Background: The high lethality rates in cases of human infections caused by free-living amoebae and their role as pathogenic microorganisms prompted their identification in environments such as soil. Currently, inputs are used to prepare substrates of ornamental plants in gardening, being farmland soil one of the most used because it can be mixed with other materials called ‘’soil mixtures’’. This commercial soil is distributed in our country. Objective: To isolate and identify Acanthamoeba spp. and Balamuthia mandrillaris from samples of commercial soil from a supermarket in Lima obtained in August 2019. Study design: A cross-sectional descriptive observational study was conducted. Material and methods: 30 bags with commercial soil were used, each soil sample from bags was sowed on Non-Nutrient Agar (ANN) enriched with Escherichia coli ATCC 25922, the identification of free-living amoebae was performed by PCR of the positive isolates. Results: Acanthamoeba spp. and one suggestive amoeba of the genus Vahlkampfia were isolated from 66.7% (20/30) and 3.3% (1/30) of commercial soil samples, respectively. Balamuthia mandrillaris was not isolated. Conclusions: The presence of potentially pathogenic amoebae in commercial soil distributed in a supermarket of Lima was evidenced, being the amoebae genus Acanthamoeba the most frequent.
