The investigators, led by Marie-Laure Chaix, MD, from the Necker Hospital in Paris, France, found that among 12 HIV-infected men who presented with acute HCV infection, the only significant risk factor reported by all patients was sexual exposure. Ten of the 12 patients were infected with HCV genotype 4, subtype 4d, and all of these infections were found to be closely related by type on phylogenetic analysis.

A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

从每种基因型中随机选择一个克隆子作为代表进行测序分析，所有序列与GenBank数据库中序列的同源性为87%~100%，且两样地中均有超过一半的基因型序列与数据库中已知序列同源性低于97%，属于分类在"种"地位上的新发现细菌；通过系统发育研究将两样地的细菌分为10大类群，两样地共同拥有5大类群，但两样地的细菌优势类群明显不同，原生土壤为Proteobacteria，含39种基因型，占总克隆子数的58.0%，退化生态系统土壤为Acidobacteria和Proteobacteria，分别含19种和15种基因型，占总克隆子数的32.5%和30.5%；与原生土壤细菌类群相比，退化生态系统土壤Proteobacteria类群明显减少，Acidobacteria类群明显增加。
