dc.description.abstract | Microplastics are small plastic particles (5 mm-1 µm size) that come from the degradation of bigger plastics or have already been manufactured with this size for specific uses. Due to the degradation they suffer, microplastics can be accumulated in the environment, 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, being causal agents of some serious infections that can affect the Central Nervous System (CNS), such as blinding keratitis and granulomatous encephalitis. We have isolated Acanthamoeba spp. from the microplastics extracted on the sand. It was observed the stellate morphology of this genus cysts. The sample was analyzed at the microscope and confirmed by the specific PCR. These preliminary results show that, there could be a positive relation between the growth of FLA and microplastics, making them an ideal habitat for their development. | en |
