The prevalence and distribution of filarial infections among the inhabitants of adjacent regions of the Departamento del Meta, Intendencia del Casanare, and Comisaría del Vichada in northeastern Colombia was determined by collection and examination of blood samples using the Knott's method. Mansonella ozzardi, the only species detected, was found in 2.5% of the samples collected in Meta (6/243), in 4.9% from Casanare (12/247) and in 2.5% from Vichada (3/137). All of the microfilaria carriers were Indians who had migrated from other parts of eastern Colombia, principally from the interior of Meta and Vichada. These results indicate that filariases are not endemic in the regions examined, and suggest that influx of microfilaria carriers with sufficiently high microfilaremia could establish new foci of transmission in areas where appropriate vectors are abundant.
通过使用诺特氏法采集和检测血样，确定了哥伦比亚东北部梅塔省、卡萨纳雷行政区和比查达警区相邻地区居民中丝虫感染的流行情况和分布。检测到的唯一物种是奥氏曼森线虫，在梅塔采集的样本中有2.5%（6/243）呈阳性，在卡萨纳雷为4.9%（12/247），在比查达为2.5%（3/137）。所有微丝蚴携带者均为从哥伦比亚东部其他地区迁移而来的印第安人，主要来自梅塔省和比查达省的内陆地区。这些结果表明，在所检查的地区，丝虫病并非地方病，并提示微丝蚴血症水平足够高的微丝蚴携带者的流入，可能在有大量适宜传播媒介的地区建立新的传播疫源地。
