Abstract

Little is known about the role of horse flies in potential pathogen transmission in Chile. This study provides evidence of the molecular detection of microorganisms in southern Chile. In the present study, adult Osca lata horse flies were trapped from Punucapa (39°45'06"S/73°16'08"W, Región de Los Ríos) and Puyehue (40°39'10"S/72°10'57"W, Región de Los Lagos), Chile. Among the 95 samples analyzed by PCR using specific primers, microorganisms were detected in 23.2% (n = 22) of the samples. Rickettsia spp. DNA was detected in 15.8% (n = 15) of the samples, Trypanosomatidae DNA in 5.3% (n = 5) of the samples, and filarial DNA in 2.1% (n = 2) of the samples. This study found that horse flies in the region are capable of carrying a variety of both parasites and endosymbionts. Further research is needed to understand the specific impact of horse flies as mechanical or biological vectors and develop effective control measures to prevent the spread of any microorganisms associated with disease.

摘要

关于马蝇在智利潜在病原体传播中的作用知之甚少。本研究提供了在智利南部检测到微生物的分子证据。在本研究中，从智利的普努卡帕（39°45'06"S/73°16'08"W，拉雷奥哈地区）和普耶韦（40°39'10"S/72°10'57"W，拉戈斯地区）捕获了成年的 Osca lata 马蝇。在使用特异性引物通过 PCR 分析的 95 个样本中，23.2%（n=22）的样本中检测到微生物。15.8%（n=15）的样本中检测到立克次体属 DNA，5.3%（n=5）的样本中检测到锥虫 DNA，2.1%（n=2）的样本中检测到丝虫属 DNA。本研究发现，该地区的马蝇能够携带多种寄生虫和内共生体。需要进一步研究以了解马蝇作为机械或生物传播媒介的具体影响，并制定有效的控制措施来防止与任何疾病相关的微生物的传播。
