Abstract
This study aimed to evaluate the ovicidal activity of the hydroalcoholic extract of Schinus terebinthifolia (SCH; T1) against Ancylostoma spp. and its influence of storage time in the extract stored for 36 months (T36). Eggs of Ancylostoma spp. were obtained from naturally parasitized dogs, and used for the larval hatchability test, where the eggs were exposed to T1 and T36 extracts of SCH (15-0.625 mg/mL). In T1, all concentrations inhibited more than 80% of the eggs, being 100% at concentrations between 15 and 5 mg/mL (p > 0.05). At T36, all concentrations were active, even the ones between 2.5 and 0.625 mg/mL, with 100% inhibition (p < 0.05), revealing that the storage time maintained the ovicidal action. By LC-MS, T36 presented ethyl gallate, myricitrin, and gallic acid as major compounds. These findings support the promising use of SCH extract as an ovicide against Ancylostoma spp., even stored for 36 months of shelf life.

Abstract
vulnerability. The fact that these people share the environment with animals promotes the establishment of zoonotic parasitic infections, as well as the resultant parasitic cycles. Thus, parasites present in the environment must be identified, so that control measures can be recommended. In this context, this study’s objective was to evaluate environmental contamination by parasitic forms in a socially vulnerable community in southern Rio Grande do Sul. A total of 100 soil samples collected from the community were processed by a sodium dichromate centrifuge-flotation technique and analyzed by a compound microscope (40X objective) for the identification of parasite eggs, oocysts and cysts. All points were positive for two or more parasites, with the identification of 33.59% non-identified coccidian oocysts, Strongylida (25.4%), Ascaridida (21.31%), Trichuris spp. (8.19%), Toxocara spp. (3.27%), Amoebas (4.08%), Dioctophyma renale (2.45%), and Giardia spp. (1.63%). The presence of parasitic forms in all points analyzed surpasses other studies of environmental contamination carried out in the southern region of Brazil. In addition, the identification of several parasitic forms with zoonotic potential is concerning, since it shows the possibility of parasitic transmission to humans and other animals. In view of the results, the conclusion is that the environment analyzed is contaminated by parasitic forms, constituting a serious public health problem. Therefore, implementing educational and preventive measures in the community to control parasites is of crucial importance.
