As part of the infective process, Porphyromonas gingivalis must acquire heme which is
indispensable for life and enables the microorganism to survive and multiply at the infection …

The Gram-negative oral anaerobe Prevotella intermedia forms an iron (III) protoporphyrin IX
pigment from haemoglobin. The bacterium expresses a 90 kDa cysteine protease, InpA …

We observed hemolytic activity in culture supernatant of Prevotella oris. Results from growth-
phase experiments show that hemolysin production increased during the logarithmic growth …

Polyphosphate (polyP) has gained a wide interest in the food industry due to its potential as
a decontaminating agent. In this study, we examined the effect of sodium tripolyphosphate …

Hemolytic activity was evaluated in the putative periodontopathogens Prevotella intermedia
and Prevotella nigrescens. Whole cells of both species present weak hemolytic activity …

Prevotella intermedia is a periodontal pathogen that requires iron for its growth. Although
this organism has hemolytic activity, the precise nature of its hemolytic substances and their …
