Research led by George Hajishengallis of Penn Dental sheds light on an aging-related condition that drives inflammation in older populations.

Bacteria in Gums Use Growth Molecules from Neighbors to Survive by Angela Mohan on  January 6, 2021 at 12:28 PM Veillonella parvula bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. P. gingivalis borrows growth molecules from V. parvula, a common yet harmless bacteria in the mouth whose growth is not population dependent. In a healthy mouth, P. gingivalis makes up a miniscule amount of the bacteria in the oral microbiome and cannot replicate...

Researchers test the effects of growth molecules exuded by oral bacteria The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, maybe too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new University at Buffalo-led study. The research sought to understand how P. gingivalis colonizes the mouth. The pathogen is unable to produce its own growth molecules until it achieves a large population in the oral microbiom...

Patricia Diaz, Empire Innovation Professor School of Dental Medicine The human body is filled with friendly bacteria. However, some of these microorganisms, such as Veillonella parvula, may be too nice. These peaceful bacteria engage in a one-sided relationship with pathogen Porphyromonas gingivalis, helping the germ multiply and cause gum disease, according to a new UB-led study. The research sought to understand how P. gingivalis colonizes the mouth.

Microbiome study: Gum disease-causing bacteria borrow growth molecules from neighbors to thrive Patricia Diaz, DDS, PhD, Professor of Empire Innovation in the UB School of Dental Medicine and director of the UB Microbiome Center. “Successfully targeting the accessory pathogen V. parvula should prevent P. gingivalis from expanding within the oral microbial community to pathogenic levels. ” Patricia Diaz, DDS, PhD, Professor of Empire Innovation and director, UB Microbiome Center School of Dental Medicine BUFFALO, N.Y. – The human body is filled with friendly bacteria. However, some of th...
