Infection and Tumor Formation in Chickens By Avian Leukosis Virus
Lymphoid leukosis in chickens is a disease which arises from the result of complicated interaction between avian leukosis virus (ALV) as a pathogenic organism and chicken as a host. This report is intended to outline our present knowledge about genetic resistance of chickens in lymphoid leukosis. The defense of host in infectious disease could be considered dividing it into two: one as a workin...
متن کاملResponse of white leghorn chickens of various B haplotypes to infection at hatch with subgroup J avian leukosis virus.
White leghorn chickens from seven 15.B congenic lines (genetically similar except for genes linked to the major histocompatibility complex [MHC] B haplotype) and two Line 0.B semicongenic lines were infected at hatch with strain ADOL Hc-1 of subgroup J avian leukosis virus (ALV-J). At 5, 8, 16, and 36 wk of age, chickens were tested for viremia, serum-neutralizing antibody, and cloacal shedding...
متن کاملResponse of white leghorn chickens of various genetic lines to infection with avian leukosis virus subgroup J.
In Experiment 1, chickens from various white leghorn experimental lines were inoculated with strain ADOL-Hcl of subgroup J avian leukosis virus (ALV-J) either as embryos or at 1 day of age. At various ages, chickens were tested for ALV-J induced viremia, antibody, and packed cell volume (PCV). Also, at 4 and 10 wk of age, bursal tissues were examined for avian leukosis virus (ALV)-induced prene...
متن کاملA 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....
متن کاملMyxosarcomas associated with avian leukosis virus subgroup A infection in fancy breed chickens.
Formalin-fixed suspect tumors were submitted to the Poultry Diagnostic and Research Center at the University of Georgia (Athens, GA) for diagnosis. Samples were from fancy breed chickens with a history of increased tumor prevalence in both hens and roosters. Microscopically, in all the samples, there were neoplastic proliferations of spindle-shaped cells. The matrix surrounding tumor cells stai...
