Lymphoma incidences (A) and dissemination patterns (B) in chickens infected with parental, vTR mutant, and vTR revertant viruses. Lymphoma incidences are given as the percentage of birds having lymphomatous lesions. Dissemination patterns are shown as the percentages of birds that failed to develop lymphoma (0) or in which less than or more than two sites of lymphoma manifestation were observed. The decreased lymphoma incidence detected in groups infected with vCR1-2−/− relative to groups infected with vRB-1B, vCR1-2+/−, vCR1-2−/−R1, or vCR1-2−/−R2 were statistically significant (*) as follows: vCR1-2−/− versus vRB-1B, P = 0.0361; vCR1-2−/− versus vCR1-2+/−, P = 0.0453; vCR1-2−/− versus vCR1-2−/−R1, P = 0.0361; vCR1-2−/− versus CR1-2−/−R1, P = 0.0094.
