“…The prevalence of G. lamblia in the present study is comparable to those reported among institutionalized Thai and Iranian mentally handicapped individuals [33][34][35]. However, a lower G. lamblia prevalence rate of 2.3% (3/133) has been recently reported among institutionalized mentally retarded individuals in southern Iran [36]. It is noteworthy that the prevalence rate of G. lamblia among the mentally challenged is lower than the recently reported rate among pre-school Egyptian children between 2 and 6 years of age (14.8%) in El-Behera, a governorate adjacent to Alexandria [37].…”

Introduction: Concomitant infections with pathogens are common, particularly when there are shared modes of infection or when one pathogen promotes the other. Residence among closed-type care institutions may pose an additional risk of such infections. Mentally challenged patients in rehabilitation centers constitute one of the special needs groups exposed to parasitic infections, including giardiasis. Several studies reported concomitant infection with G. lamblia and H. pylori worldwide and in Egypt; however, the co-existence of these two pathogens among mentally challenged individuals remains unexplored. The present study aimed to study the prevalence and association between G. lamblia and H. pylori among mentally challenged patients in rehabilitation centers in Alexandria, Egypt. Methodology: 200 individuals admitted to four mental rehabilitation centers in the period from June 2013 to January 2014, who guardians gave informed consent, were recruited. Stool samples were collected and subjected to trichrome stain for G. lamblia and to antigen detection for H. pylori. Results: The overall prevalence rates of G. lamblia and H. pylori were 8.5% and 24.0%, respectively. Monoinfection rates were 5.5% for G. lamblia and 21.0% for H. pylori, while concomitant infection with both species was detected in only 3.0% of cases. However, individuals who were H. pylori-positive were about two times more likely to be infected with G. lamblia than those who were H. pylori-negative (12.5% vs. 7.2%). Conclusions: Mentally challenged individuals in Alexandria harbouring H. pylori are about two times more likely to be exposed to G. lamblia. Large-scale studies are recommended to confirm this association.

“…(1 C) showed the isolation of Strongloides stercoralis female which increased significantly in house garden (p=0.0463) and waste dumps (p=0.0463) due to this parasite that is a geohelminth having free-living life cycle in warm humid soil [19]; in addition, this parasite is isolated by two techniques (sedimentation and filter paper technique), but it is showed significance in its isolation by sedimentation technique (0.0463) compared with other techniques because this parasite has greater density than the suspended medium [11]. This result was similar to [20]. Table ( The presence of Ascaris lumbricoides (ova) which appeared in Table (5) and Fig.…”

A study was conducted to determine the prevalence of parasites in soil texture (loam) by using four techniques (salt floatation, zinc sulphate floatation, sedimentation and filter paper technique). During the period from December 2012 to May 2013, 70 soil samples were collected and analyzed from six various sites of Baghdad City such as (house garden, vicinity of house, vicinity of gutter, waste dumps, vegetable farm and hospital garden like Alyarmouk teaching hospital and Central teaching hospital of pediatric). The prevalence of soil parasites was as follows: Toxocara spp. eggs isolated by two floatation techniques (salt and zinc floatation techniques), but this parasite appeared significant in its floatation by salt floatation technique (p= 0.042), while protozoan cysts appeared highly significant in zinc floatation technique (p= 0.00001). In addition, larvae of Strongloides stercoralis showed highly significance in sedimentation and filter paper technique (p=0.0001 and p= 0.001) respectively. Furtherly, female of Strongloides stercoralis appeared significant in its isolation in sedimentation (p= 0.0463), Ascaris lumbricoides (ova) showed highly significant in sedimentation technique (p= 0.0043). These results concluded that the Toxocara spp. eggs more prevelant than other parasites in soil samples, and the soil may play an important role in transmission of zoonotic parasite diseases to human. In addition, the control of high population of animals such as stray dogs and cats is necessary to reduce the distribution of parasites.

“…These differences appear to be attributed to factors such as climate, geographical conditions, socioeconomic characteristics, and the degree of improvements in hygiene and health. While the overall prevalence of S. stercoralis in Iran was 0.03%, one of the studies conducted on mentally-retarded children in the southern and hot area of Bandar Abbas reported 17.31% (3). Similarly, another study on mentally-retarded children in Tehran reported it as 31.6% (7).…”

“…Helminthes are the conduits of soil-transmitted infections and a major health problem. Their most prevalent strains are Ascaris lumbricoides, Trichuris trichura, and the hook worms (13); while their most neglected one is S. stercoralis (3).…”

“…The complex life cycle of parthenogenetic female S. stercoralis enables it to reproduce without participation of a male (4). Most infections are asymptomatic; however, as these infections disseminate, hyper-infection may occur in immunecompromised and immune-deficient individuals, which may result in a fatal disease (3). There are several techniques for detecting larvae in stool samples, one of which is direct smear of feces in saline-lugol's iodine stain, formalin-ethyl acetate concentration, HaradaMori filter paper culture, Bearmann concentration, and nutrient agar plate culture (4).…”

Background: Strongyloides stercoralis causes strongyloidiasis, one of the major parasitic infections in human worldwide. Objectives: This study was carried out to examine the prevalence of S. stercoralis in the state of Lorestan, west of Iran, using a comparative diagnostic approach. Materials and Methods: Stool specimens from a random population sample were examined with light microscope, using direct fecal smear, formalin-ether concentration, and nutrient agar plate culture. Results: The prevalence of S. stercoralis in this study was 0.07%. The statistical random sample in this study was 2839 people whose stool specimens were collected and examined using nutrient agar plate culture. The results showed only two infected persons. The same procedure was administered using direct fecal smear and formalin-ether concentration, which showed no result. Conclusions: As a precautionary measure, a stool test based on nutrient agar plate culture is recommended for detection of S. stercoralis.
