    ZEBRA genes:Z EBV replication activator (ZEBRA) as lytic cycle markers.ZEBRA is one of the immediate early genes of EBV.it is considered to be expressed in the initial stage of the lytic cycle, before the viral particles have been dispersed.

    Zebra sign:. Hemorrhage is often characterized by a typical, streaky bleeding pattern due to blood spreading in the cerebellar sulci. this zebra-pattern hemorrhage seems to be typical in a postoperative loss of CSF.

    Zebra tumor = acoustic neuroma

    Zebra bodies - lipid inclusions with concentric lamellar structure with alternating light and dark-staining bands in neuronal sells .... niemanpicks
