| 中文摘要 | Moribund specimens of the oyster, Crassostrea ariakensis Gould, aged 2-3 years were collected from Hailing Bay in Yangxi County of Guangdong Province from February to May and November to December in the years 2001, 2002, and 2003. A massive infection by an obligate intracellular prokaryote, specifically a rickettsia-like organism (RLO), was found. Here we report investigations of this RLO in the tissues of the oyster C. ariakensis Gould and describe the histology, ultrastructure, and morphogenesis of this pathogen in C ariakensis Gould. Light microscopic observations of stained tissues revealed cytoplasmic inclusion bodies typical of prokaryote infection in about 87% (26/30) of the oysters. Most inclusions were observed in epithelial cells and connective tissues of the gill, mantle, and digestive gland of most of the infected oysters. The shape, size, and color of inclusions from different tissues were polymorphic. Electron microscopic examination of digestive gland, gill, and mantle tissues showed that the RLOs were intracytoplasmic. RLOs were often round, dumb-bell-shaped (undergoing binary fission), or occasionally rod-shaped and ranged from approximately 0.58 to 1.20 mum in size. The organisms exhibited an ultrastructure characteristic of prokaryotic bacteria-like cells. including a trilaminar cell wall, electron-dense periplasmic ribosome zone, and a DNA nucleoid. Reproductive stages, including transverse binary fission, were observed by TEM. These stages were frequently observed within membrane-bound cytoplasmic vacuoles. Hexagonal phage-like particles in the cytoplasm of RLOs were also observed. (C) 2004 Elsevier Inc. All rights reserved. |
