Several species of pathogenic Acanthamoeba cause infections to humans, but amoebic keratitis is more frequently found than any other due to the increasing number of contact lens wearers in the world. Cysts and trophozoites of these amebas are airborne and may pollute water from the air. We investigated the proportion of pathogenic Acanthamoeba from the atmosphere of the city of San Luis Potosi. Samples were taken by the impinger method, every month during one year. We isolated 23 strains of Acanthamoeba, 61% of them were non-pathogenic, 31% were non-pathogenic with invasive capacity and 8% were pathogenic to mice. Almost 40% of these strains represent danger of infections to humans. The isolations were more abundant during the dry season in the south (urban) and west (suburban) stations, which means that the sanitary conditions around stands may enhance the proportion of pathogenic strains in the surroundings.
