Dirofilariasis is a mosquito-borne disease caused by Dirofilaria parasites, affecting both wild and domestic animals, including humans considered as accidental hosts. Dirofilaria repens is the principal causative agent of dirofilariasis in the Old World, with increasing reports of the parasite in countries where it has not been previously identified, due to several factors such as the expansion of mosquito vectors' geographical distribution. By utilizing newly designed primers for molecular detection and confirming through next-generation sequencing, here, we report the first plausible cases of D. repens in dogs from Colombia. Our results support the classification of this species as an emergent pathogen in the Americas. Finally, we encourage an increase in diagnostic and surveillance efforts to prevent and control the current and future dirofilariasis cases in this region.
犬心丝虫病是由犬心丝虫寄生虫引起的蚊媒疾病，影响野生和家养动物，包括被视为偶然宿主的人类。在旧世界，复孔绦虫是犬心丝虫病的主要病原体，由于多种因素，如蚊子传播媒介的地理分布扩大，在以前没有发现该寄生虫的国家，越来越多的国家报告了该寄生虫。通过利用新设计的分子检测引物，并通过下一代测序进行确认，我们在此报告了哥伦比亚首例犬心丝虫病的可能病例。我们的结果支持将该物种分类为美洲的新兴病原体。最后，我们鼓励增加诊断和监测工作，以预防和控制该地区当前和未来的犬心丝虫病病例。
