show Abstracthide AbstractIn this study, we quantified genome-wide single nucleotide polymorphisms among 73 B. anthracis isolates derived from 33 livestock carcasses sampled over one year (2016-2017) throughout the Ngorongoro Conservation Area in northern Tanzania, an area hyperendemic for anthrax. Diversity was investigated at various spatial scales: throughout the Conservation Area, between cases occurring in close spatio-temporal proximity, and within individual livestock carcasses.
