Detection of a novel fimbrial structure on the surface of Salmonella enteritidis by using a monoclonal antibody.

摘要: A fimbrialike structure expressed on the surface of Salmonella enteritidis was identified by using a monoclonal antibody (69/25) produced against intact S. cells. Fimbriae were less than 5 nm in diameter and carried protein consisting subunits with molecular weight 14,300. No hemagglutinating activity associated fimbriae detected. An epitope fimbrial antigen 69/25 all 58 strains, 12 36 dublin single strain moscow examined. None 169 other isolates tested from 17 salmonella serogroups this epitope.
