title: [Phylogenetic analysis of symbiotic archaea in the gut of Reticulitermes chinensis Snyder].
abstract: OBJECTIVE
  To analyze the phylotypes of symbiotic archaea in the gut of Reticulitermes chinensis Snyder by using non-cultivating method.
  
  
  METHODS
  We amplified 16S rRNA genes of the symbiotic archaea from the DNA extract of the whole gut with the universal archaeal 16S rDNA primer. A clone library of archaeal 16S rDNA was established and selected clones were sequenced and phylogeneticly analyzed.
  
  
  RESULTS
  Five 16S rDNA sequences with the similarity between 93.2% and 99.2% to each other were obtained from Reticulitermes chinensis Snyder. Phylogenetic analysis showed that the five clones were clustered with Methanobrevibacter clones or isolates obtained from Reticulitermes speratus and Reticulitermes flavipes.
  
  
  CONCLUSIONS
  The results showed that symbiotic archaea in the gut of Reticulitermes chinensis were affiliated with Methanobrevibacter.
