“…The gender Trichuris vulpis was identified in 3.33% of the samples. With results superior to those of the present study, Savilla et al (2011), Barros et al (2018), Chagas et al (2019) and Antunes et al (2020) diagnosed the parasite in 7.8%, 20.70%, 20.8% and 10.88% of the samples evaluated, in West Virginea, the United States, and in Brazil, specifically, in Pelotas, Rio Grande do South, Valença and Rio de Janeiro, respectively.…”

“…Of the total samples evaluated, it was found that the genus Ancylostoma caninum was the most abundant, totaling 24 (80%); the other information is contained in Table 1. In this context, corroborating this study, Chagas et al (2019) evaluated the feces of dogs belonging to different districts and municipalities, at the time the presence of ancylostoma was diagnosed in 63.81% of the animals evaluated. Barros et al (2018) conducted a study in Rio de Janeiro on public roads and found the presence of Ancylostoma spp.…”

Os parasitas zoonóticos são comumente identificados em ambientes que favorecem o seu desenvolvimento e lhes permitem completar o ciclo de vida, influenciados diretamente pelas condições climáticas e por consequência podendo afetar a saúde humana. O objetivo neste estudo foi identificar parasitas com potencial zoonótico em fezes de cães em praças públicas e nas ruas da área urbana da Amazônia. O estudo ocorreu em Jacareacanga, Sudoeste do Pará, Brasil. As amostras foram coletadas no período de 22 de janeiro a 22 de fevereiro de 2020, obtendo-se um total de 118 amostras de fezes caninas, em 5 bairros diferentes, principalmente em praças públicas e nas ruas do município de Jacareacanga, Sudoeste do Pará. Utilizou-se a técnica de Holffman para investigar a presença de ovos de parasitas. As análises estatísticas foram realizadas no programa R Studio versão 1.3.1093 a 5 % de significância pelo teste qui-quadrado de aderência e test Post-Hoc fdr (Benjamini & Hochberg -1995) para comparar os pares de categorias. Como resultados, foi possível identificar que houve diferenças (p<0,05) entre os parasitas encontrados, sendo que a maioria eram Ancylostoma (80%), seguido por Strongyloides (10%), Toxocara canis (3,33%), Trichuris vulpis (3,33%) e Ascaris Lumbrigoides (3,33%). Portanto, conclui-se que a técnica utilizada foi eficaz para identificar ovos de parasitas zoonóticos e que dentre os que foram identificados, merece destaque o Ancylostoma canis. Assim, fica evidente a necessidade de intervenção a fim de reduzir a contaminação do ambiente estudado concomitante com a desverminação efetiva dos animais. Palavras-chave: Ancilostomídeos.

Abstract Zoonotic parasites are commonly identified in environments that favor their development and will allow them to complete their life cycle, directly influenced by climatic conditions and, consequently, affecting human health. This study aimed to identify eggs of parasites with zoonotic potential in dogs’ feces in public squares and streets in the urban area of a municipality in the eastern Amazon, Brazil. The samples were collected from January 22nd to February 22nd, 2020, obtaining a total of 118 dogs’ feces, in 5 different neighborhoods, mainly in public squares and streets of the municipality of Jacareacanga, Southwest of Pará. Holffman's technique was used to investigate the presence of parasite eggs. Statistical analyzes were performed using the R Studio software version 1.3.1093 at 5% significance by the chi-square test of adherence and Post-Hoc fdr test, to compare pairs of categories. As a result, it was possible to identify that there were differences (p <0.05) among the parasites found, and the the majority was Ancylostoma (80%), followed by Strongyloides (10%), Toxocara canis (3.33%), Trichuris vulpis (3.33%) and Ascaris Lumbrigoides (3.33%). Therefore, it is concluded that a technique used was effective to identify zoonotic parasite eggs and that among those that were identified, Ancylostoma canis deserves to be highlighted. Thus, the need for intervention is evident in order to reduce the contamination of the studied environment concomitant with the effective animals devermination . Keywords: Hookworms. Strongyloides. Toxocara.

“…Among the zoonotic parasitoses associated with dogs in tropical, subtropical and temperate regions are toxocariasis, cystic echinococcosis (CE) and visceral leishmaniasis, (Otranto et al 2017). Some parasites registered in South America, such as Echinococcus granulosus, T. canis and Ancylostoma caninum (Chagas et al 2019;Ritossa et al 2021), can cause diverse zoonotic diseases like CE and the larva migrans visceral and cutaneous syndromes (Amundson Romich 2008). Other parasites, like Trichuris vulpis, are distributed throughout the world but rarely transmitted to humans.…”

In many countries, urban areas are commonly contaminated with canine feces that spread parasites, a situation related to the natural and social environment. Dogs having free access to public areas therefore constitutes a health risk. Because in Patagonia there are no records of city comparisons that consider the number of free-roaming dogs and the local environmental and socioeconomic characteristics, in this study we analyse and compare canine parasitoses in two cities of Rio Negro province, Argentina. Canine feces were collected from public areas of El Bolsón and Cipolletti cities and examined using enrichment methods, Kinyoun stain and immunoassay (Copro-Elisa). The total percentage of positive feces in El Bolsón was 68.95% and 16 parasite taxa being identified, whereas in Cipolletti the total positive feces was 41.1%, with 11 taxa. Both cities presented more helminth species than protozoans. The variables that explained the occurrence of all parasites were rainfall and socioeconomic stratum with the highest values being found in low-income areas. Soil moisture is conditioned by rainfall. This study highlights the presence of the zoonotic Echinococcus sp. in dogs in urban areas of the Rio Negro province. The occurrence of this parasite in Cipolletti is unexpected, given that this city is not considered an endemic zone for this disease, which is not included in local monitoring and control plans.
