“Filariasis free India” is National Health Policy’s vision. Currently, India has undertaken Mass Drug Administration drive (MDA) to eliminate the filariasis infection. Taking this into account, the emergence of new Wuchereria bancrofti resistant strains against the current choice of drugs cannot be ruled out. In this study, we report the genetic diversity of Wuchereria bancrofti from four districts (Amravati, Nagpur, Chandrapur and Wardha) of Vidarbha, a region in the eastern part of Maharashtra state of India and considered a hot spot of filariasis infections. The RAPD profiles were generated for 21 populations using nine random RAPD primers. The RAPD-PCR based distance matrix shows maximum genetic distance of 0.425 between the parasites from Nagpur and Amravati region and minimum genetic distance of 0.210 between the parasites of Wardha and Nagpur.
