Four bovine adenovirus type 3 isolates, recovered from different areas in Oregon and Washington, were compared antigenically with the original prototype strain which was isolated in England. The fluorescent foci assay method was used to quantitatively establish viral titers. A serum-viral neutralization test was performed with a standard dose of...
An enzyme-linked immunosorbent assay was developed to
measure specific antibody response in bovine sera to bovine
adenovirus type 3 (BA3), an etiologic agent of respiratory
disease causing economic losses annualy to the cattle
industry. Observed endpoint titers were determined using
the intersection point from optical density values of
serially diluted...
Fifteen adenoviruses from cattle, sheep, horses, and llamas were studied by virus neutralization to determine their degree of antigenic similarity. Prototype viruses included bovine adenoviruses species 1-8, ovine adenoviruses species 5 and 6, and equine adenovirus species 1. Unclassified viruses that were compared to the prototype viruses were isolated from...
