Linking the social environment to illness in farm animals
Contributor(s):: Proudfoot, Kathryn L., Weary, Daniel M., von Keyserlingk, Marina A. G.
Disease is one of the single largest issues facing food animal agriculture today. Risk factors for various diseases in cattle, swine and chickens include aspects of both the physical and social environment. In this paper we review literature linking the social environment to illness in farm...
Environmentally enriching American mink (Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour
Contributor(s):: Díez-León, María, Bursian, Steve, Galicia, David, Napolitano, Angelo, Palme, Rupert, Mason, Georgia
Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

Pets: Do They Enhance Our Immunity?
Contributor(s):: Vidhi Desai, Calvin Leung, Ye Rin Lim, Julie M. Fagan
Pets can be highly beneficial to the human health and may even aid in the development of the human immune system. Our study specifically targets the area of pet ownership and its effects on the immune system’s capabilities of different age and ethnic groups. To examine this, we conducted a...

Animal Exposure, Asthma and Allergies
Contributor(s):: Felicia Trembath
An estimated 62% of all United States households have one or more pet and more than 38% of households with pets have children under the age of 18 (Beck, 2010). Although the total number of pets in the United States does not seem to be increasing (AVMA, 2012), the relationship between people and...

The use of positive reinforcement in training zebra sharks ( Stegostoma fasciatum)
Contributor(s):: Marranzino, A.
Positive reinforcement training (PRT) was used on 4 adult zebra sharks, Stegostoma fasciatum, housed at the Downtown Aquarium, Denver, to determine the ability of zebra sharks to become desensitized to various stimuli associated with veterinary procedures. One male and 3 female sharks were...
Knowledge, attitudes, and practices related to pet contact by immunocompromised children with cancer and immunocompetent children with diabetes
Contributor(s):: Stull, J. W., Brophy, J., Sargeant, J. M., Peregrine, A. S., Lawson, M. L., Ramphal, R., Samson, L., Bowes, J., Weese, J. S.
Objective: To compare knowledge, attitudes, and risks related to pet contact in households with and without immunocompromised children. Study design: A questionnaire was distributed to parents of children diagnosed with cancer (immunocompromised; n=80) or diabetes (immunocompetent; n=251)...
The effect of conspecific removal on the behaviour and physiology of pair-housed shelter dogs
Contributor(s):: Walker, J. K., Waran, N. K., Phillips, C. J. C.
Dogs ( Canis familiaris) are a highly social species and within a shelter environment pair-housing is recommended to prevent the stress associated with social isolation. Separation of individuals which may have formed bonds in this environment is a usual occurrence, as a result of rehoming or...
Information need of owners regarding dog's healthcare, zoonotic diseases and marketing
Contributor(s):: Basarajappa, A. D., Rupasi, Tiwari, Rakesh, Roy, Davinder, Singh, Matt, V. T., Devan, Arora
The present study was purposively conducted at Clinical Complex, VeterinaryCollege, Hebbal, Bangalore; Referral Polyclinic, IVRI, Izatnagar; Veterinary polyclinic, GBPUAT, Pantnagar and Veterinary hospital, Palam, New Delhi, India. From each clinical complex, 50 pet dog owners were selected...
Review of human-animal interactions and their impact on animal productivity and welfare
Contributor(s):: Idrus, Zulkifli
Humans and animals are in regular and at times close contact in modern intensive farming systems. The quality of human-animal interactions can have a profound impact on the productivity and welfare of farm animals. Interactions by humans may be neutral, positive or negative in nature. Regular...
Sickness behaviours in ducks include anorexia but not lethargy

Childhood Allergies & Immunity
Long before evidence and research specifically defined the benefits of the human and animal bond, people routinely included animals in many aspects of their lives. Many not only viewed these...
Genetic and dietary effects on chicken heterophil function and immune response to Salmonella enteritidis
Contributor(s):: Sarah Beth Redmond, Susan J. Lamont (adviser)
The function of the chicken innate immune system against pathogens is affected by genetic background and immune modulating diet. Heterophils from broiler, Leghorn, and Fayoumi birds showed differential expression of immune genes when stimulated with Salmonella enteritidis (SE) bacteria, a...
Reduction in mucosal barrier markers with soy protein diet but not Lactobacillus rhamnosus GG in DSS-treated mice
Contributor(s):: Huanyi Jiang, Ruth S. MacDonald (adviser)
Inflammatory bowel disease (IBD) is a common ailment affecting people of all ages. Even though the pathogenesis of IBD has not been fully elucidated, there is evidence that it involves interactions between genetic susceptibility, aberrant activation of the immune system, and the environment....
Whole transcriptome response of chicken spleen and peripheral blood leukocytes to avian pathogenic Escherichia coli
Contributor(s):: Erin Elizabeth Sandford, Susan J. Lamont (adviser)
A greater understanding of the immune response after infection can form the necessary foundation of knowledge needed to enhance immunity through genetic selection. Whole genome microarrays allow for comprehensive analysis of the transcriptome. The transcriptomic responses of spleen and peripheral...
