Bioaccumulation of Pathogen Exposure in Top Predators

Area of Science:

• Ecology
• Wildlife Disease Ecology
• Conservation Biology

Background:

• Predator-prey relationships facilitate pathogen transmission.
• Prey-to-predator pathogen spillover can cause severe epizootics.
• Conservation of sensitive species is threatened by these spillover events.

Purpose of the Study:

• To examine mechanisms of pathogen exposure in predators from prey.
• To investigate factors influencing the frequency and outcomes of pathogen spillover.
• To highlight the role of predator-prey dynamics in disease ecology.

Main Methods:

• Case study analysis using felids as apex predators.
• Review of existing literature on pathogen spillover events.
• Examination of virulent and clinically silent infections in predators.

Main Results:

• Apex predators can acquire both severe and asymptomatic infections from prey.
• Predator exposure to prey pathogens is influenced by interaction dynamics.
• Specific examples demonstrate pathogen transfer from prey to predators.

Conclusions:

• Predator-prey dynamics are critical for understanding pathogen spillover.
• Further research and modeling should incorporate these interactions.
• This approach will advance knowledge on pathogen bioaccumulation in wildlife.
