AB  - Red fluorophores synthesized by oral bacteria are important for fluorescence-based diagnosis and treatment because they are used as markers for bacterially infected tissue, mature plaque, or calculus. A range of porphyrins have been identified as the source of this fluorescence in carious tissue. It is not clear which of these porphyrins are produced by individual oral bacteria or whether this ability depends on other factors. This study examined and compared the fluorescence spectra produced by selected cultured oral bacteria when grown on agars containing different nutrients with spectra for protoporphyrin IX, Zn-protoporphyrin IX, haematoporphyrin, and haematin. Actinomyces israelii (Deutsche Sammlung von Mikroorganismen [DSM], 43320), Actinomyces naeslundii (DSM 43013), Fusobacterium nucleatum (DSM, 20482), Lactobacillus casei (DSM, 20011), Prevotella intermedia (DSM, 20706), Streptococcus mutans (DSM, 20523), Streptococcus oralis (DSM, 20627), Streptococcus salivarius (DSM, 20560) and Streptococcus sobrinus (DSM, 20742) were rehydrated and grown anaerobically on caso, caso blood (containing 5
