Resumen:
Species diversity has been proposed to decrease prevalence of disease in a wide variety of host?pathogen systems, in a phenomenon labeled the dilution efect. This phenomenon was irst proposed and tested for vector-borne diseases but was later extended to directly transmitted parasite systems such as hantavirus. Though there seems to be clear evidence for the dilution efect in some hantavirus/rodent systems, the generality of this hypothesis remains debated. In the present meta-analysis, we examined the evidence supporting the dilution efect for hantavirus/rodent systems in the Americas. General linear models employed on data from 56 ield studies identiied the abundance of the reservoir rodent species and its relative proportion in the community as the only relevant variables explaining the seroprevalence of antibodies against hantavirus in the reservoir. Thus, we found no clear support for the dilution efect hypothesis for hantavirus/rodent systems in the Americas.
