Abstract: The present paper deals with the parametric analysis of ratio-dependent predator-prey system in which a disease is spreading among the prey species only. We have analyzed the behavior of the system around each equilibrium. Threshold Ro is identified which determine when the disease dies out and when it is endemic. Our final conclusion is that introduction of infected prey species in the ratio-dependent predator-prey model may act as a biological control to prevent the population from extinction.
