“…However, this result is slightly lower than that reported by Antonios et al (2008), Espinoza et al (2010). The prevalence of helminthes was higher in soil than stools samples while the prevalence of Protozoa was higher in stool than soil samples in urban area and the difference was very highly significant (P \ 0.001) Difference in prevalence could be as a result of difference in selected target population or the used diagnostic techniques of toxocariasis.…”

Soil transmitted helminths are highly prevalent throughout the developing countries of the world and Egypt is categorized as one of the developing countries. This study aimed to detect the relation between the presence and prevalence of STH in the soil and their reflection on the prevalence among school-children living in rural and urban areas in Zagazig district, Egypt. The present study was carried out on (859) school-children aged 6-13 years in Zagazig district all over the year 2013. They were subjected to stool examination. Out of them 100 suspected children were serotested for anti-TES IgG antibodies Toxocara spp. Soil samples also were collected from their places and regions. The results showed overall prevalence of parasitic infections was 21.07 % for helminthic infection and 39.46 % for protozoa. The prevalence of parasitic infections was more among children in rural areas (28, 49.2, 11.1 %) than those who live in urban areas (6.4, 18, 2.2 %) for helminths, protozoa and Toxocara as the most prevalent helminth respectively. Highly significant association was found between soil-transmitted helminthic infections detected by stool examination of the studied children group and the prevalence of geohelminthes in the examined soil samples, taken from residency areas of those children. This association was missed regarding protozoal infections. According to the results, low level of education and consequently poor socioeconomic and hygienic conditions of families appear to be powerful determinants of infection. Thus, improving environmental sanitation is imperative for the control of soil-transmitted helminths.

“…However, in an international context, the seroprevalence in waste pickers is lower than those reported in some South American countries. Toxocara seroprevalences ranging from 21% to 39% have been reported in rural and urban populations in Bolivia [12], Brazil [13], Argentina [14]–[16], and Peru [17], [18]. In contrast, the seroprevalence in waste pickers is higher than the Toxocara seroprevalences less than 5% reported in Canada [19], [20].…”

BackgroundThe epidemiology of Toxocara infection in humans in Mexico has been poorly explored. There is a lack of information about Toxocara infection in waste pickers.AimsDetermine the seroepidemiology of Toxocara infection in waste pickers.MethodsThrough a case control study design, the presence of anti-Toxocara IgG antibodies was determined in 90 waste pickers and 90 age- and gender-matched controls using an enzyme-linked immunoassay. Associations of Toxocara exposure with socio-demographic, work, clinical, and behavioral data of the waste pickers were also evaluated.ResultsThe seroprevalence of anti-Toxocara IgG antibodies was significantly higher in waste pickers (12/90: 13%) than in control subjects (1/90: 1%) (OR = 14; 95% CI: 2–288). The seroprevalence was not influenced by socio-demographic or work characteristics. In contrast, increased seroprevalence was found in waste pickers suffering from gastritis, and reflex and visual impairments. Multivariate analysis showed that Toxocara exposure was associated with a low frequency of eating out of home (OR = 26; 95% CI: 2–363) and negatively associated with consumption of chicken meat (OR = 0.03; 95% CI: 0.003–0.59). Other behavioral characteristics such as animal contacts or exposure to soil were not associated with Toxocara seropositivity.Conclusions1) Waste pickers are a risk group for Toxocara infection. 2) Toxocara is impacting the health of waste pickers. This is the first report of Toxocara exposure in waste pickers and of associations of gastritis and reflex impairment with Toxocara seropositivity. Results warrant for further research.

“…These nematodes develop the adult stage in the intestines of cats and dogs, where each female produces 200 000 eggs per day. These eggs are eliminated from the body and become infecting after [2][3][4][5] weeks. After being ingested by humans, the larvae go through the intestinal wall, migrating via the veins into the liver and the rest of the body, where they remain as larvae [1] .…”
