Bovine lymphosarcoma virus commonly affects multiple organs; which combination includes the heart and reproductive organs among the frequent sites?

• A. Liver, Spleen, Pancreas, Brain
• B. Right atrium, uterus, abomasum, kidney
• C. Lungs, Heart, Kidneys, Skin
• D. Spinal Cord, Muscle, Bone, Lymph Nodes

Answer: (B)

Bovine lymphosarcoma from bovine leukemia virus tends to produce tumors in several organs, with the heart (often the right atrium) and the uterus being common sites, along with others like the abomasum and kidney. The option that includes a heart structure (right atrium) and a reproductive organ (uterus) reflects this typical distribution, making it the best choice. Other sets either omit the heart or the reproductive organ, or list organs not as commonly involved together in this disease pattern.
