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...
A study was undertaken to determine the prevalence of virus infection in lambs undergoing respiratory tract disease (RTD). The investigation was divided into three study groups and consisted of lambs which were 4 to 5 months of age. In the first group (N=200), paired serum samples were taken from lambs...
Six 3 to 4 weeks old, cesarian-derived lambs were inoculated with ovine an adenovirus isolate 475N. Inoculated lambs showed moderate clinical signs of respiratory distress, conjunctivitis, and loose feces during the 10-day observation period. Virus was detected from nasal and conjunctival swabs starting on postinoculation day (PID) 2.
Virus was...
