Prevalence of intestinal parasitic infections in the Islamic Republic of Iran.
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%).

ABSTRACT: Infection with Trichostrongylus spp. is common among human and herbivorous in most parts of Iran, especially in southern and northern areas. The aim of present study was to identify Trichostrongylus spp. among human population using excreted egg specimens, by the molecular method, in Mazandaran Province, northern Iran. Overall, 33 positive fecal specimens were randomly sampled and examined. PCR amplification of ITS2-rDNA region was performed on the isolated egg and then a restriction fragment length polymorphism (RFLP) profile was considered to discriminate of Trichostrongylus spp. A total of 33 positive fecal specimens, 29(78.9%), 4(12.1%) were found T. colubriformis and T. axei respectively. Our data appear the molecular evidence of both human T. colubriformis and T. axei infections in North of Iran. T. colubriformis was the probable most common zoonotic species causing human trichostrongylosis infection in the area.Iranian Journal of Parasitology 02/2015; 10(1):110-115. · 0.87 Impact Factor

ABSTRACT: Parasitic infection is highly prevalent throughout the developing countries of the world. Food handlers are a potential source of infection for many intestinal parasites and other enteropathogenic infections as well. The aim of this study was to determine the prevalence of intestinal parasite carriers among food handlers attending the public health center laboratory in Sari, Northern Iran for annual check-up. The study was performed from August 2011 through February 2012. Stool samples were collected from 1041 male and female food handlers of different jobs aged between 18 to 63 years and were examined following standard procedures. Sociodemographic, environmental and behavioral data analysis of the food handlers were recorded in a separate questionnaire. Intestinal parasites were found in 161 (15.5%) of the studied samples. Seven species of protozoan or helminth infections were detected. Most of the participants were infected with Giardia lamblia (53.9%) followed by Blastocystis hominis (18%), Entamoeba coli (15.5%), Entamoeba histolytica/dispar (5.5%), Cryptosporidium sp. (3.1%), Iodamoeba butschlii (3.1%) and Hymenolepis nana (1.9%) as the only helminth infection. The findings emphasized that food handlers with different pathogenic organisms may predispose consumers to significant health risks. Routine screening and treatment of food handlers is a proper tool in preventing food-borne infections.Revista do Instituto de Medicina Tropical de São Paulo 03/2015; 57(2):139-44.

ABSTRACT: In this study, the result findings of the current study indicated that out of 216 children including 120 male children and 96 female children participated in the study, 167 children were found positive with various intestestinal worms. The frequency of worm infestation was found 77.31%. Among them the positive worm infestation was more in female children (64%). Out of 167 positive subjects, Ascaris lumbricoides frequency 53.29% was highest among all other worms and was present in both single and mixed infestations. Similarly, a bit high frequency was also noted in case of for Hymenolepis nana 20%, Trichuris trichura 10% and lowest frequency was noted in Taenia saginata (0.59%). However, most of the positive cases showed single infestation as compared to only 06 cases (3.59%) of mixed infestation.
