Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine
Graduate Theses and Dissertations
Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …
Associations Among Beef Cattle Genotypes, Neospora Caninum Infection, And Reproductive Performance, Ryan James Page
Associations Among Beef Cattle Genotypes, Neospora Caninum Infection, And Reproductive Performance, Ryan James Page
Graduate Theses and Dissertations
Reproductive performance is crucial for sustained financial success in the beef cattle industry. This dissertation includes a population study that quantified the incidence of Neospora caninum infections in the central region of the United States and tested its relationship with reproductive performance in beef cattle. Trial one of that study concluded that 6.9% of open, replacement heifers (n = 1306) tested seropositive. The second trial in that project found that 9.6% of the breeding age females (n = 500) tested were seropositive for Neospora caninum; and that state in which the cattle lived and age impacted (P < 0.05) infection rate. Breed composition, number of farm dogs on the ranch, and use of total mixed rations were not associated (P > 0.1) with seropositive …

Investigating The Morphology Of Iprgcs In Control Vs. Glaucomatous Retinas, Samantha Cook
Williams Honors College, Honors Research Projects
Glaucoma is a build-up of pressure in the eye that leads to the gradual loss of sight. The intention of this study was to investigate how glaucoma affects intrinsically photosensitive Retinal Ganglion Cells (ipRGCs). These cells contain melanopsin, a photopigment, that enables the cells to react to light. Four-month-old control and five-month-old glaucoma mice retinas were dissected, stained using primary and secondary antibodies, then traced using ImageJ’s Simple Neurite Tracer. There were no significant differences in soma size, total dendritic length, dendritic field size, and dendritic field diameter between control and glaucoma ipRGCs. However, further research is needed to provide …
