Abstract
It has been clarified that pathogens bind to glycosphingolipid (GSL) receptors in mammals, but there have been very few reports on pathogen-binding GSLs in fish. Vibrios are facultative anaerobic bacteria ubiquitous in marine and brackish environments. They are members of the normal intestinal microflora of healthy fish, but some species can cause a disease called vibriosis in fish and shellfish when the hosts are physiologically or immunologically weakened. The adherence of vibrios to host intestinal tracts is a significant event not only for survival and growth but also in terms of pathogenicity. We show in this mini-review that sialic acid-containing GSLs (gangliosides), GM4 and GM3, are receptors to which vibrios adhere to epithelial cells in the intestinal tract of fish. We also describe the enzymes responsible for synthesizing these Vibrio-binding gangliosides in fish.
