Fibromatosis Virus of Rabbits (FVR) is a highly contagious viral disease that affects rabbits, characterized by the growth of fibrous tumors or fibromas on various parts of the rabbit's body. FVR is caused by a specific strain of the poxvirus, known as the fibroma virus, which belongs to the family Poxviridae.
The virus can infect rabbits of all ages and breeds, with cases reported worldwide. Transmission of FVR occurs through direct contact with infected animals, as well as through contaminated objects, such as bedding, cages, or equipment. The virus can also be transmitted through insect vectors, such as fleas or ticks.
Clinical signs of FVR typically include the appearance of firm, round, nodular masses, commonly referred to as fibromas or tumors, which can be observed on the skin, ears, face, neck, or genitals of the infected rabbit. These growths can vary in size and number, sometimes causing discomfort, pain, or lameness. In severe cases, fibromas may ulcerate or become infected.
Diagnosis of FVR is usually based on clinical signs and confirmed through laboratory tests, such as PCR (polymerase chain reaction) or histopathological examination. Treatment options for FVR are limited, as no specific antiviral therapy currently exists. Therefore, managing the disease primarily involves supportive care, wound management, and control of secondary bacterial infections.
Prevention of FVR mainly relies on strict biosecurity measures, such as quarantine of affected animals, disinfection of facilities, and implementing practices to minimize disease spread. Additionally, vaccination against FVR is available in some regions, providing a preventative measure against this viral infection in rabbits.
