Figure 1From: Proof of concept of a method that assesses the spread of microbial infections with spatially explicit and non-spatially explicit dataSpatial context. Spatial location of: investigated farms and road network (a), farm size (b), dairy cows/county (c), and (farms/county d). The Ryan-Joiner (RJ) test indicated that the (log) number of isolates/EP for the 24 microbial genotypes (EP) found in ≥ 2 isolates (interfarm EP ratio) differed significantly (P < 0.05) from a normal distribution (diagonal line, e).Back to article page
