Figure 5. Most likely number of Plasmodium knowlesi parasite subpopulation haplotype clusters (K) in Malaysian Borneo (gray) and Peninsular Malaysia (white). A) Type A small subunit ribosomal 18S RNA (K = 2, ΔK = 121.79), including comparison of K and ΔK; B) cytochrome oxidase subunit I (K = 2, ΔK = 481.27), including comparison between K and ΔK. Relationships were determined by using Bayesian model–based STRUCTURE version 2.3.4 software (The Pritchard Laboratory, Stanford University, Stanford, CA, SUA). ΔK = mean (|L′′(K)|)/sd(L(K)). Vertical axes represent membership coefficient values.
