Retraction

The publisher hereby retracts the article titled “Alloreactivity and Association of Human Natural Killer Cells with the Major Histocompatibility Complex” by E. Mavoungou, A. Sall, V. Poaty-Mavoungou, F. S. Toure, P. Yaba, A. Delicat, and J. Lansoud-Soukate (Clin. Diagn. Lab. Immunol. 6:254–259, 1999). An investigation by the American Society for Microbiology Publications Board has determined that the paper was plagiarized from an earlier publication (“Human Natural Killer NK Alloreactivity and Its Association with the Major Histocompatibility Complex: Ancestral Haplotypes Encode Particular NK-Defined Haplotypes” by F. T. Christiansen, C. S. Witt, E. Ciccone, D. Townend, D. Pende, D. Viale, L. J. Abraham, R. L. Dawkins, and L. Moretta, J. Exp. Med. 178:1033–1039, 1993). The paper therefore is being retracted by ASM, as it represents a clear violation of ASM’s ethical standards.
