Two cases of congenital lipomatosis in calves.

Fetal tumours in domestic animals are considered rare. Congenital lipomatous changes have been sporadically reported in fetal, neonatal and young bovids. Their prognosis is often guarded compared with benign lipocytic tumours and depends on their location and degree of infiltration.

Hemorrhagic bowel syndrome in dairy cattle: Gross, histological, and microbiological characterization.

Hemorrhagic bowel syndrome (HBS) is a sporadic and fatal disease of predominantly lactating dairy cattle, characterized by segmental hemorrhage and luminal clot formation in the small intestine. Although, and have been associated with HBS, the pathogenesis and cause are currently unknown. In this study, 18 naturally occurring cases of HBS (7 necropsied immediately following euthanasia, 11 with 12-48 hour postmortem intervals) were investigated to characterize the pathology and the intestinal microbiome.

Intervertebral disc degeneration in warmblood horses: Histological and biochemical characterization.

Gross morphology of healthy and degenerated intervertebral discs (IVDs) is largely similar in horses as in dogs and humans. For further comparison, the biochemical composition and the histological and biochemical changes with age and degeneration were analyzed in 41 warmblood horses. From 33 horses, 139 discs and 2 fetal vertebral columns were evaluated and scored histologically.

Two novel porcine teschovirus strains as the causative agents of encephalomyelitis in the Netherlands.

Background: Porcine teschovirus (PTV) circulates among wild and domesticated pig populations without causing clinical disease, however neuroinvasive strains have caused high morbidity and mortality in the past. In recent years, several reports appeared with viral agents as a cause for neurologic signs in weanling and growing pigs among which PTV and new strains of PTV were described.

Case Presentation: On two unrelated pig farms in the Netherlands the weanling pig population showed a staggering gate, which developed progressively to paresis or paralysis of the hind legs with a morbidity up to 5%.
