“…Vegetables or fruit contaminated with Ascaris and Toxocara eggs represent important factors of transmission for rural and urban inhabitants (Vazquez Tsuji et al, 1997). In studies conducted by Ulukanligil et al (2001) in Sanliurfa (Turkey) A. lumbricoides eggs were detected in 11.0 % of unwashed vegetables tested. Choi and Lee (1972) found Ascaris eggs in 49.0 % of 147 lettuce samples that were collected from markets in Taegu (Korea).…”

“…In the world, especially in developing countries, uncontrolled use of natural manure (e.g. cowpat, water from sources contaminated with human and animal excrement) to fertilize vegetables and fruits has been reported to be responsible for their high rates of contamination with helminth eggs (Takayanagui et al, 2000;Ulukanligil et al, 2001). In Turkey, helminth eggs were detected in 12 (5.9 %) of 203 unwashed samples of raw vegetables from wholesalers in Ankara (Kozan et al, 2005) where Toxocara spp.…”

SummaryContamination of soil with helminth eggs in the samples of fields, kitchen gardens, yards and composts in rural areas of Lodz district (Poland) was investigated. In this study, helminth eggs were found in 60 -100 % of field samples, in 20 -100 % of yards samples, in 0 -20 % of kitchen gardens samples and in 10 -100 % of composts. The highest average density of helminth eggs in 100 g of soil was detected in composts (44.0), then fields (28.5) and yards (18.0). In samples taken from kitchen gardens the average density of eggs was 0.4/100/g of soil. The comparison of frequency of positive samples from fields, kitchen gardens and yards did not exhibit significant difference (p > 0.05). The soil samples of fields contained mainly eggs of Ascaris spp. (87.7 %), less frequently Toxocara spp. (7.7 %) and Trichuris spp. (3.5 %). In samples from yards among detected eggs the most often were Toxocara spp. (73.9 %), and there were statistically significant differences in comparison with fields (7.7 %) and composts (0.3 %). The highest prevalence of eggs with moving larva was noted in yards (25.6 %), which differ statistically significantly from analogous value for fields (p < 0.05) and composts (p < 0.0001). These results showed a considerable infestation of soil with geohelminth eggs of the examined rural areas of Lodz district which is a potential source of antropozoonosis.

“…The increased demand, global sourcing and rapid transport of foods, especially soft fruit and salad vegetables, enhance both the likelihood of source contamination and survival of the transmissive stages of parasites pathogenic to man (Slifko, Smith, & Rose, 2000). In developing countries, especially, uncontrolled use of water from sources contaminated with human and animal faeces to irrigate such vegetables and fruits has been reported to be responsible for their high rates of contamination with helminth eggs (Guilherme et al, 1999;Takayanagui et al, 2000;Ulukanligil, Seyrek, Aslan, Ozbilge, & Atay, 2001). Considering the fact that a part of the vegetables grown in these developing countries are exported to the developed world, the threat that these contaminations cause to other countries cannot be overlooked (Robertson & Gjerde, 2001).…”

“…Low socioeconomic status, poor hygienic conditions, and lack of sanitary water supplies were reported to be factors that increased the prevalence of infection. Studies have demonstrated advanced contamination of water, soil, and vegetables, and a hazardous circulation between man and the environment [3,21]. In our study, the high rate of amebiasis in group II cases has been attributed to the risk factors present in this geographical region.…”

Prevalence and Importance of Amebic Infestation in Patients with Ulcerative Colitis in Two Regions in Turkey

We investigated the prevalence of amebiasis in patients with ulcerative colitis residing in two geographical regions with different socioeconomic status and climatic conditions, and its effect on the age of onset, duration, localization, and activity of disease. Ninety patients from a high socioeconomic location (group I) and 28 cases from a low socioeconomic location (group II) were enrolled. Median age at disease onset was significantly higher in group I compared with in group II. Prevalence of amebiasis in group I was significantly lower than in group II. A considerably number of patients with amebiasis in group I had a history of travel to the cities with a lower socioeconomic level, mainly located in the east of Turkey. There was a strong relationship between presence of amebiasis and history of travel to eastern parts of Turkey among residents from the northwestern part of Turkey. Median age and age at time of diagnosis were significantly lower in patients with amebiasis compared with those without infection. In patients with mild disease activity, prevalence of amebiasis was significantly lower compared with those with moderate or severe disease activity. In conclusion, prevalence of amebiasis was markedly higher in the southeast compared to the northwest of Turkey. Travel to regions with low socioeconomic status may be considered a risk factor for amebiasis in patients with ulcerative colitis. Amebiasis enhances disease activity in ulcerative colitis.
