What viral disease causes the formation of lumps on the ears, nose, and paws in rabbits?

• A. Coccidiosis
• B. Myxomatosis
• C. VHD
• D. Fleas

Answer: (B)

Myxomatosis is a viral disease that primarily affects rabbits and is caused by the Myxoma virus. This disease leads to the development of distinctive lumps and swellings, particularly on the ears, nose, and paws of infected rabbits. The swelling is a result of the virus inducing a severe inflammatory response, which manifests as the characteristic lesions. In addition to the visible lumps, affected rabbits can also exhibit other symptoms, such as lethargy, fever, and discharge from the eyes and nose. Myxomatosis is highly impactful and can be fatal, particularly in domestic rabbits that lack immunity. Understanding this disease is essential for rabbit care, especially in regions where the virus is known to be prevalent. The other options, such as coccidiosis, viral hemorrhagic disease (VHD), and fleas, do not present the same symptoms associated with myxomatosis. Coccidiosis is caused by a protozoan parasite and primarily affects the digestive system of rabbits. VHD is also viral but affects the liver and is characterized by sudden death rather than external lumps. Fleas, while a common external parasite associated with discomfort, do not cause the specific lesions linked with myxomatosis. This context highlights
