We provide pathological, immunohistochemical and molecular evidence of cetacean morbillivirus (CeMV) infection in a live-stranded adult female killer whale (Orcinus orca), which stranded alive in Espírito Santo State, Brazil, in 2014. Although attempts were made to release the animal, it stranded again and died. The main pathological findings were ...

A 7-month-old male domestic ferret (Mustela putorius furo) was presented for evaluation of unilateral testicular enlargement. Microscopic examination of the left testicle revealed a neoplasm with differentiation along multiple cell lines (ectoderm, endoderm, mesoderm) including respiratory epithelium, bone and haired skin. A poorly differentiated e...

A Himalayan Rex guinea pig was presented with a history of nodular, partially ulcerated masses in the subcutis of the left shoulder. Histological examination revealed a garland-like to nodular, infiltrative neoplastic mass of the epidermis and hair follicle epithelium, which obscured the dermoepidermal junction. Neoplastic cells were immunopositive...

A 41-year-old female captive gorilla with progressive weight loss and hydrothorax of unknown origin was euthanized and submitted for necropsy. The ascending aorta showed intimal aortic thickenings, consistent with so called 'tree bark' changes. Microscopic examination revealed a non-infectious, necrotizing and granulomatous aortitis with no evidenc...

Lesions caused by trombiculid mite larvae ('chiggers') in birds have been inadequately described. A juvenile red-legged partridge (Alectoris rufa) presented with multifocal, crater-like lesions of necrotizing dermatitis, which often contained multiple orange mites. Microscopically, there was a nodular necrotizing and pyogranulomatous dermatitis wit...

A 3-year-old Quarter Horse mare presented with an approximate 1-month history of progressive weight loss, anorexia and lethargy that abruptly worsened 48 h before death. Post-mortem examination revealed free flocculent fluid and a large mass within the ventral abdomen that dorsally displaced the caecum and large intestine. An ovarian teratocarcinom...

Although canine pancreatic neuroendocrine neoplasms (PanNENs) have been proposed as a model for the counterpart human neoplasms, the type or grade of human PanNEN that they resemble is unclear. PanNENs in animals are classified as adenoma or carcinoma, whereas in humans they are classified as pancreatic neuroendocrine tumour (PanNET) if well-differ...

A two-year-old male African pygmy hedgehog (Atelerix albiventris) presented with lethargy and anorexia. Ultrasonographic and radiographic examinations revealed splenomegaly and pneumonia, respectively. Prominent leucocytosis, consisting mainly of large atypical eosinophils, was observed in a peripheral blood smear. Necropsy revealed a black scab on...

We describe a fatal kidney disease in green iguanas (Iguana iguana), associated with severe nephromegaly. Affected animals have enlarged kidneys, which fill the pelvic cavity, leading to compression of adjacent organs, obstipation and, ultimately, death. The pathological features of this disease have been poorly described and its aetiology is unkno...

Astroviruses (AstVs) are emerging, potentially zoonotic pathogens, associated with enteric and neurological signs in various animal species. In pigs, five lineages have been identified, porcine AstVs (PoAstVs) 1-5. We now report PoAstV5-associated atrophic enteritis in a colostrum-deprived (CD) pig and a similar disease in field cases of enteritis....
