Overview of micro-organisms reported in selected publications. The columns depict; the micro-organisms reported in studies, animals involved carrying or infected with the micro-organism, transmission of a disease; excretion site of the micro-organism to uptake site, transmission pathway; mode of transmission of the micro-organism, number of identified studies, reference number. Transmission pathways as defined in indicated references.
