直到 20 世纪 70 年代，鱼类中稳定的本土微生物群的作用甚至存在才被接受。在过去的十年中，我们对鱼肠道中细菌的粘附和易位的了解有所增加，电子显微镜对这方面的知识做出了重大贡献。本综述总结了有关肠道相关细菌和鱼类胃肠道细菌易位的可用信息。在对各种淡水鱼和咸水鱼的几项研究中，通过使用透射电子显微镜和/或扫描电子显微镜证实了肠腔中的细菌和上皮相关细菌。其中一些研究表明，细菌细胞通过幼鱼和成鱼胃肠道内吞作用发生易位，并摄取完整的细菌抗原。消化道中细菌的内吞作用高度相关，因为胃肠道是病原体的潜在进入口。 (C) 2003 年，Elsevier B.V. 出版
The role, and even the existence, of stable indigenous microbiota in fish was not accepted until the 1970s. In the last decade, our understanding of adhesion and translocation of bacteria in the fish gut has increased, and electron microscopy has contributed significantly to this knowledge. This review summarises the information available on gut-associated bacteria and on the translocation of bacteria in fish gastrointestinal tract.In several studies on various fresh- and saltwater fish, bacteria in the intestinal lumen and epithelium-associated bacteria have been demonstrated by using transmission electron microscopy and/or scanning electron microscopy. Some of these studies have demonstrated translocation of bacterial cells by endocytosis in the gastrointestinal tract of larvae and adult fish as well as uptake of intact bacterial antigens. Endocytosis of bacteria in the digestive tract is highly relevant as the gastrointestinal tract is a potential port of entry for pathogens. (C) 2003 Published by Elsevier B.V.
