Expression of tumour phenotypes, hatchability and liver tumour mortality in two routes of inoculation in fowl.

Abstract excerpt

A total of 350 and 200 eleven-day-olc embryos (pooled breeds) of twelve hatch replicates were inoculated with pseudotype of Bryan high titre, RSV(RAV-49) of subgroup C viz CAM (chorioallantoic membrane) and YS (yolk sac) route, respectively. An increase in hatchability (about 16%) and decrease in the incidence of CAM(+) [71%] and LT(+) [47%] phenotypes was noticed when inoculation was done via YS route as...
