Correction: What Do Pneumocystis Organisms Tell Us about the Phylogeography of Their Hosts? The Case of the Woodmouse Apodemus sylvaticus in Continental Europe and Western Mediterranean Islands.

[This corrects the article DOI: 10.1371/journal.pone.0120839.].

Upon re-examination of the samples included in this study, the authors have established that Cal6 is Apodemus flavicollis and not Apodemus sylvaticus as originally reported [1].

The identification of the Apodemus mice samples was completed following the protocol described in Michaux et al. [2] based on the sequencing of a mitochondrial cytochrome b fragment. All samples included in this study have been checked using this method.

The sequence obtained from sample Cal6 is in accordance with Apodemus flavicollis. This single result does not affect the general conclusions of the article. A recent study showed that Apodemus flavicollis and Apodemus sylvaticus may harbor the same Pneumocystis type [3]. These Apodemus species are closely related ecologically and phylogenetically. They can be trapped together and also show a high level of sympatry. They are members of the same subgenus Sylvaemus [4]. Furthermore, this result could be also explained by the fact that the densities of A. flavicollis can be more important in these regions with regard to A. sylvaticus. This would favor the spill-over of Pneumocystis between the two Apodemus species in these areas. Such a spill-over, which can lead to host switch, was already observed in the study of Danesi et al. [3], which also supported a host-specificity of Pneumocystis at least at the genus level.

We are including with this Correction a table listing the Apodemus individuals with details on their identification (Table 1). The amplified sequence for Cal6 has been deposited in the European Nucleotide Archive under accession number: LT622178, http://www.ebi.ac.uk/ena/data/view/LT622178.

* Apodemus sylvaticus is the only Apodemus species found on Mediterranean islands [4]: Corsica, Menorca, Mallorca, Sicily, Porquerolles

Apodemus sylvaticus and Apodemus flavicollis can be found in sympatry in Py and Calabria [5], [4]
