Resumen

Dear Editor:
Avian leukosis virus (ALV) is the causal agent of the most common naturally occurring avian retroviral infections causing neoplastic disease and other production problems in chickens. There are six well-characterized chicken subgroups of ALV (A to E and J). Viruses of subgroups A, B and J occur as common pathogenic exogenous viruses in the field. ALV infections with subgroups A (ALV-A) and subgroups B (ALV-B) have had a significant impact in the commercial layer flocks, both are associated with lymphoid leukosis (B-cell lymphoma) producing mortality after sexual maturity and lowered egg production. Subgroups J (ALV-J) is associated with myeloid leukosis and other production problems in meat-type chickens.
