INTRODUCTION Identifying bacteria species is essential in both the clinical and research field. Many times, diagnosis and treatments highly rely on correctly pin pointing the pathogen present is a sample. On the other hand, quality control in the lab of food and other products also relies on bacteria characterization (Carson, 76).
