A rapid detection of avian oncovirus group-specific antigens in feather pulp by the enzyme-linked immunosorbent assay.

An ELISA procedure for the detection of avian sarcoma-leukosis gs antigen in feather pulp of adult birds is described. The test can be used for identifying gs+ and gs- chickens in leukosis-free populations. The titres of exogenous and endogenous virus-coded gs antigens overlap and the ELISA can be used only for a preliminary screening of unknown chicken populations.

[Analysis of the susceptibility of the Minor inbred chicken strain to Rous sarcoma virus infection].

The sensitivity and resistance of the Minor hen inbred line to two antigenic subgroups of the Rous sarcoma virus were determined by the method of the infection of chorioallantoic membranes. The Minor line is sensitive to infection with the virus of the antigenic B subgroup and, as demonstrated by the testing of the interline hybrids of F1 and B1 generations, the birds of the Minor line are dominant homozygotes of genotype bsbs. The testing with the virus of antigenic A subgroup revealed a heterogeneity of the inbred population as to sensitivity and resistance. A formula was derived for the determination of the frequency of the dominant allele as determining sensitivity.
