fragment from the genome of streptococcus suis and its clinical uses

摘要

The invention relates to the field of diagnosis of and vaccination against Streptococcal infections and to the detection of virulence markers of Streptococci. The invention provides a method for modulating virulence of a Streptococcus comprising modifying a genomic fragment of said Streptococcus wherein said genomic fragment comprises at least a functional part of a fragment identifiable by hybridisation in Streptococcus suis to a nucleic acid or fragment thereof as shown in figure 5.
