An Enzyme-Linked Immunosorbent Assay for Detection of Antibodies to Avian Adenovirus and Avian Adenovirus-Associated Virus in Chickens

Avian Diseases, 1980
An enzyme-linked immunosorbent assay system (ELISA) was adapted for the detection of antibodies to avian adenovirus (AV) and avian adenovirus-associated virus (A-AV). Both before and after exposure, sera from chickens undergoing natural and experimental infections were assayed by ELISA, virus neutralization (VN), and immunodiffusion (ID) for antibody ...

Inhibition and Enhancement of Avian Adenovirus Plaque Production by Heavy and Light Avian Adenovirus-Associated Viral Particles

American Journal of Veterinary Research, 1979
SUMMARY The effect of heavy and light avian adenovirus-associated viral (a-av) particles on the replication of several adenovirus serotypes was studied in chicken embryo kidney cells. There was a significant decrease (P < 0.05) in the number and size of adenovirus-induced plaques at a-av multiplicities of infection greater than 40.

Gene Transfer to Avian Embryos with a Recombinant Adenovirus

Developmental Biology, 1994
Replication-defective adenoviral vectors are widely used for gene transfer into mammalian cells. We show here that these vectors are also useful for delivering genes to chick embryos. Cells of many tissues expressed Escherichia coli beta-galactosidase following infection in vitro or in ovo with a recombinant adenoviral vector carrying this reporter ...

Detection of Avian Adenovirus by Polymerase Chain Reaction

Avian Diseases, 1999
An avian adenovirus-specific polymerase chain reaction was developed. The origin of primers was from the DNA sequence data of the chicken embryo lethal orphan avian adenovirus virus genome. An avian adenovirus-specific 421-bp DNA product was amplified by these primers from group I of adenovirus containing 12 serotypes and serotypes of adenovirus from ...

Induction of Tumors in Hamsters with an Avian Adenovirus (CELO)

Science, 1965
When newborn hamsters were inoculated subcutaneously with chicken-embryo lethal orphan virus, tumors developed at the site of inoculation in 23 out of 69 hamsters within 88 to 195 days of inoculation. These tumors and tissue cultures, prepared from a primary tumor, were transplantable to newborn and weanling hamsters.

Hemagglutinating Properties of CELO, an Oncogenic Avian Adenovirus

Avian Diseases, 1975
Chicken-embryo-lethal-orphan (CELO) virus, Phelps strain, agglutinated erythrocytes at 37 C. The hemagglutinating activity, which is a function of complete and incomplete virus particles, was sensitive to heat but not to pH. The soluble components of the virus were similar in sedimentation characteristics to those obtained from human adenovirus type 1.

Infection of the chicken with an avian adenovirus and Mycoplasma gallisepticum

Journal of Comparative Pathology, 1976
Abstract Chickens were infected with an avian adenovirus and Mycoplasma gallisepticum by injection into the trachea or infra-orbital sinus, respectively, or by acrosol. The mild clinical symptoms produced by virus were slightly enhanced in the presence of mycoplasma, which alone produced negligible signs of infection.

The Oncogenic Potential of Eleven Avian Adenovirus Strains

Avian Diseases, 1997
Oncogenic potentials of 11 strains of avian adenovirus representing 10 serotypes were investigated in 22 litters of 1-day-old Syrian hamsters (Mesocricetus auratus). Hamsters were inoculated via two routes: subcutaneous dose of 0.12 ml and intracerebral dose of 0.02 ml.

The Avian Adenovirus Penton: Two Fibers and One Base

Journal of Molecular Biology, 1995
The penton capsomer of mammalian adenoviruses consists of a trimeric, long and thin fibre inserted into a pentameric base. The avian adenoviruses possess a penton which presents another symmetry mismatch: each pentameric base is associated with two fibres. Here we have studied the morphology of the penton of CELO virus, an avian adenovirus, and we have
