Figure 1From: Characterization of DNase activity and gene in Streptococcus suis and evidence for a role as virulence factorComparative analysis of the ssnA gene according to STs. Nucleic acid and predicted amino acid sequences of ssnA gene (from position 1108 to 1173) of S. suis belonging to ST1, ST25, and ST28 were compared in order to identify the origin of the loss of DNase activity in ST25.Back to article page
