[Morphological changes of brain choroid plexuses and ventricle induced by enterovirus infections in monkeys]
Abstract:
The morphological study of monkeys' brains, infected by the Bulgaria strain of enterovirus-71 (EV71), revealed specific for truncus cerebral encephalomyelitis, reactive and destructive changes in different areas of the brainstem and the spinal cord. For the first time viral cytopathology and destruction of choroid plexuses as an important secretory organ of the central nervous system, and ventricle of the brain infected by enterovirus have been studied. The specificity of this infection and the participation of neuroepithelium in reproduction of EV71 have been confirmed by identification of EV71 antigen in the choroid plexuses. According to our data the choroid plexuses take important part in the pathogenesis of EV71 encephalomyelitis. Pathologic changes have been found out in the barriers of CNS. The morphological changes in the brain of monkeys and cotton rats were similar; therefore the last one could be a useful model for different investigations.
