Transmission of avian leukosis virus, subgroup J (ALV-J), from donor chickens inoculated as embryos to simulate congenital infection to uninfected hatchmates was studied in two strains of commercial broiler breeder chickens. Chicks of two commercial

Marek's disease virus, a herpesvirus, and avian leukosis virus, subgroup J, a retrovirus, are oncogenic viruses of poultry. Both viruses may infect the same flock, the same bird and the same cell. In a double-infected cell, the retroviral DNA can int

Profiles of infection with avian leukosis virus subgroup J (ALV-J) and factors that predict virus transmission to progeny were studied. Eggs from an infected broiler breeder flock were hatched at the laboratory. The flock was reared in a floor pen, t

We have developed a quantitative-competitive (QC) polymerase chain reaction (PCR) for the detection of Marek's disease virus (MDV) DNA. The assay utilizes a competitor DNA that differs from the viral DNA of interest by having a small insertion. The c

Glycoprotein D (gD) and its homologues are essential for many alphaherpesvirus life cycles. A gene encoding a homologue of gD was recently found in the Marek's disease virus (MDV) genome. Interestingly, gD-negative MDV mutants apparently replicate un

A chronological study of central nervous system disorders induced by Marek's disease virus (MDV) has been conducted. Neurologic clinical signs were recorded daily for individual chickens of two genetic lines after inoculation of 13 serotype 1 MDV str

A novel syndrome was observed after inoculation of 3-wk-old chickens with highly virulent Marek's disease virus (MDV) strains. This syndrome was characterized by the acute onset of neurologic signs including flaccid paralysis of neck and limbs 9-10 d

Hemorrhagic enteritis (HE) is an economically important disease of turkeys caused by a type II aviadenovirus, hemorrhagic enteritis virus (HEV). The vaccines currently available to the commercial poultry producer are highly effective in preventing di

Marek's disease (MD) is a lymphoproliferative disease of chickens that costs the poultry industry approximately $1 billion annually. Genetic resistance to MD is gaining increased attention to augment vaccinal control as disease outbreaks occur more f
