M. Fadel et P. Courtois, Inhibitory effect of lactoperoxidase-generated hypothiocyanite upon black pigmented anaerobe growth, INT J MOL M, 8(1), 2001, pp. 59-62
This study aimed to evaluate the in vitro effect of lactoperoxidase with or
without its substrates (hydrogen peroxide, thiocyanate) on the growth of 4
different black pigmented anaerobe (BPA) strains associated with the devel
opment and progress of periodontal diseases: Porphyromonas gingivalis ATCC
33277, Prevotella intermedia NCTC 9336, Prevotella loescheii ATCC 15930, an
d Prevotella melaninogenica NCTC 9338. A 5-min lactoperoxidase-generated OS
CN--HOSCN incubation at pH 6.0, 7.0 or 8.0 resulted in a decrease of the gr
owth rate (tested by turbidimetry in liquid cultures) of the 4 BPA strains,
whilst lactoperoxidase alone actually promoted bacterial growth.
