“…This may be due to a better survival rate of Toxocara eggs in soil, or a higher number of reservoir animals found in some habitats. Blaszkowska et al (2011) detected Toxocara eggs in soil samples from three out of five examined field localities, confirming that agrocenoses are possible source of the infection. In Slovakia the first research of larval toxocarosis in small mammals was carried out in 1991 -1993 in localities with different anthropogenic pressure.…”

Small rodents — permanent reservoirs of toxocarosis in different habitats of Slovakia

The study aimed to estimate the role of small rodents in the circulation of larval toxocarosis in light of their different habitats. From 2005 to 2008, a total of 1523 small rodents, belonging to 11 species, were captured in 5 different habitats of Slovakia. Anti-Toxocara antibodies were detected in 6.6 % animals. The dominant reservoirs of toxocarosis were striped-field mouse Apodemus agrarius (11.7 %) and mound-building mouse Mus spicilegus (10.7 %), while the seropositivity of voles was low. Sexually active adults were infected more frequently (10.8%) in comparison with inactive ones (5.2 %). According to habitats, seroprevalence of toxocarosis in windbreaks (2.4 %) was significantly lower (p < 0.05) than in agrocoenoses (6.7 %), alluvia (8.5 %) and ecotones (7.5 %). Log-linear analysis performed in A. agrarius indicates that type of habitat and sexual activity affect the seropositivity to Toxocara infection. The highest seroprevalence was observed in alluvium (21.2 %) while the lowest in windbreak (1.8 %) (χ 2 = 17.232, p < 0.001) and sexually active mice were characterised by 22.5 % and sexually inactive by 6.4 % seroprevalence (χ 2 = 30.634, p < 0.001). The occurrence pattern of toxocarosis in small rodents suggests that they are permanent reservoirs for Toxocara spp. in nature and significant indicators of Toxocara egg contamination in environs.

“…According to our finding, consuming unwashed salad vegetables may cause Toxocariasis. This study did not differentiate between Toxacara cati and T. canis eggs as these two species eggs have a highly similar morphological appearance (Blaszkowska et al, 2011).…”

“…eggs attached to vegetables was 21% and were found to be the highest detected parasite in salad vegetables examined, our findings agrees with the previous studies. This study did not differentiate between A. lumbricoides and Ascaris suum eggs as these two species eggs have a highly similar morphological appearance (Blaszkowska et al, 2011).…”

A b s t r a c tOne of the main ways in transmitting parasites to humans is through consuming contaminated raw vegetables. The aim of this study was to evaluate the prevalence of parasitological contamination (helminthes eggs, Giardia and Entamoeba histolytica cysts) of salad vegetables sold at supermarkets and street vendors in Amman and Baqa'a -Jordan. A total of 133 samples of salad vegetables were collected and examined for the prevalence of parasites. It was found that 29% of the samples were contaminated with different parasites. Of the 30 lettuce, 33 tomato, 42 parsley and 28 cucumber samples examined the prevalence of Ascaris spp. eggs was 43%, 15%, 21% and 4%; Toxocara spp. eggs was 30%, 0%, 0% and 4%; Giardia spp. cysts was 23%, 6%, 0% and 0%; Taenia/Echinococcus eggs was 20%, 0%, 5% and 0%; Fasciola hepatica eggs was 13%, 3%, 2% and 0%; and E. histolytica cysts was 10%, 6%, 0% and 0%, respectively. There was no significant difference in the prevalence of parasite in salad vegetables either between supermarkets and street vendors, or between Amman and Baqa'a, Ascaris spp. was found to be the highest prevalent parasite in salad vegetables from supermarkets and street vendors and from Amman and Baqa'a. Our results pointed out that, the parasitic contamination of salad vegetables found in our study might be caused by irrigating crops with faecal contaminated water. We concluded that salad vegetables sold in Amman and Baqa'a may cause a health risk to consumers. K e y w o r d s: Amman, Baqa'a refugee camp, contamination, parasite, salad vegetable

“…In the study conducted in rural regions of Łódź Province, Ascaris, Toxocara and Trichuris eggs were revealed in 4% of examined soil samples from gardens, and 60% from yards, with Toxocara spp. eggs the most often found [5]. The same group of researchers [11] found helminth eggs from 4 genera, namely Toxocara, Trichuris, Ascaris, Uncinaria/Ancylostoma in 9.3% of samples from public sites in the urban area of Łódź, such as park playgrounds, school sports fields and sandpits in school or kindergarten areas; Toxocara eggs were predominant in the examined sites.…”

“…According to numerous reports, the rural environment predisposes for the acquisition of geohelminth infections, and therefore more frequently affects the possibilities of such an acquisition due to close contact with soil, vegetation and aunwashed vegetables and fruits. Field surveys conducted in different rural settlements show a high rate of soil contamination with eggs of nematode parasites, in particular, Toxocara, Ancylostoma/Uncinaria and Trichuris [1,2,3,4,5,6], some of which infect humans, while others, such as T. vulpis, Ancylostoma caninum and Uncinaria stenocephala, are potential zoonotic parasites [7,8]. Canine and feline roundworms (T. canis and T. cati) are of the greatest epidemiological importance [9,10], and their eggs are most frequently observed in examined sites [1,2,4,11,12].…”

The objective of this study was to evaluate the risk of soil transmitted zoonotic helminth infections for families with young children, inhabitants of villages in the Mazowieckie Province of Central Poland. Epidemiological survey was conducted at 33 randomly selected households with 2-3 children present. Examination of soil samples from yards surrounding the houses for the presence of geohelminth eggs was conducted, the households were inspected, and family members interviewed using a designed questionnaire. Among 55 localities examined, i.e. 33 backyards, 10 vegetable gardens and 12 sandpits, contamination was found in 2 backyards (6.1%) and 1 sandpit (8.3%) at 3 households (9.1%). Of the total 550 examined soil samples, 4 (0.7%) were found to contain Trichuris and Toxocara eggs, with an average density of 1.5 and 2.0 eggs per sample. The study showed a low level of soil contamination, which was the result of inhabitants care about the sanitation of their domiciles. However, the results of the questionnaire survey demonstrated the need to warn rural residents about the risk factors for zoonotic helmints infections. In particular, parents should be advised how to minimize the threat of parasitic diseases for children in the rural environment. The presented study showed that promotional campaigns implemented in recent years on the prevention of parasitic zoonoses have had little effect to increase the awareness of the rural community. The present results confirmed that Toxocara is the most common zoonotic agent among geohelminths in the rural environment.
