Biology

Gingivitis is a Periodontal pathogen that causes dental plaques.There are more than 500 species in the oral cavity. A study statesthat at least 3 genera of bacterial isolates were able to stimulatelight production and about 170 were able to respond to theautoinducer AI-2. The signal for AI-2 induces the growth of thebacteria which eventually increases the severity of theinfection.
a) Since 170 bacterial isolates respond to AI-2 quorum sensingalone, how many bacterial isolates use:
agr quorum sensing
hsl quorum sensing
AI-2/agr quorum sensing
AI-2/hsl quorum sensing?
b) If AI-2 induces growth and increases the severity ofinfection, do bacteria that use agr quorum sensing do the samething or do they differ? What about bacteria that use hsl quorumsensing?
