“…There is a highly significant difference between infected and non-infected children regarding residence where most of the infected children were rural residents (61.1%). Similar findings were observed in other Egyptian studies [15,23,31]. Rural children mostly have risky behavior such as walking poor footed, water and domestic animal contact, poor fingernails and hand hygiene, and defecation in the open agricultural field which consequently leads to more soil contamination with parasites [15].…”

“…However, there is no significant gender difference regarding IPIs (P=0.5). There were variable findings between Egyptian studies regarding gender differences where some studies [22,23,27,28,31] revealed similar findings with insignificant gender differences while other studies [21,25,29,30] revealed significant gender differences. However, despite this variability, all of these studies except one [25] revealed a higher prevalence of IPIs among male students.…”

“…This can be attributed to the unsanitary environmental conditions and low level of public awareness [19]. Egyptian studies conducted on school children revealed marked variability regarding the prevalence of IPIs with an infection range from 22.4 to 63.8% [15,[20][21][22][23][24][25][26][27][28][29][30][31].…”

Background Intestinal parasitic infections are still representing a significant health problem in developing countries including Egypt. School children are highly vulnerable to this type of infection, and they suffered many health consequences. This study was conducted to identify the prevalence of intestinal parasitic infection among school children and its related factors. Results This is a school-based cross-sectional study conducted on 726 school children selected from primary, preparatory, and secondary schools located at Aga district, Dakahlia governorate. A questionnaire sheet including data on the socio-demographic characters of students and their families, environmental and behavioral variables, and gastro-intestinal symptoms was filled. Also, fresh stool samples were collected from each child for microscopic examination to detect eggs, cysts, and trophozoites of intestinal parasites. There were 239 of 726 children with IPIs representing an overall prevalence of 32.9%. The most prevalent parasitic species were E. histolytica (12.3%), G. lamblia (8.5%), H. nana (7.7%), and A. lumbricoides (5.7%). There were significant differences between infected and non-infected children regarding age, educational stage, residence, monthly family income, and maternal education levels. Also, there were highly significant differences between infected and non-infected children regarding all environmental and behavioral variables and the occurrence of GIT symptoms. Conclusion High prevalence of IPIs among school children indicates little personal hygiene and poor environmental sanitation. Much more efforts are needed for the application of proper prevention and control strategy.

“…Additionally, two studies [31,32] observed that infections with H. nana and E. vermicularis were the most reported enteric helminthic infections. This finding of high prevalence of intestinal parasites is consistent with recent studies conducted in Egypt, reporting a 30.7% rate of IPIs among school-children in Damietta [6] , 31% in Aswan [7] ; in contrast, a much higher prevalence (60%) was reported in a study conducted in Greater Cairo in children under the age of 12 [5] . The difference in prevalence of intestinal parasitism may be explained by variances in sample size, geographical areas and the diagnostic methods used.…”

“…Notably, IPIs are among the most frequent infections worldwide, particularly in developing countries like Egypt, and continue to be a public health concern [4] . In Egypt, various prevalences of IPIs were recorded, reaching as high as 60% for children 12 years and under [5][6][7] . Cryptosporidium is an obligatory intracellular protozoan parasite that infects the gastrointestinal tract (GIT) and is a leading cause of GIT morbidity and a top cause of mortality due to diarrhea for preschool children under the age of five in developing nations [8,9] .…”

Background: Diarrheic children are more vulnerable to a variety of pathogens including gastrointestinal parasites. Cryptosporidiosis is a major etiology of chronic diarrhea in Egyptian children; it has both shortand long-term consequences for their growth and development.Objective: The purpose of this study was to determine in a cohort of children with diarrhea the prevalence of Cryptosporidium spp., molecularly; and other intestinal parasites, coproscopically, and to assess the association between Cryptosporidium and patient characteristics. As well as to evaluate the usefulness of molecular assay in detection of cryptosporidiosis in diarrheic children. Subjects and Methods: Fecal specimens were collected from 102 diarrheic Egyptian children, aged 12 years and under. All fecal specimens were examined coproscopically by wet mount prior to and after concentration, as well as permanent staining with modified acid-fast (MAF) for detection of intestinal parasites. Molecular assay using nested PCR (nPCR) was performed for detection of Cryptosporidium oocyst wall protein (cowp) gene. The association of patient demographics and clinical data with detection of Cryptosporidium spp. was determined. Results: Cryptosporidium copro-DNA was detected in 12 (11.8%) cases, for 5 (4.9%) of which oocysts were detected by MAF coproscopy; 9 cases of E. histolytica complex and 7 cases of G. intestinalis were detected by coproscopy. Other than the measure of head circumference, none of the patient characteristics had a significant association (P=0.027) with the detection of Cryptosporidium. Conclusion: There is a clear predominance of intestinal protozoa in diarrheic children, and Cryptosporidium spp. was the major enteric pathogen. Molecular assay should be included for the routine laboratory diagnosis of cryptosporidiosis.

In developing countries, the prevalence of intestinal parasitic infection is still significant, particularly due to geographical and socioeconomic variables. The objective of this study was to map the distribution pattern of intestinal parasitic infection in a cohort of the Egyptian population, as well as to assess associated risk factors. A cross-sectional hospital-based study was conducted on 386 patients. A single fecal specimen was collected from the study individual and examined microscopically for the detection of parasitic infection. DNA was extracted from all samples and utilized to amplify Entamoeba histolytica complex species, Cryptosporidium species, Giardia intestinalis assemblages, and Blastocystis species using PCRs. Typing of Cryptosporidium species and Giardia intestinalis assemblages was performed using restriction enzymes RasI and HaeIII respectively. While Blastocystis spp. subtypes (ST) were identified through sequencing of PCR products and phylogenetic analysis. 59.6% (230/386) of the study patients were infected with one or more intestinal parasites, 87.4%; 201/230 of patients had mono-parasitic infections, and 12.6%; 29/230 had multiple-parasitic infections (P < 0.0001). The predominant protozoa were Blastocystis, followed by Entamoeba histolytica complex, and Giardia intestinalis both as mono-parasites and as part of multiple parasites. Molecular assays showed that Blastocystis ST3, Entamoeba dispar, Giardia intestinalis assemblage B, and Cryptosporidium hominis were the most prevalent species. Intestinal parasitic infection was significantly associated with age, gender, residence, and water source. Multi-parasitism showed that residency in a rural area was a risk factor (OR 4.49; 95% CI 1.51–13.37; P = 0.007). Egyptians residing in rural areas have a high prevalence of intestinal multi-parasitism. Therefore, to lessen the prevalence and effects of these infections in this group, effective and sustainable control methods, providing health education focusing on good personal hygiene habits, and providing a safe drinking water supply should be implemented.
