Abstract

The prevalence of microfilaremia among Indians in 13 Amazon Indian villages was determined by examining Giemsa-stained peripheral blood smears and preparations from peripheral blood lymphocyte cultures. Mansonella ozzardi was the only species found in the 601 persons tested. Prevalence was highly village-specific, ranging from 0% in four villages to as high as 93% among persons aged 10 years and older in others. Comparisons of the two methods showed that the concentration effect of the peripheral blood lymphocyte culture preparations allowed the detection of a greater number of microfilaria-positive persons, especially women and children with lower levels of parasitemia.

摘要

通过检查吉姆萨染色的外周血涂片和外周血淋巴细胞培养物制备物，确定了13个亚马逊印第安村庄中印度人的微丝蚴血症患病率。在接受检测的601人中，奥氏曼森线虫是唯一发现的种类。患病率因村庄而异，在四个村庄中为0%，而在其他村庄10岁及以上人群中高达93%。两种方法的比较表明，外周血淋巴细胞培养物制备物的浓缩效应使得能够检测到更多的微丝蚴阳性者，尤其是寄生虫血症水平较低的妇女和儿童。
