What type of virus causes Myxomatosis?

• A. Calicivirus
• B. Poxvirus
• C. Papovirus
• D. Rotavirus

Answer: (B)

Myxomatosis is caused by the Myxoma virus, which belongs to the Poxvirus family. This virus specifically infects rabbits and is known for causing significant illness and mortality within rabbit populations. The characteristics of Poxviruses, including their structure and replicative strategies, make them adept at surviving in hosts and eliciting pronounced disease symptoms, which is evident in the severe manifestations of Myxomatosis. Other viruses mentioned, such as Calicivirus, Papovirus, and Rotavirus, are associated with different diseases and organisms. Calicivirus, for example, is known to cause viral hemorrhagic disease in rabbits, while Papoviruses and Rotaviruses are related to infections in other animal species. Understanding the specific family and type of virus responsible for Myxomatosis is crucial for effective management and prevention in affected rabbit populations.
