[Study on inspection method of anaerobes in periodontal pockets]

This paper used two methods only use non-selective medium(CDC) and together with seven selective mediums(VS CS BS AS FS ES LS) to inspect anaerobes in periodontal pockets.The results showed that Gram-negative anaerobes were the predominant microflora of periodontitis.The method of CDC together with selective mediums was founded much simpler and faster,more valuable than the method of only use non-selective medium.It is illustrated that CDC added antibiotics or chemicals to make selective mediums was prepared convenience and was suitable for growth of relative anaerobes.But it is still necessary to establish much more,more special, more reliable selective or identical mediums.
