Polymerase chain reaction-based identification of various serotypes of in adults with and without dental caries.

Background: Dental caries is a multistep process which initiates the development of plaque' defined as a structured biofilm containing microbial communities. Teeth provide unique surfaces for bacterial colonization. Serotypes of implicate the development of dental caries.

Simultaneous detection and evaluation of , and in subgingival plaque samples of chronic periodontitis and healthy individuals through multiplex polymerase chain reaction.

Background: is a Gram-negative anaerobic bacilli. The phenotypic characteristics of the various species of are similar, which often makes it difficult in routine differentiation and identification of all the species.

Aim: The purpose of the study was to detect and compare presence of , and in subgingival plaque samples of chronic periodontitis and healthy individuals.
