We consider a Volovik's analogue model for the description of topological defects in a superfluid and we investigate the scattering of quasiparticles in this background. The analogue of the gravitational Aharonov-Bohm effect in this system is found. An analysis of this problem employing loop variables is considered and corroborates the existence of the Aharonov-Bohm effect in this system. The results presented here may be used to study the Aharonov-Bohm effect in superconductors.
