Abstract

Summary

The capacity of clinical isolates and type strains of to survive in a new transport medium (TM), phosphate-buffered saline (PBS) and Ringer's solution (RS) was evaluated. The effects of exposure to air, transportation time and temperature on viability were also studied. In addition, the culture of from subgingival plaque of patients with different forms of periodontitis was quantified. The results following storage in TM, PBS and RS showed that survived better in TM than in PBS or RS when transportation times exceeded 20-22 h, and that survival was enhanced by storage at below 12°C. Serotype b strains of were able to survive better than either serotype a or c. In the clinical study the optimal transportation conditions for subgingival plaque containing were TM at a temperature of 8°C for 24 h under anaerobic conditions. These conditions resulted in a high survival and isolation rate for without inhibition of the other periodontopathic bacteria isolated from deep periodontal pockets. These findings have practical implications for future multicentre clinical trials in which the transportation of oral specimens over relatively long distances and at different ambient temperatures during various periods of the year are required.
