Abstract
The morphogenesis of duck enteritis virus (DEV) and distribution in vivo were observed by electron microscopy after ducks were infected experimentally with DEV virulent strain. The investigation showed that a few typical herpesvirus virions and nucleocapsids were first observed in the spleen, thymus, and bursa of Fabricius (BF), and many nucleocapsids, mature viruses, and viral inclusion bodies could be found in the nucleus and cytoplasm of infected liver, small intestine, spleen, thymus, and BF when the ducks died. Nucleocapsids assembled both in nucleus and cytoplasm and could be divided into four different types according to their structures. Typical herpesvirus, light particles (L-particles), and virions without tegument could be observed at the same time. With the replication, assembly, and maturation of the viruses, intracytoplasmic and intranuclear inclusion bodies, electron-density particles, microtubules, hollow tubes, and coated electron-density bodies were observed in infected cells. Resumen Estudios de microscopía electrónica sobre la morfogénesis del virus de la enteritis de los patos. Se estudiaron la morfogénesis y la distribución in vivo del virus de la enteritis de los patos mediante microscopía electrónica en patos infectados experimentalmente con una cepa virulenta del virus. La investigación mostró que algunos viriones y nucleocápsidos típicos de virus herpes se observaron inicialmente en el bazo, timo y bolsa de Fabricio (BF). También se observaron numerosos nucleocápsidos, partículas virales maduras y cuerpos de inclusión en el núcleo y citoplasma en células de hígado, intestino delgado, bazo, timo y BF de los patos muertos. Los nucleocápsidos observados tanto en el núcleo como en el citoplasma pudieron ser divididos en cuatro diferentes tipos de acuerdo con sus estructuras. Se pudieron observar al mismo tiempo partículas ligeras (partículas-L) típicas de herpesvirus y viriones sin tegumento. Con la replicación, ensamblaje y maduración de los virus, en las células infectada...This publication has 10 references indexed in Scilit:
