Aim: The aim of this thesis was to investigate the use of salivary Epstein-Barr virus (EBV) DNA as a marker of in vivo immunity in response to training and nutritional intervention. Methods: Initially, an assay for the detection of EBV DNA in saliva was developed which was subsequently used to detect the concentration of EBV DNA in samples collected in subsequent studies. The potential role of EBV as a predictor of URTI in response to endurance exercise are presented, along with the outcome of nutritional interventions, with chapters investigating the effects of supplementation with carbohydrate, and Chlorella pyrenoidosa. Finally, data from all four of these chapters were consolidated, and the role of salivary EBV DNA as a marker of in vivo immunity investigated. Outcome: The main finding from this thesis is that salivary EBV DNA does not appear to be a useful marker of in vivo immunity based on the present data. EBV concentration was not a predictor of URTI, nor was there a relationship between EBV concentration and SIgA concentration or secretion rate, or the absolute change or percentage change in EBV from pre-post exercise and the absolute and percentage change in SIgA concentration or secretion rate.
