Summary of the simplest Generalized Linear Models for the pathogens found on the 18 livestock farms in central Argentina from 2008 to 2011 at the three studied levels.

At the small mammal community level, explaining the occurrence of each pathogen taking into account all the individuals captured on each farm and trapping session; at the population level, explaining the occurrence and prevalence of each pathogen in R. norvegicus populations taking into account only R. norvegicus individuals on each farm and trapping session; and at the individual level, explaining infection of each pathogen in R. norvegicus individuals. SM AB: small mammal abundance; PP and PP6: accumulated monthly precipitation and accumulated precipitation in the last six months, respectively; Type: type of productive system (dairy or pig farm); Temp: monthly mean temperature (°C); Rn: R. norvegicus; d.f.: residual degrees of freedom; % dev: percentage of deviance explained by the model; K: Kappa index; Sens: sensitivity, Spec: specificity; PCC: proportion of correct classifications.
