A seroepidemiological study of endemic treponematosis (bejel) in Niger allows us to realise an anonymous non correlated screening of VIH infection in Nomads: Touaregs of Tchirozerine (Agadez), Peuls Boro of Bermo (Maradi). On the 424 Touaregs screened only one was seropositive to VIH2 infection confirmed with Western blot that means 0.23% of seroprevalency comparable to that 0.50% found in the general population. The seroprevalency of trepronematosis (VDRL + TPHA+) is 7% in the range of 5 to 15 years old (80%), period which corresponds to the transmission of Bejel. Moreover this population don't travel to the seaborder countries. Concerning the 213 of the Peuls Bororo screened we had only 3 undetermined reactions to Western blot 1 and 2, despite the high seroprevalence of the treponematosis (VDRL+ TPHA+): 22% mostly in the subjects of more than 15 years old (89.36%) which is the sexual intercourse and exodus period to the seaborder countries, where 66% of our VIH patients are infected.
在尼日尔进行的地方性密螺旋体病（比杰尔病）血清流行病学研究，使我们能够对游牧民（奇罗泽林的图阿雷格人（阿加德兹）、贝莫的富拉尼·博罗人（马拉迪））中的艾滋病毒感染进行匿名非关联筛查。在接受筛查的424名图阿雷格人中，只有1人经蛋白质印迹法确认对艾滋病毒2感染呈血清阳性，这意味着血清阳性率为0.23%，与普通人群中发现的0.50%相当。在5至15岁（占80%）这个与比杰尔病传播相对应的年龄段，密螺旋体病（VDRL + TPHA +）的血清阳性率为7%。此外，这个群体不会前往沿海国家。在接受筛查的213名富拉尼·博罗人中，尽管密螺旋体病（VDRL + TPHA +）的血清阳性率很高（22%，主要集中在15岁以上的人群中，占89.36%），这是性交和前往沿海国家的时期，我们的艾滋病毒患者中有66%在那里感染，但我们对蛋白质印迹法1和2只有3例未确定反应。
