Myopathy and Encephalopathy in Chick Embryos Experimentally Infected with Akabane Virusg

Experimentally induced Chiari-like malformation with myeloschisis in chick embryos.

Though several pathogenetic theories concerning the frequent association of Chiari malformation and hydrocephalus with myeloschisis have been suggested, none of them explains all the aspects of the disorder. To investigate whether myeloschisis is the direct cause of Chiari malformation and hydrocephalus or these conditions are the results of another basic event, we observed the morphological ch...

Ultrastructural findings in pigs experimentally infected with bovine spongiform encephalopathy agent.

We report here an electron microscopic study of selected nervous system tissues from pigs infected experimentally with the agent of bovine spongiform encephalopathy (BSE). Generally, the ultrastructural neuropathology of BSE-affected pig brain resembled that of BSE-affected cattle brain. Spongiform change, in the form of membrane-bound vacuoles separated by septae into secondary chambers, domin...

Evaluation of antioxidant status and oxidative stress in sheep experimentally infected with Anaplasma ovis

Anaplasma ovis infections can cause severe anemia in the acute phase of the disease. In order to investigate the alterations of erythrocyte protective antioxidant mechanisms associated with anemia in sheep experimentally infected with A. ovis, 100 ml heparinized blood was collected from splenectomised sheep that showed 6% A. ovis parasitemia. Inoculums of 20 ml blood were administered intraveno...
