ABSTRACT
Objective:
To study the effects of ureolysis on the proliferation and acid-resistance of Actinomyces naeslundii.Methods:
The growth of Actinomyces naeslundii cultured in different nitrogen sources were measured, and the acid-resistant ability of Actinomyces naeslundii cultured in acid condition with different urea concentration was compared.Results:
In contrast with other nitrogen sources,Actinomyces naeslundii could be cultured by urea and higher final A value of the bacteria was obtained;at the range of pH=4.0-7.0, ureolysis could increase the survival of Actinomyces naeslundii from acid killing to some extend, but at pH=3.0, ureolysis could not protect Actinomyces naeslundii anymore.Conclusion:
Ureolysis may stimulate the growth of A. naeslundii and increase the acid-resistant ability of Actinomyces naeslundii.
