Phenotypic and Genotypic Heterogeneity among Cultivable Pathogen-Related Oral Spirochetes and Treponema vincentii

Volume 37, no. 11, p. 3676–3680, 1999. Synthetic medium OMIZ-P4 was incorrectly described as containing fructose instead of fucose, and glucuronic acid was incorrectly described as being in OMIZ-P4 medium as well as in OMIZ-W1 medium (C. Wyss, J. Clin. Microbiol. 30:2225-2229, 1992). These errors did not contribute to outcomes described in our article because pathogen-related oral spirochete (PROS) isolates from Dr. Wyss grew well in our version of OMIZ-P4 medium. Furthermore, we used our modified OMIZ-P4 medium to isolate additional and distinct PROS specimens, and we used modified OMIZ-P4 medium to grow several other Treponema species (G. Riviere et al., unpublished data).
