In vitro fertilization (IVF) and micro-injection of DNA are reproductive technologies available to enhance the genome of production animals. Immune cell function is poorly understood in calves produced by these reproductive methods. Based on economic value and potential use, characterizing immune cell function would aid in better understanding of both management and medicine of calves produced by enhanced reproductive technologies. The objective of this study was to evaluate specific immune cell parameters in these calves., American Association of Bovine Practitioners Proceedings of the Annual Conference, 2000

The response of phagocytic cells to Pasteurella haemolytica is difficult to study in situ. Available assays to study the function of these cell types often do not accurately reflect the physiology of the cell in response to bovine pasteurellosis. This study compared granulocyte phagocytosis of fluorescent beads and fluorescent bacteria using flow cytometry. Development of an in vitro assay would provide a model to study nutrient and pharmaceutical effects on the immune response to Pasteurella infections. It would also allow for future studies of the pathogenesis of not only bovine pasteurellosis but other diseases., American Association of Bovine Practitioners Proceedings of the Annual Conference, 2000
