Fig. 3From: Use of whole-genome sequencing to distinguish relapse from reinfection in a completed tuberculosis clinical trialIdentification of mixed infection. a Counts of genome sites which were called as a reference base but showed a significant proportion of sequence reads also supporting a variant base call (035-1); b the equivalent plot for an isolate with no mixed infection (035-2). The presence of a second peak in a is suggestive of a mixture with a minority genotypeBack to article page
