    RETRACTED: Melanin Produced by Bordetella parapertussis Confers a Survival Advantage to the Bacterium during Host Infection by Yukihiro Hiramatsu, Takashi Nishida, Dendi Krisna Nugraha, Fuminori Sugihara, Yasuhiko Horiguchi

    Published 2021-10-01
    “…Our results also indicate that the brown pigment produced by the bacterium is melanin, because HppD is involved in the biosynthesis of a type of melanin called pyomelanin, and homogentisic acid, the monomeric precursor of pyomelanin, was detected by high-performance liquid chromatography-mass spectrometry analyses. In an infection assay using macrophages, the hppD-deficient mutant was internalized by THP-1 macrophage-like cells, similar to the wild-type strain, but was less able to survive within the cells, indicating that melanin protects B. parapertussis from intracellular killing in macrophages. …”
