Detection of Agglutinins in Chickens Infected with JM Leukosis Virus

Agglutinins in chickens infected with JM leukosis virus.

Hemagglutinins for sheep red blood cells were detected in sera from JM virus-infected single-comb White Leghorn (susceptible S line) chickens. The agglutinins were not sedimented at 97,000 x g and were not affected by freezing and thawing, possibly indicating a soluble hemagglutinating factor. Agglutination titers were read in a relatively short period, after 4 hr of incubation at 4 C. The usef...

Initial lesions in chickens infected with JM strain of Marek's disease virus.

Aberrant expression of liver microRNA in chickens infected with subgroup J avian leukosis virus.

Subgroup J avian leukosis virus (ALV-J) is an oncogenic retrovirus primarily causing myeloid leukosis (ML) in broilers. Although ALV is well under control in a few countries including the USA, poultry industry in many parts of the world continues suffering from serious economic loss due to sporadic or widespread ALV infection, especially ALV-J infection. ALV-J infection of chickens is reportedl...

A novel subgroup of exogenous avian leukosis virus in chickens.

An avian leukosis virus with a wide host range belonging to a new subgroup for chickens was isolated from meat-type chicken lines. The virus, of which HPRS-103 strain is the prototype, was of low oncogenicity in chickens but appeared to behave like an exogenous leukosis virus. Neutralizing antibodies to the virus were found in three of five meat-type chicken lines, but not in seven layer lines....

Detection of avian influenza virus of H9 subtype in the feces of experimentally infected chickens by RT–PCR

  Avian Influenza (AI) is a viral respiratory disease of domestic and wild birds. In the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. Cloacal swabs collected from chickens experimentally infected with H9 subtype AI virus, used in a reverse transcription-polymerase chain reaction (RT-PCR) assay for detection of AI. In infected animals, ...
