This article corrects:

  1. Contemporary cryptic sexuality in Trypanosoma cruzi Volume 21, Issue 17, 4216–4226, Article first published online: 9 July 2012

We wish to bring attention to the following correction to Ramirez et al. (2012). Fig. 2 contains two mislabelled population clusters. As such, there are two clusters labelled seven and two clusters labelled six. In fact, the pale green cluster with red border should read cluster three, not six. The pale blue cluster should read cluster four, not seven. This error was typographical and does not influence any of the results or conclusions of our work. A corrected version of Fig. 2 is shown here.

Figure 2.

Widespread mitochondrial introgression among 100 Colombian TcI clones. Left – Multidimensional scaling plot is based on a discriminant analysis of principal components for 13 clusters defined via K-means clustering (109 iterations, Bayesian information criterion minimum reached at = 13) across 24 nuclear microsatellite markers. Twenty-seven principal components were retained, constituting 80% of the total variation present. Clusters are defined by distinct colours and inertia ellipses, dots represent individual clones. Right – Rooted maximum composite likelihood tree constructed using neighbour joining under a Tamura-3 parameter model derived from 10 mtDNA gene fragments. Bootstraps indicate instability across 1000 pseudoreplicates. Coloured polygons at branch tips indicate nuclear cluster identity. Cluster 6 (green, black border) corresponds to TcIDOM. Red stars indicate clear instances of maxicircle introgression between genetically distinct nuclear clades. Isolate marked ‘H’ represents a mosaic hybrid (SEVcl11) maxicircle, confirmed via allele specific PCR (Fig. S3, Supporting information), and derived from parents labelled ‘P1’ and ‘P2’.
