AB Microplastics are small plastic particles (5 mm-1 µm size) that come from thedegradation of bigger plastics or have already been manufactured with this sizefor specific uses.Due to the degradation they suffer, microplastics can be accumulated in theenvironment, being a source of contamination. Moreover, they can be ingested by animals like birds or fishes. Besides, it has been recently studied that exists a certain relation between microplastics and microorganisms, being suitable habitats for their growth and development.In the present work, it was studied the presence of free-living amoebas (FLA)in microplastics from sea water and sand collected in Playa Grande, Tenerife.FLA, a group of protozoa, are widely distributed in the environment, beingcausal agents of some serious infections that can affect the Central NervousSystem (CNS), such as blinding keratitis and granulomatous encephalitis.We have isolated Acanthamoeba spp. from the microplastics extracted on thesand. It was observed the stellate morphology of this genus cysts. The samplewas analyzed at the microscope and confirmed by the specific PCR.These preliminary results show that, there could be a positive relationbetween the growth of FLA and microplastics, making them an ideal habitat for their development.
