Aim: To describe the genomic characteristics of seawater-borne hemolytic Shewanella algae and its resistance genes.
Materials & methods: Whole genome sequence of S. algae SYT3 was determined using llumina MiSeq platform. Multiple-database-based analysis was performed to identify the genetic background of its hemolytic activity and the antibiotic resistance genes.
Results: S. algae SYT3 possesses a homolog of the hly operon involved in the synthesis of hemolysin. We also identified candidate genes associated with resistance to β-lactam antibiotics (bla OXA-55) and fluoroquinolone (qnrA3).
Conclusion: The study provides an insight into the hemolytic activity of S. algae. Our findings also suggested S. algae as a potential reservoir of antimicrobial resistance determinants.
Keywords: beta-lactamase OXA-55; hemolysin; hemolytic activity.
