Identificación de amebas de vida libre en fuentes de agua en parques recreacionales peruanos

Resumen


Se han identificado amebas de vida libre (AVL), como Acanthamoeba, Naegleria, Balamuthia y Vermamoeba, tanto en entornos naturales como creados por el hombre, como aguas termales y spa. Naegleria fowleri causa meningoencefalitis amebiana primaria, mientras que Acanthamoeba y Balamuthia causan encefalitis granulomatosa crónica. Acanthamoeba también puede causar lesiones cutáneas y queratitis amebiana Este estudio tuvo como objetivo identificar la presencia de estos protozoarios en 4 playas y sedimentos marinos del litoral peruano. Las muestras de agua de playa y sedimentos se recogieron en forma esteril y se trasladaron al laboratorio para la identificación de las AVL y, la determinación de la calidad bacteriológica de las muestras de agua. La AVL mayormente identificada fue Acanthamoeba tanto en las playas como en los sedimentos de Totora, Boquerón, Talareño y Cangrejito, seguida de Heteramoeba y Mayorella. Aunque las infecciones debidas a amebas patógenas se consideran raras, recientemente, estas amebas mortales se detectaron en playas del litoral peruano. Esto es motivo de especial preocupación, especialmente porque el calentamiento global exacerba aún más el problema.
