Abstract
At the request of the authors, with the consent of the Journal Editor and the Publisher, the following article has been retracted.
López-Medrano R, Guerra-Laso JM, López-Fidalgo E, et al. Plasma contributes to the antimicrobial activity of whole blood against Mycobacterium tuberculosis. Innate Immunity 2016; 22:7 557–566, DOI: 10.1177/1753425916663311.
The authors did not realise that the use of EDTA created errors in the paper. Although mycobacteria remain alive in the presence of EDTA, the formation of visible colonies is inhibited, which affected the enumeration of colony forming units for the quantification of the antimicrobial activity. Consequently, the absence of colonies was erroneously interpreted as mycobactericidal activity. Due to this error the article’s main finding about the antimycobacterial activity detected in plasma is incorrect.
