Free-living amoebae (FLA) are widely distributed protozoa in the environment and have been isolated from many sources such as dust, soil and water. Furthermore, some genera/species of FLA such as Naegleria fowleri, Balamuthia mandrillaris and Acanthamoeba spp. are also able to cause opportunistic infections in humans and other animals. More recently, FLA have been reported to be environmental carriers of pathogenic bacteria, fungi and viruses, and thus have gained further importance from the public health point of view. Among them, Acanthamoeba spp. and Vermamoeba vermiformis have been described in many occasions as the most common carriers of pathogens of high medical relevance such as Legionella pneumophila and Mycobacterium spp. In this study, 24 soil samples were collected from the island of El Hierro, Canary Islands, Spain, in order to check for the presence of V. vermiformis strains in these samples. Soil samples were cultured on 2 % non-nutrient agar plates covered with a thin layer of heat-killed E. coli and checked daily for the presence of Vermamoeba. After a week, V. vermiformis amoebae were observed in 5 of the 24 processed samples (20.8 %) incubated at room temperature and 37 °C. Molecular characterization was carried out by amplifying the 18S rDNA gene and DNA sequencing, confirming that the isolated strains belonged to Vermamoeba vermiformis species. The high percentage of V. vermiformis in the studied soil sources should raise awareness in the region since these amoebae are potential environmental carriers of pathogens of high medical relevance.
