Abstract:
A total of 34 clinical isolates and 7 type strains of Veillonella spp. were tested for their ability to fluoresce on various culture media. Fluorescence was medium dependent and varied among the species. Scanning absorption spectrophotometry of culture extracts showed that the absorption spectrum of the fluorescent pigment is typical of a metal-free porphyrin.
