| a longitudinal study of bovine coronavirus enteric and respiratory infections in dairy calves in two herds in ohio. | this prospective longitudinal study examined the epidemiology and disease syndrome associated with bovine coronavirus (bcv) infections in a cohort of 8 conventional calves from 0 to 120 days of age, in two dairy herds in ohio. the periods of respiratory shedding of bcv were determined by direct immunofluorescent (dif) staining of nasal epithelial cells and elisa of nasal swab supernatant fluids. the periods of fecal shedding of bcv were determined by elisa and immunoelectron microscopy (iem). th ... | 1990 | 2162099 |

| detection of respiratory and enteric shedding of bovine coronaviruses in cattle in an ohio feedlot. | recently, bovine coronavirus (bcv) has been isolated from new cattle arrivals to feedlots, but the association between respiratory and enteric infections with bcv in feedlot cattle remains uncertain. fecal and nasal swab samples from 85 ohio agricultural research and development center (oardc) feedlot cattle averaging 7 months of age were collected at arrival (0) and at 4, 7, 14, and 21 days postarrival (dpa). an antigen capture enzyme-linked immunosorbent assay (elisa) was used to detect concur ... | 2002 | 12152810 |
