Rev Soc Bras Med Trop. 2014 Jan-Feb;47(1):113-5. doi: 10.1590/0037-8682-0031-2012. Epub 2014 Feb 1.

Abstract

Introduction: This study assessed the prevalence of Mansonella ozzardi in riverine communities of the Tefé River, Amazonas, Brazil.

Methods: The prevalence of M. ozzardi was estimated by microscopic examination of thick blood smears.

Results: The M. ozzardi prevalence rate was 6.3% (19/300). Filarial infection was found in 8 of the 11 communities surveyed, with prevalence rates varying from 2.5% to 22.2%.

Conclusions: Tefé is a region of oil and natural gas exploration, in which there is a high turnover of workers. Migration patterns may facilitate the dissemination of mansonelliasis to other regions.
