Inclusion Body Disease (IBD) is a disorder characterized by intracytoplasmic corpuscles in different tissues, mainly in the CNS, wich is responsible for the major neurological signs attributable to this disease. It affects Boas and Phytons in captivity and have been a global concern due to the high morbidity and mortality. The diagnosis is made by visualization of corpuscles caused by a modified Arenaviruses. Salmonella sp. belongs to microflora of cold and warm-blooded animals; it is an opportunistic pathogen that can causes gastrointestinal or septic disorders. In reptiles, Salmonella sp. is the bacteria most frequently quotes in spondylitis and osteomyelitis. This article describes a boa constrictor (Boa constrictor constrictor) that had restriction of movement and multiple granulomas in the dorsal vertebrae, the shadowgraph showed up fractured regions. After months of treatment without clinical improvement and the emergence of new injuries, the animal started to get prostrate, anorexic, cachectic and developed opisthotonos. It was opted for euthanasia. At necropsy it was found in multiple spots swelling of the dorsal vertebrae that ranging from mild to moderate. At the cutting vertebrae it was visible deformed and showed focal caseous content near the spinal cord, this was collected for microbiology where it was identified Salmonella sp. At microscopic evaluation the vertebrae had one to multifocal moderate inflammatory infiltrate of macrophages and heterophils. Some areas had lots of granulomas with central calcification and numerous giant cells. Other vertebras showed areas of osteomalácea and fibrosis. Rare focus had vertebral body fracture and spinal cord compression with mild infiltration entering the spinal cord canal. In the lung, especially in the bronchial epithelium, sometimes even within lymphocytes in bronchial-associated lymphoid tissue, in the intestine, liver, gall bladder, kidney and brain were found various structures of eosinophilic intracytoplasmic rounded ranging between 1 and 10 micrometers. These structures accompanied or not mononuclear inflammation. These findings are consistent with IBD and spondylitis due to salmonellosis. The IBD is a common disease in captive snakes, of world importance, is probably underdiagnosed in Brazil. This disease causes immunosuppression favoring the development of other affections, and is typically associated with other diseases such as spondylitis found in the case. |
