Sammanfattning

Streptococcus agalactiae is a contagious pathogen in bovine mastitis. It is also one of the leading causes to neonatal pneumonia, sepsis and meningitis in Europe and North America. Although extracellular bacterial proteins that interact with host structures are putative vaccine components, so far only a few receptins have been identified and characterised from this organism. The aim of the present study was to identify fibrinogen-binding receptins from a shotgun phage display library constructed from the bovine type strain CCUG 4208. A novel extracellular receptin was identified after selecting the library against bovine fibrinogen. This protein is a member of a family of at least three proteins that share the fibrinogen-binding region as well as the N-terminal signal sequence, whereas the intervening region varies in size and has almost no sequence similarity. Proteins of this family are present also in human isolates of S. agalactiae, although binding to human fibrinogen has not been detected. (C) 2003 Elsevier B.V. All rights reserved
