ABSTRACT

Eleven-day-old embryos of IWJ, IWG and IWC lines were inoculated with subgroup A and C Rous sarcoma virus (RSV) separately, via the chorioallantoic membrane (CAM) route. The infected embryos were hatched for collection of data on liver tumour (LT) deaths. The survival time was comparatively longer in IWJ line than that of IWC line, irrespective of virus subgroup infection. The mean days of survival was longer in the low pock count range (PCR) than in high PCR regardless of lines and virus subgroups. For subgroup A infection, the distance of mean days of survival was 8.31 days, in the range of 13.50 to 5.19 days with a median of 9.35 days; while for subgroup C infection 6.33 days, in the range of 12.81 to 6.48 days with a median of 6.65 days. However, once the pock count exceeded 1.40 log in the embryonic CAM, the chicks hatched from these eggs regardless of lines died of LT very fast within one week for both subgroups, A and C infection. Further analysis of data taking line, sex and PCR provided strong evidence that except the PCR factor, the other two factors did not influence the survival potential of LT(+) chicks. The interaction effect was not significant either, indicating the specificity of LT death as dictated only by PCR factor
