RESUMO

Aquilaria sinensis can generate agarwood, which is closely related with endophyte. Up to now, studies mainly focused on the effects of endophytic fungi on agarwood formation, but studies about endophytic bacteria are rarely reported. In our research, the T-RFs and Shannon index of endophytic bacteria in samples of agarwood increase. The number of distinctive T-RFs fragments of corresponding samples in the same group accounted for more than 60% the number of total T-RFs fragments. In samples of no-agarwood, the dominant bacterial population are Anoxybacillus, Clostridium, Candidatus endobugula, Lysinibacillus. In samples of agarwood, the dominant bacterial population are Clostridium, Lysinibacillus, Luteimonas, phytoplasma. Besides, there are. specific T-RFs fragment in samples of agarwood and no-agarwood respectively. When we perform cluster analysis, we found samples of agarwood highly gather together and samples of no-agarwood highly gather together. This means community of endophytic bacteria emerge significant and regular changes during agarwood formation, which may be result of agarwood production, or maybe it is important reason of agarwood production. In this paper, we obtain more comprehensive and accurate community of endophytic bacteria in Aquilaria sinensis and it's variation during agarwood formation using T-RFLP, which is first study of effects of endophytic bacteria on agarwood formation, and will help to exploit resource of endophytic bacteria more reasonably.

RESUMO

<p><b>OBJECTIVE</b>To observe the changes of intestinal flora in diarrhea type irritable bowel syndrome with Pi-wei dampness-heat syndrome (IBS-PDS).</p><p><b>METHODS</b>The seven kinds of common intestinal bacteria in feces, including enteri bacillus, enterococci, saccharomycete, bifid bacteria, lactobacillus, bacteroides and peptococcus were studied in 21 patients suffered from IBS-PDS, and compared with those in 22 patients with IBS with deficiency of Pi syndrome (DPS) and 25 healthy subjects as control.</p><p><b>RESULTS</b>As compared with the healthy subjects, the levels of enteri bacillus and enterococci were significantly increased (P<0.01), the levels of bifid bacteria, Lactobacillus and Peptococcus were significantly decreased (P < 0.01), and saccharomycete and Bacteroides were insignificantly different in patients with PDS. As compared with patients with DPS, the levels of enteri bacillus, enterococci, bifid bacteria, Lactobacillus, Peptococcus and Bacteroidaceae were significantly increased except the level of saccharomycete.</p><p><b>CONCLUSION</b>There may be alteration of intestinal flora in patients with IBS-PDS.</p>
