Estudio de la presencia de huevos de Toxocara sp. en suelos de áreas públicas de la ciudad de Chillán, Chile

Contaminación De Parques Públicos (Jesús De Nazareno, Ayacucho- Perú) Con Huevos De Toxocara

“…; son asimismo superiores al 18% encontrado en Cuba (Duménigo & Gálvez, 1995) y 33,3% en Argentina (Alonso et al, 2006. Recientemente en parques públicos de Chile no se encontró la presencia de este parásito (Melín-Coloma et al, 2016). Montalvo-Sabino et al (2014) evaluaron su presencia en parques públicos de Huánuco, Perú.…”

Factors associated with the presence of helminth eggs in the soil of public areas in Concepción, Chile

“…Some have focused on domestic environments, either considering dogs visiting a veterinary clinic (Ferreira et al, 2016;Tamponi et al, 2017) or analyzing the presence of parasites in dog feces within the domicile (Acosta-Jamett et al, 2014;Quilodrán-González et al, 2018). Others have analyzed the presence of zoonotic parasites in public areas (Sprenger et al, 2014;Medina-Pinto et al, 2018;White et al, 2019), where many have reported parasite findings of high diversity or frequency (Sprenger et al, 2014;Ferreira et al, 2016); still, others have reported not finding any parasites at all (Melín-Coloma et al, 2016). Interpreting the level of risk in these studies is not easy to accomplish given the differences in the design and laboratory techniques used, which can yield different results (Collender et al, 2015).…”

“…Interpreting the level of risk in these studies is not easy to accomplish given the differences in the design and laboratory techniques used, which can yield different results (Collender et al, 2015). In studies of parasites in public environments, some differences are easily visible in terms of study design; for example, some studies focus on the presence of parasites in feces in public areas (Medina-Pinto et al, 2018;Utaaker et al, 2018), while others focus on the presence of parasites in the ground (Sprenger et al, 2014;Melín-Coloma et al, 2016). Thus, it is not easy to determine whether the design of the study contributes to these differences in results, nor is it possible to elucidate how these differences translate into different risk levels of human infection.…”

“…One important factor to consider in the study of parasites in public areas is the representativity of the areas sampled. For example, most studies have focused on licensed public areas, which are gardened and frequently cleaned (Sprenger et al, 2014;Melín-Coloma et al, 2016). In addition, some studies have focused on taking soil samples at a distance from feces, suggesting that the close presence of feces could affect the results (Sprenger et al, 2014;Melín-Coloma et al, 2016).…”

The type of ground surface is another factor that can affect the finding of parasites; for instance, some studies have focused on sand (Sprenger et al, 2014), others have focused on and compared both soil and grass, and others have analyzed soil thickness (Iannacone et al, 2012).…”
