lüll Disease transmission by cannibalism: rare event or common occurrence?Rudolf VH; Antonovics JProc Biol Sci 2007[May]; 274 (1614): 1205-10Cannibalism has been documented as a possible disease transmission route in several species, including humans. However, the dynamics resulting from this type of disease transmission are not well understood. Using a theoretical model, we explore how cannibalism (i.e. killing and consumption of dead conspecifics) and intraspecific necrophagy (i.e. consumption of dead conspecifics) affect host-pathogen dynamics. We show that group cannibalism, i.e. shared consumption of victims, is a necessary condition for disease spread by cannibalism in the absence of alternative transmission modes. Thus, endemic diseases transmitted predominantly by cannibalism are likely to be rare, except in social organisms that share conspecific prey. These results are consistent with a review of the literature showing that diseases transmitted by cannibalism are infrequent in animals, even though both cannibalism and trophic transmission are very common.|*Cannibalism[MESH]|*Disease Transmission, Infectious[MESH]|*Models, Biological[MESH]|*Social Behavior[MESH]|Animals[MESH]|Computer Simulation[MESH]|Humans[MESH] |
