Lancefield Group of Streptococci Isolated from Dental Plaque Biofilm

Abstract

The purpose of this study was to detect Lancefield group of Streptococci from different disease diagnosed in dental patient visiting the clinic. A total of 500 dental samples of plaque biofilm isolates were tested. Plaque sampling site varied depending on the condition and disease diagnosed in individual subjects. The plaque biofilm samples were collected from subgingival and supragingival including cervical margin of all erupted teeth. Oral diseases such as aphthous stomatitis, burning mouth syndrome, gingivitis, dental plaque and early onset of periodontitis harboring Lancefield group of Streptococci revealed their varied titer depending on disease condition. Strains were identified and differentiated with a simple enzyme extraction method that detects Streptococci Lancefield groups A, B, C, D, F and G. Group D showed highest titer in early onset of periodontitis and aphthous stomatitis oral infection. This latex method showed good discriminative ability for differentiation between these species, and suggested that it is a technique suitable for epidemiological studies on Lancefield group of Streptococci isolated from dental plaque biofilm from different disease condition.
