“…For the characterization of bacteria and their virulence factors, polymerase chain reaction (PCR) and gene sequencing are widely used in the field of aquatic science (Rahman et al, ). The detection and analysis of virulence factors play an important role in the study of pathogenicity of any pathogen, as these factors act in a coordinated manner in disease progression (Foysal, Rahman, & Prodhan, ; Oliveira, Gouveia, & Costa, ). Homology modelling is another common method for the analysis of protein structure and function on the basis of closest homolog or template.…”
