin, and LP were evaluated after 24-hour exposure in 3-day (myoblasts) and 14-day ($>$90% myotubes) cultures of E-63 rat skeletal muscle cells. Each of these ionophores induced dose-dependent increases in lactate concentrations, decreases in pyruvate …

Estrogenic Effects of Genistein in Ovariectomized Gilts
Genistein, has a range of estrogenic actions, however only limited research has been done to investigate its effects in swine. The objective was to characterize the effects of administration of a graded dose of genistein on tissues known to be estrogen sensitive. Thirty-four post-pubertal gilts …

Influence of Prepubertal Dietary Protein and Age at First Calving on the Performance, Reproduction and Lactation of Replacement Beef Heifers
The objective of this research was to evaluate the effects of prebreeding dietary protein level and age at first calving on the performance, reproduction and lactation of replacement beef heifers. Dietary protein levels ranging from 11.7% to 22.6% CP were tested in six experiments using several …

Avian Infectious Bronchitis Virus: A Tropism for the Rooster Reproductive Tract and Effects on Reproductive Performance
The epididymal region of the rooster consists of the rete testes, the efferent ductules and the epididymal duct. In the epididymal region, the spermatozoa gain the ability to move and acquire surface proteins. The specialized microenvironment of the epididymal region is vital for these developments …

Investigation of Exogenous Gonadotropin Treatment for Prevention of Non-Infectious Infertility and for Embryo Production Using the Prepubertal Gilt as a Model
Reliable methods for consistent prevention of non-infectious infertility and production of embryos are limited for swine. In many species, FSH is favored over chorionic gonadotropins for induction of estrus and ovulation, yet little data are available to indicate its value for use in pigs. …

Studies on the Effects of Alkalizing Agents on Acid -Base Balance in Horses
"Alkalizing agents have been used prior to competition in the Standardbred Racing Industry to improve performance. The physiological response of horses administered alkalizing agents is increased blood pH and bicarbonate ion concentration. In human subjects, an ergogenic effect has been found after …

Starch Source, Fraction, and Processed Form Affect in Vitro and in Vivo Digestion and Glycemic Responses in Dogs
Starch plays an important role in the nutritive value of many foods and diets consumed by animals. Not only does starch provide an excellent source of ME, it also influences the way in which products can be manufactured due to its important rheological and other functional properties such as …
