Mitochondrial activities in human cultured skin fibroblasts contaminated by Mycoplasma hyorhinis.

Background: Mycoplasma contaminations are a recurrent problem in the use of cultured cells, including human cells, especially as it has been shown to impede cell cycle, triggering cell death under various conditions. More specific consequences on cell metabolism are poorly known.

Results: Here we report the lack of significant consequence of a heavy contamination by the frequently encountered mycoplasma strain, M.
