Soil contamination by protozoan parasites and soil-transmitted helminths (STH) is common in beach sand due to a number of factors such as pets, pluvial water, garbage, etc. These pathogens may cause many diseases humans animals become public health problem. Thus, systematic evaluation inspection are necessary develop control strategies regarding contamination. For this purpose, our aims were evaluate the parasitic profile sandy soils on an urban untouched correlate with environmental seasonal characteristics Ubatuba, Brazil, two seasons (winter summer). 132 soilsamples collected for parasite analysis utilizing Rugai’s method sedimentation adapted method. Our results showed positivity 62% samples at least one no structures beach. The was higher summer (85%) than winter (51.7%). All positive both, protozoa. Seasonal influence noted presence STH while protozoa not observed. most found larvae hookworms (35%) Toxocara eggs (31.7%). We also Strongyloides sp, Ascarislumbricoides, coccidia, Dipylidium caninum, Entamoeba hystolitica/dispar, Endolimax nana, coli, Giardia Toxascaris leonina, Trichuris sp Dibothricephalus latus. There correlation between temperature samples. Most collection sites presented dogs or canine traces garbage both seasons. association their structures. In conclusion, seasonality, urbanization pets beaches can potentially favor increasing risk oftransmission zoonotic diseases.KEY WORDS: Soil-transmitted helminths; protozoa; contamination; sand; beaches.
