Free-living amoebae (FLA) such as spp., , , , and spp. are causal agents of deadly and/or disabling infections in humans. Despite recent data showing an increase in infection cases worldwide, studies on the prevalence of these emerging pathogens in water sources are scarce. Moreover, climate change is believed to facilitate the expansion and persistence of these environmental pathogens, further emphasizing the need for comprehensive surveillance. Therefore, the current study investigates the variety and abundance of free-living amoebae in different water sources in the autonomous community of Castilla y León, Spain, during different seasons of the year. was the most prevalent species and was detected in rivers, swamps, irrigation waters, swimming pools and recreational fountains. Moreover, genera such as and and were also identified. This study highlights the diversity of FLA in the region and their relationship with local water characteristics. Given that certain FLA species are opportunistic pathogens, these results emphasize the necessity of monitoring this area and water sources.
自由生活阿米巴（FLA），如 属、 属、 属、 属、 属和 属，是人类致命和/或致残感染的病原体。尽管最近的数据显示全球感染病例有所增加，但关于这些新兴病原体在水源中流行情况的研究却很少。此外，气候变化被认为会促进这些环境病原体的扩散和持续存在，这进一步凸显了进行全面监测的必要性。因此，本研究调查了西班牙卡斯蒂利亚-莱昂自治区不同季节不同水源中自由生活阿米巴的种类和丰度。 是最常见的物种，在河流、沼泽、灌溉用水、游泳池和休闲喷泉中均有检测到。此外，还鉴定出了 属、 属和 属等属。本研究突出了该地区自由生活阿米巴的多样性及其与当地水特征的关系。鉴于某些自由生活阿米巴物种是机会性病原体，这些结果强调了监测该地区和水源的必要性。
