  • Pathogenesis of bovine adenoviral infections in newborn calves

    Creator:
    Peterson, Patricia L.
    Abstract:
    Three newborn, colostrum deprived calves were inoculated by the intranasal, intratracheal, conjunctival and oral routes with a subgroup II bovine adenovirus strain 7T. An initial viremia and febrile response occurred in all calves with widespread dissemination of the virus through the body. Clinical signs consisted of pyrexia, soft feces and...

  • Vaccination studies with bovine adenovirus type 3 in a dairy calf herd

    Creator:
    Wangelin, James Richard
    Abstract:
    In October 1977, a study was undertaken to determine the role of bovine adenovirus type 3 in enzootic pneumonia of calves, and the efficacy of using a vaccine for prevention of disease. Bovine adenovirus type 3 was isolated from the herd under study in the previous year. Calves in the...

  • Antigenic comparison of five bovine adenovirus type 3 isolates using a fluorescent foci assay system

    Creator:
    Liauw, Hardi Kian-hong
    Abstract:
    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...

  • Viral causes of pneumoenteritis in lambs in western Oregon

    Creator:
    Ullrich, Nancy Ann
    Abstract:
    One hundred and fourty-one lambs showing signs of pneumonia and/or enteritis from four different flocks in western Oregon were sampled for virus isolation. Two ovine adenoviruses, antigenically distinct from each other and from bovine adenoviruses, were isolated from the nasal mucosa and feces of two lambs. The lambs were showing...

  • Development and optimization of a kinetics-based enzyme-linked immunosorbent assay (KELA) for serologic diagnosis of bovine respiratory syncytial virus infection

    Creator:
    Chaloupka, Kim A.
    Abstract:
    A kinetics-based enzyme-linked immunosorbent assay (KELA) for detection of serum IgG antibody against bovine respiratory syncytial virus (BRSV) was developed and optimized. Optimization factors tested included brand of microELISA plate, length of incubation periods at various temperatures, type of conjugate, purified versus precipitated antigen preparations, type of dilution buffer as...

  • Development of an enzyme-linked immunosorbent assay for the serologic diagnosis of bovine adenovirus type 3

    Creator:
    Whipple, Margaret Jo
    Abstract:
    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...

  • Serologic survey of llamas in Oregon for antibodies to viral diseases of livestock

    Creator:
    Picton, Rebecca Anne
    Abstract:
    Serums from 270 llamas representing 21 farms throughout Oregon were obtained and assayed for antibody levels against viruses of livestock. These viral diseases included: bovine viral diarrhea (BVD), bovine herpesvirus 1 (BHV-1), parainfluenza-3 (PI-3), bovine respiratory syncytial virus (BRSV), bovine adenovirus species 3 (BA3), equine herpesvirus 1 (EHV-1), equine adenovirus...

  • Antigenic comparison of bovine, ovine, equine, and llama adenoviruses

    Creator:
    Yusuf, Irwandi
    Abstract:
    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...

    Babar, Shakeel
    Abstract:
    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...

  • Characterization of adenovirus isolated from sheep in Oregon

    Creator:
    Babar, Shakeel
    Abstract:
    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...
