Genome sequencing and assembly of Streptococcus dysgalactiae isolated from channel catfish
Streptococcus dysgalactiae is an emerging pathogen in cultured fish worldwide. Since this bacterium targets the reproductive organs (ovaries) of some fish species, brood stocks of channel catfish at a commercial catfish operation in the Mississippi delta region were sampled for presence of pathogen. Fingerlings that originated from the brood fish were also collected and sampled. Samples were plated on selective medium, classified by Lancefield grouping (Lancefield Group C Streptococcus), and further cultured for genome sequencing and assembly. The goals of this sequencing project are to identify potential virulence factors responsible for causing disease in catfish and improve therapeutic outcomes.
