The study aimed to estimate the prevalence of Mansonella ozzardi and calculate the parasitic infection rate in simuliid blackflies. The research was conducted in communities on the Purus River, Boca do Acre municipality, Amazonas State, Brazil. Prevalence was measured using the thick smear method. Captured blackflies were dissected to verify the parasitic infection rate. M. ozzardi prevalence was 27.30% (77/282). The study showed higher prevalence in men (31.97%) than women (22.22%), farmers (48.99%), and individuals in the 38-47 (60.00%), 48-57 (66.66%), and 58-67-year age brackets (75.00%). Microfilaremia was higher in individuals 58 to 67 years of age (average= 58.41 mf/40 microl), men (41.44 mf/40 microl), and farmers (49.94 mf/40 microl). Only the simuliid Cerqueirellum amazonicum was found infected with a parasitic infection rate of 0.98%.
该研究旨在估算奥氏曼森线虫的流行率，并计算蚋属黑蝇的寄生虫感染率。研究在巴西亚马孙州博卡多阿克里市普鲁斯河沿岸的社区开展。采用厚涂片法测量流行率。解剖捕获的黑蝇以核实寄生虫感染率。奥氏曼森线虫的流行率为27.30%（77/282）。研究表明，男性（31.97%）的流行率高于女性（22.22%），农民（48.99%）以及年龄在38 - 47岁（60.00%）、48 - 57岁（66.66%）和58 - 67岁（75.00%）的人群。58至67岁的个体（平均 = 58.41条微丝蚴/40微升）、男性（41.44条微丝蚴/40微升）和农民（49.94条微丝蚴/40微升）的微丝蚴血症较高。仅发现亚马孙塞尔克雷蚋感染，寄生虫感染率为0.98%。
