Abstract

INTRODUCTION Mansonella ozzardi is a widely distributed filaria worm in the Amazon region. This study aimed to determine the prevalence of M. ozzardi infection in riverine communities of Lábrea municipality, Amazonas State, Brazil. METHODS A diagnostic blood filtration method in a polycarbonate membrane was used. RESULTS M. ozzardi was found in 50.3% of the sample, with the highest prevalence in farmers/fishermen (69.4%; χ 2 = -19.14, p<0.001). The prevalence was higher in longer-term residents (≥11 years; 60.2%). CONCLUSIONS M. ozzardi infection rates are high near the Purus River, much greater than those previously reported based on diagnosis using thick blood smears.

摘要

引言奥氏曼森线虫是一种广泛分布于亚马逊地区的丝虫。本研究旨在确定巴西亚马孙州拉布雷亚市河岸社区奥氏曼森线虫感染的流行情况。方法采用聚碳酸酯膜诊断性血液过滤法。结果在50.3%的样本中发现了奥氏曼森线虫，农民/渔民中的流行率最高（69.4%；χ2 = -19.14，p<0.001）。长期居民（≥11年）中的流行率更高（60.2%）。结论在普鲁斯河附近，奥氏曼森线虫感染率很高，远高于此前基于厚血涂片诊断报告的感染率。
