Invasion of the French Paleolithic painted cave of Lascaux by members of the<i>Fusarium solani</i>species complex

Abstract

A major fungal invasion was discovered in the prehistoric painted cave of Lascaux in France in Sep 2001. At least three species of the Fusarium solani complex were isolated and identified with a portion of the translation elongation factor 1α gene (EF-1α), a portion of the nuclear large subunit rDNA (LSU) and nuclear ribosomal intergenic spacer region (ITS). This study represents the first time that Fusarium species have been reported from a cave containing prehistoric paintings. Significant interspecific molecular variability was observed, suggesting that there might have been repeated introduction of the species, possibly carried by water from soils above the cave.
