It is a good question.Currently, scientists have developed several molecular techniques, which help in identification of pathogenic microbes.One can study the molecular epidemiology of infectious diseases.We have uploaded several papers on recent techniques employed in diagnosis of zoonotic diseases,which are globally prevalent.
