However, the probability of these events lining up is likely to be much higher within the human or domestic animal microbiota, as selection pressures, commensals and pathogens are more commonly encountered together, and there are no environmental transmission barriers that need to be overcome91. By contrast, wherever such transmission events become common, as is probably the case in many low- and middle income countries with inferior infrastructure for handling faecal waste (Box1), environmental transmission may have profound effects on the overall resistance situation95.
