Erratum to: Malar J (2016) 15:89 DOI 10.1186/s12936‐016‐1137‐5 After publication of the original article [1], the authors found that there was an error in the first sentence of the ‘Conclusions’ section: “The combination of CPE with the artemisinins showed a synergistic effect both in vivo and in vitro against P. falciparum 3D7 and P. berghei NK-65, respectively.” Within this sentence, the appearance of ‘P. falciparum 3D7’ and ‘P. berghei NK-65’ should have been reversed. The sentence in the original article has been corrected to read as follows: “The combination of CPE with the artemisinins showed a synergistic effect both in vivo and in vitro against P. berghei NK-65 and P. falciparum 3D7, respectively.”
