Patricia Pérez-Pérez, Iván Rodríguez-Escolar, José E. Piñero, Rodrigo Morchón, Jacob Lorenzo-Morales
TL;DR
This study found a high diversity of potentially harmful free-living amoebae in water sources in Castilla y León, Spain, highlighting the need for monitoring due to their potential to cause infections.
Contribution
The study provides new insights into the prevalence and diversity of pathogenic free-living amoebae in water sources in a specific region of Spain.
Findings
Vermamoeba vermiformis was the most prevalent free-living amoeba species found in various water sources.
Acanthamoeba, Naegleria, and Vahlkampfia genera were also identified in the region.
The study emphasizes the need for monitoring due to the potential pathogenicity of these amoebae.
Abstract
Free-living amoebae (FLA) such as Acanthamoeba spp., Balamuthia mandrillaris, Naegleria fowleri, Sappinia pedata, Vermamoeba vermiformis and Vahlkampfia 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. Vermamoeba vermiformis was the most prevalent species and was detected in rivers, swamps, irrigation waters, swimming pools and…
