ABSTRACT A national survey of the prevalence of intestinal parasitic infections in the Islamic Republic of Iran was made on a random sample of families covered by local health centres affiliated to the medical universities. Out of 53,995 people aged 2+ years, from 12,495 families (0.1% of all families in 1999), 45,128 stool samples were analysed by formalin-ether precipitation. Intestinal parasitic infections were found in 19.3% of the study population (19.7% male, 19.1% female). Giardia lamblia (10.9%), Ascaris lumbricoides (1.5%), Entamoeba histolytica (1.0%) and Enterobius vermicularis (0.5%) were the most common infections. The infection rate was highest in the 2-14 years age group (25.5%) and in rural residents (23.7%).

    • "The prevalence of G. lamblia and E. coli were highest in the B1–12 years age group (P \ 0.05). Sayyari et al. (2005) have been reported that children aged between 2–14 years had high prevalence of intestinal parasite (Hellard et al. 2000). "

    ABSTRACT: The aim of this study was to describe epidemiologic characteristics of intestinal protozoan parasites in a population in Karaj, Iran. Out of 2200 patient, 428 stool specimens (19.45 %) were infected with intestinal protozoan parasites. Out of 428 (19.45 %) infected patient with parasite, 366 (16.63) of patients were infected with single parasite and 62 (2.81) were infected with multiple protozoan parasites. The results were shown that maximum infections belonged to Giardia intestinalis, 31.69 % among the patients with multiple infection and 35.48 % among the patients with single infection. Moreover, Entamoeba coli and Blastocystis hominis were the other common parasites. Other protozoan parasites were as follows: Trichomonas hominis, Iodamoeba butschlii and Endolimax nana. Prevalence of Giardia lamblia and E. coli were highest in the ≤1–12 years age group (P < 0.05). A significant difference was found between protozoan parasites and gender (P < 0.05). Our result indicated that intestinal protozoan infections are still a major public health challenge in this area.

    • "The prevalence of diarrhea among infants under 12 months was reported higher than control [9] , although, some studies showed the lower incidence of Giardia infection in patient with diarrhea [10] [11] . The prevalence of Giardia infection in our country were reported to be about 14% in children and 6% in adults, therefore it should be considered as an important health problem and early detection of infection, appropriate treatment and improvement of health could dramatically reduce the rate of infection [3] [12] . Diagnosis of Giardia infestation is routinely done through classical microscopic-based techniques. "

    • "The results of our study showed that contamination with protozoa was greater than that by helminthes. Similar studies about the prevalence of intestinal parasites were conducted on food handlers, in which some results are the same, and showed protozoan infections were more common than worm infections3,8,24,26,29. One reason for this is that transfer of protozoa is much easier than the transfer of the eggs or larvae of worms13,25. "

    ABSTRACT: Parasitic infection is one of the problems that affect human health, especially in developing countries. In this study, all of the fast food shops, restaurants, and roast meat outlets of Khorramabad (Western Iran) and all the staff employed by them, some 210 people, were selected through a census and their stools were examined for the presence of parasites. The parasitological tests of direct wet-mount, Lugol's iodine staining, formaldehyde-ether sedimentation and Trichrome staining techniques were performed on the samples. The data was analyzed with a chi-square test and logistic regression was selected as the analytical model. The results showed 19 (9%) stool specimens were positive for different intestinal parasites. These intestinal parasites included Giardia lamblia 2.9%, Entamoeba coli 4.3%, Blastocystis sp. 1.4%, and Hymenolepis nana 0.5%. There was a significant difference between the presence of a valid health card, awareness of transmission of intestinal parasites, participation in training courses in environmental health with intestinal parasites (p < 0.05). No statistically significant difference was found between the rate of literacy and gender among patients infected with intestinal parasites (p > 0.05). To control parasitic infection in food handlers, several strategies are recommended such as stool examinations every three months, public education, application of health regulations, controlling the validity of health cards and training on parasitic infection transmission. In this regard, the findings of the present study can be used as a basis to develop preventive programs targeting food handlers because the spread of disease via them is a common problem worldwide.
