Project description:Bovine rotavirus (BRV) and bovine coronavirus (BCV) infect intestinal villous epithelium in young cattle. A surgical model was adapted for neonatal calves in which a region of the jejunum was isolated from the digestive tract but lymph drainage, enervation and blood flow were maintained. Replicate sections of intestine (loops) were infected with either BRV or BCV and adjacent segments were injected with phosphate-buffered saline. Tissues were collected 18 hours post-infection. Four animals were used for BRV infection studies, and three animals were used for BCV infection studies. Microarray analyses provided a global evaluation of host gene expression patterns following BRV and BCV infection and changes in gene expression were validated by qRT-PCR analyses.
