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: Parasitic gastroenteritis is one of the most common illnesses in humans worldwide. Most studies on gastroenteritis have focused on viral and bacterial infections, while parasitic enteropathogens and especially intestinal protozoan parasites may play a role that has not been well studied. The aim of this study is to identify the prevalence of enteropathogenic parasites and sporozoan protozoa in patients with gastroenteritis in selected hospitals in seven provinces of Iran. Methods: In this cross-sectional study, randomly 4200 stool specimens were obtained from patients with gastroenteritis in selected hospitals. Primarily samples were examined directly for enteroparasites. The samples were filtered and concentrated by using the Paraseb Kit; and fixed, and stained by different methods including acid-fast staining, Auramin phenol fluorescence staining, and Giemsa staining were observed using light microscopy under various magnifications. Results: The results revealed the overall rate of parasitic infection was 2.4% in the studied population. The highest rate of infection was observed in the 0-10 year age-group (47.2%). Among the infected patients, 59.5% were male and the rest were female patients.Annual Research & Review in Biology. 07/2014;

ABSTRACT: Parasites and parasitic diseases are widely spread in the world. Their adverse effects on health and social-economic society cause tremendous public health problems. Parasitic infections in different ways (water, soil, food and vegetables) can affect humans and induce other complications such as gastrointestinal disorders, malnutrition, anemia and allergies and sometimes even life threatening. Medicinal plants are being widely used, either as a single drug or in combination with synthetic drugs. These medicinal plants are considered as a valuable source of unique natural products and drugs for development of medicines against various disorders and diseases. In this article the recently published papers about medicinal plants and parasites were reviewed, using scientific sites such as Medline, PubMed and Google Scholar. The used terms included: herbal medicine, medicinal plants, and antihelmintic drugs, antinematoda, anticestoda, antitrematoda. From the above collected literature it might be concluded that these plants are promising potential sources for preparation of new drugs or for pharmacological and therapeutic applications.Asian Pacific Journal of Tropical Medicine 09/2014; 7:S29–S33. · 0.50 Impact Factor
