“…In the present study, the most common intestinal parasites were B. hominis and G lamblia,, which is similar to the results reported by Kia et al (2008) and Daryani et al (2012) in Mazandaran province [12,14]. B. hominis is the microscopic parasitic organism found throughout the world [20].…”

“…The overall prevalence of parasites infection was 14.2% in the current study. In the previous studies conducted on specific community groups in Mazandaran province, the prevalence rates of IPIs were reported to be 15.5%, 26.2%, 33.3%, and 12% in the food handlers, mentally challenged children, school children, and rural inhabitants, respectively [11][12][13][14].…”

“…Given the diversity of climatic conditions, economic status, local traditions, and social factors in the different regions of Iran, the implementation of epidemiological surveys in various locations can provide a useful basis for planning and controlling the parasitic infections. The previous studies performed in the north of Iran were focused on the prevalence of IPIs in specific community groups, such as school children, food handlers, intellectual disability children, and rural communities [11][12][13].…”

Introduction: Intestinal parasitic infection (IPIs) is one of the most important health problems in the developing countries. Study on the prevalence of IPIs in various communities is a prerequisite for the development of appropriate control strategies. The aim of this study was to evaluate the prevalence of intestinal parasites among the general population in Mazandaran province, northern Iran. Methodology: This study was conducted on 4,788 specimens collected from 17 urban areas (2,515 samples) and 34 rural areas (2,273 samples) within January-December 2016. Fecal specimens were examined by direct wet mounting, formalin-ether concentration, modified ZiehlNeelsen, and trichrome staining methods. Results: The overall infection rate of intestinal parasite was 14.2% (680/ 4,788). Blastocystis hominis and Giardia lamblia were identified as the most frequent parasites. Protozoa, helminths, and polyparasitism (co-infections with two or more parasite species) were observed in 12.3%, 1.03%, and 0.85% of the specimens, respectively. Furthermore, IPIs showed a significant association with household income, place of residence, washing of vegetables, exposure to soil and season (p < 0.05). Conclusions: Based on the findings, parasitic infections are still a major public health concern in the north of Iran that requires special attention. Therefore, the major key to success in the prevention of IPIs is the execution of some interventions, including patient screening and treatment, public education, and improvement of sanitary conditions.

“…It was associated with diarrhea in the tropics and subtropics, since it was found in patients throughout the world. The reported prevalence rates of intestinal protozoa varied from 1.5% to 10% in developed countries, with much higher rates of 30%to 50% in developing countries [9,10].…”

“…Sharif et al reported 26.2% infection of intestinal protozoans (19) and Daryani et al reported 33.3% infection rate (20) in the North of Iran and Assmar et al (1999) reported that the rate of parasitic infection in 6252 pupils in Mazandaran province was 57.1%, which may be associated with poor sanitation, low education and drinking water contamination (21)(22)(23). A recent study by Kousha et al (2011) in Tabriz, Northwest of Iran, reported 44% infection by one or more intestinal parasites in school children (18).…”

Background: Sporozoan protozoa and enteroparasites cause gastroenteritis. Sporozoa are the major cause of self-limiting diarrhea in immunocompetent patients, however they cause serious diseased in patients with immunosuppression. Objectives: The current study aimed to identify the prevalence of sporozoa and enteroparasites among patients with gastroenteritis referred to the healthcare centers in seven provinces of Iran. Patients and Methods:In this cross-sectional study, 4200 stool samples were randomly collected from patients with gastroenteritis in the selected hospitals of Gilan, East Azerbaijan, Qazvin, Kurdistan, Mazandaran, Tehran and Khorasan-e-Razavi provinces. Primarily samples were examined directly for enteroparasites. The samples were then filtered and concentrated using Paraseb kit. The pellets were fixed, stained by different assays including acid fast staining, Auramin Phenol Fluorescence, Giemsa and light microscopy. Results:The results revealed the overall rate of infection, 3.86% (163 cases), as an indicator of parasitic enteropathogens in Iran. Among the provinces, Khorasan-e-Razavi and Mazandaran with 8.83% (53 cases) and 0.34% (2 cases) showed the highest and lowest rates of infection, respectively. The frequencies of sporozoa including Cryptosporidium, Microsporidium, Isospora and Cyclospora spp. were 0.1%, 0.1%, 0.07% and 0.02% respectively. Among the parasites, Giardia lambelia, Taenia saginata and Hookworms with 1.78% and 0.02% had the highest and lowest rates of infection, respectively. Regarding the age groups, the highest and the lowest rates of infection were in 0 -10 (48%) and 41 years old and above (6.7%) groups, respectively. Conclusions: Despite relatively low prevalence of sporozoa, giardiosis is the most prevalent agent for gastroenteritis amongst 3.86% of parasitic infections in Iran. The current study confirmed the abundance of infection in warm and wet seasons, and more frequency of infections among children than adults. Meanwhile, geographical and agricultural conditions, seasonal rainfall, abundance of water, and animal contact are key factors affecting sporozoan infections.
