Transcriptome analysis unveils survival strategies of Streptococcus parauberis against fish serum.
Streptococcus parauberis is an important bacterial fish pathogen that causes streptococcosis in a variety of fish species including the olive flounder. Despite its importance in the aquaculture industry, little is known about the survival strategy of S. parauberis in the host. Therefore, the objecti...
