“…Papajová et al (2014) stated that up to 70 % of dog feces in the Slovakian territory are found on lawns with dwelling houses nearby. A similar situation is also in other countries (Mizgajska, 2001;Rinaldi et al, 2006;Dubná et al, 2007;Cinquepalmi et al, 2013;Neves et al, 2014;Ramos et al, 2022). Batista et al (2019) reported that an increase in soil contamination by helminth eggs correlates with the rise of the human and pet population, especially in urban areas where owners don't collect dog waste from public areas.…”

Summary This study aimed to determine the prevalence of endoparasites in dog feces from public places, investigate the occurrence of endoparasites in soil, and identify potential risk factors associated with the dog endoparasites infection spread in East Slovak Lowland - the region near the EU border with Ukraine. In a one-year study, a total of 803 dog fecal samples and 148 soil samples from public places were examined for the presence of endoparasite developmental stages. In general, 43.59 % of dog excrements were positive. Six different species of intestinal parasites were detected: Toxocara canis (22.65 %), Trichuris vulpis (14.07 %), family Ancylostomatidae (10.09 %), Capillaria aerophilla (5.60 %), Ascaris spp. (1.49 %). Altogether, 52.03 % of soil samples were positive for at least one endoparasites species. The occurrence of parasitic eggs in the soil was as follows: Ascaris spp. (37.16 %), Toxocara spp. (29.05 %), Trichuris spp. (29.05 %) %), family Ancylostomatidae (2.03 %) and Toxascaris leonina (2.03 %). The occurrence of endoparasites between the towns and villages varied significantly. The distribution of endoparasites in dogs and soil was affected by the population density, the minority people living in the studied territory, the number of people living in poor hygienic conditions with limited access to drinking water and the usage of sewerage. Persisting endoparasitic contamination of the environment in East Slovak Lowland forms a reservoir with zoonotic potential representing public and environmental health problems.

“…We recognize that there are a variety of effective techniques for detecting parasites [46][47][48][49]53]. In this study, microscopic analysis was used for the detection of STH larvae and eggs as it is considered the gold standard technique for STH studies [54].…”

We assessed the prevalence of soil-associated parasites and non-pathogenic nematodes in eight public areas of Porto Alegre (Rio Grande do Sul state, southern Brazil), the most populous city in Rio Grande do Sul. Soil samplings were carried out during the winter of 2022 and summer of 2023: A total of 80 samples were collected in winter and 80 in summer (ten samples from each sampling site per season), totaling 160 soil samples. The frequency of microscopic non-pathogenic nematode larvae was significantly higher (p = 0.048) in winter (93.75%) than in summer (82.50%). Considering the pooled data from winter and summer (n = 160) for human pathogenic parasites, the following frequencies were observed (using microscopy analysis): hookworm (filariform) larvae (1.25%), hookworm (rhabditiform) larvae (11.25%), Strongyloides spp. (filariform) larvae (0.63%), Strongyloides spp. (rhabditiform) larvae (2.5%), hookworm eggs (10.63%), Ascaris spp. eggs (10.00%), and Trichuris spp. eggs (1.25%). Hookworm (rhabditiform) larvae were the most frequent parasitic structures (15.00%) in winter, and A. lumbricoides eggs were the most frequent parasitic structures (8.75%) in summer. No statistically significant difference was observed in the frequency of pathogenic parasites between the seasons (p > 0.05). Toxoplasma gondii DNA was assessed, but all soil samples tested negative in molecular analysis. Our results indicate that soil from many regions of Porto Alegre shows a high prevalence of soil-transmitted helminths, indicating the need for improvements in social conditions and environmental sanitation in the city. Our study also suggests that climate change may affect soil biodiversity, potentially harming non-pathogenic nematodes and favoring human pathogenic parasites.
