Abstract Background Intestinal parasites (IPs) are widely distributed worldwide and are one of the major contributors to gastrointestinal disease. Their prevalence is associated with poor access to water, sanitation and hygiene (WASH). The objective of this study was to identify the prevalence of IPs, including soil-transmitted helminths (STH), and their relation to socioeconomic characteristics, as well as a first approach to molecularly characterize the types of Giardia intestinalis, Blastocystis spp. and Entamoeba histolytica present in an indigenous community from Puerto Iguazú, Misiones, Argentina. Methods A cross-sectional study was conducted in the rural settlement of Fortin Mbororé between January and March 2018. Socioeconomic variables, household characteristics, and stool and blood samples were collected. Standard coprological techniques were used to analyze stool samples, and a complete hemogram was performed on the blood samples. Giardia intestinalis microscopy-positive samples were genetically typed by the β-giardin (bg) gene. Molecular identification of Blastocystis spp. subtypes and E. histolytica were carried out by amplification and sequencing of a partial fragment of the small subunit ribosomal RNA gene (SSU rDNA). Results The overall prevalence of IPs was 92.7%, with 72.0% specifically for hookworm. IPs were significantly more prevalent in preschool- and school-age children (P < 0.05). No formal education (P = 0.035), the presence of unimproved floors (P = 0.001) and overcrowding (P = 0.005) were significantly associated with IP infection. Hookworm was associated with anemia (P = 0.019). Molecular characterization revealed the presence of E. histolytica sub-assemblages AII (12.5%), AIII (87.5%) and BIV (100%); one case of sub-assemblage D for G. intestinalis; and the presence of subtypes ST1 (14.8%), ST2 (14.8%) and ST3 (70.4%) of Blastocystis spp. Conclusions Protozoans detected in this study are transmitted mainly through water contaminated with fecal matter, evidencing the need to improve the quality of water and sanitation for the inhabitants of Fortín Mbororé. Molecular characterization showed that domestic animals can be implicated in the zoonotic transmission of G. intestinalis and Blastocystis spp. to humans. A hyperendemic area for STH was found, with hookworm prevalence greater than 50%. Therefore, improvements in WASH as well as mass deworming programs need to be implemented in this area to control and decrease the prevalence of IPs in general and STH in particular.

A total of 200 stool samples were examined and five species of intestinal parasites were identified. Two of them were protozoans (Entamoeba histolytica and Giardia intestinalis) and the rest of which three species were nematode parasites (Ascaris lumbricoides, Trichuris trichiura and Strongyloids stercoralis). The overall prevalence of parasitic infection was 50%. Individually the prevalence of Ascaris lumbricoides, Entamoeba histolytica, Giardia intestinalis, Trichuris trichiura and Strongyloids stercoralis was 25%, 13%, 6%, 3.5% and 2.5%, respectively. Patients of different age and sex had a variable degree of infection. Children aged under ten years showed the highest prevalence (73.97%) compared to other groups. Accordingly, male patients were found slightly more susceptible to the infection (50.38%) compared to the female (49.29%). People belonging to different occupation and educational qualification had various degree of infection. As expected patients who had no education and poor monthly income, showed the highest prevalence of infection, 77.77% and 90%, respectively. Personal hygiene practices of the patients had much influence on the parasitic prevalence and rate of infection. Respectively 58.82%, 91.42%, 80% and 63.55% prevalence were found among the patients who used to drink unsafe water, wash hands without soap, stay barefooted most of the time and do not trim their nails regularly. The present study supposed to reveal that socioeconomic conditions and behavioral factors may influence the prevalence of parasitic infections. Bangladesh J. Zool. 47(1): 129-136, 2019

The present study evaluated the frequency of intestinal parasitoses in children in public day care centers applying parasitological and immunological diagnostic methods. Fecal samples from 121 children from six public daycare centers were analyzed using parasitological techniques. Epidemiological data were obtained through a questionnaire, where parents and / or guardians were asked, for instance, whether the children had contact with soil, ate raw food, such as vegetables or raw or undercooked meat, normally walked around barefoot or had contact with animals. Fecal samples from 82 children were also tested for Giardia intestinalis and Cryptosporidium sp. coproantigen using the enzyme-linked immunosorbent assay (ELISA) which was also used for Entamoeba coproantigen detection only in samples that tested positive for the parasite by parasitological stool exam/optical microscopy. Intestinal parasite infection was noted in 23.1% (28/121) of the children. The most frequent parasite was Giardia intestinalis (13.2%), followed by Entamoeba coli (5.8%), Blastocystis spp. (1.7%), Endolimax nana (1.7%), Enterobius vermicularis (1.7%), Cystoisospora belli (0.8%),Entamoeba histolytica/E. dispar complex (0.8%), and Ascaris lumbricoides (0.8%). Positivity for parasite infection using parasitological stool exams was significantly associated with age groups, with a higher frequency in 4 to 6 year old children (p=0.03). No association or significant variations were noted in the prevalence of intestinal parasites in relation to the epidemiological variables studied. All samples were negative for Cryptosporidium sp. and Entamoeba histolytica detected by immunological testing, and 17.1% (14/82) children tested positive for Giardia intestinalis, although using parasitological exam/optical microscopy, only 14.6% (12/82) tested positive. The high incidence of intestinal parasites, especially protozoans, suggests probable interpersonal transmission among the children, environmental contamination, or even contaminated food/water intake. Thus, consolidation of preventive measures and efficient diagnostic resources as well as control of intestinal parasites and patient treatment are of utmost importance.

Background:: Intestinal parasitic infections are one of the most common infections in humans, particularly in re-source-poor communities. Gastrointestinal parasites, specially protozoa can lead to diarrhea, malabsorption, and anemia. The majority of parasitic diarrhea is caused by Entamoeba histolytica, Giardia duodenalis, and Cryptosporidium spp.. The present study aimed to evaluate the prevalence of intestinal parasites among diarrheic patients referred to the Shahid Rajaee Polyclinic, Ahvaz, southwestern Iran. Methods:: A cross-sectional study was conducted to determine the prevalence of intestinal parasites among 250 diarrheic pa-tients using direct smear, formalin-ether concentration, ziehl- neelsen, and trichrome staining. Results:: The results indicated that 34.4% (86/250) of the patients were infected with pathogenic parasites. Giardia duode-nalis with an occurrence of 18.8% (47/250) and Cryptosporidium spp. with a frequency of 2.8% (7/250) had the highest and lowest infection rates, respectively. Blastocystis hominis with a frequency of 15.2% (38/250) showed the highest prevalence rate after G. duodenalis. Entamoeba histolytica/dispar was observed in 3 (1.2%) of diarrheic patients. The age group 1−10 years old was the most frequently infected group (27.9%). We could not find a significant association between the source of drinking water and intestinal parasitic infections (p= 0.912). Conclusions:: This study demonstrated that G. duodenalis was the predominant parasite found among the patients. The re-sults revealed that intestinal parasites were one of the main health problems in the region.

In general, school-age children are the most vulnerable to parasitic infections and are particularly exposed to multi-parasitism and its potential consequences. This study aimed at determining the intensity of multi-parasitism in Nyong et Mfoumou Division. A cross-sectional study took place from September 2017 to July 2018 among pupils of five (05) government schools from the Nyong et Mfoumou Division. Stool samples were collected from each child and examined for protozoan cysts, helminth eggs and larva while blood samples were collected for detection of Plasmodium sp. and filarial blood stages. In addition, socio-demographic information were documented. In total, 416 schoolchildren were recruited; out of which 309 (74.28%) were infected by at least one parasite species. 13 parasite species were found: 03 blood parasites and 10 intestinal parasites. Plasmodium falciparum was the main blood parasite (37.26%). Amongst intestinal parasites, Entamoeba coli were the most common among protozoa (29.33%) and Ascaris lumbricoides among helminths (21.39%). The frequency of multi-parasitism was 44.47% and the average species reach was 1.43 ± 0.01 per individual. Four types of multi-parasitism were found (bi-parasitism, tri-parasitism, quadri-parasitism and penta-parasitism); the bi-parasitism (26.68%) was the most common. Significantly statistic associations were found between parasite species such as: Entamoeba coli, Entamoeba histolytica/dispar, Ascaris lumbricoides, Trichuris trichiura can be explained by the same means of transmission. Association between Ascaris lumbricoides and Mansonella perstans could be a synergic interaction between these parasites. We conclude that the intensity of multiparasitism among schoolchildren in Nyong et Mfoumou Division is high with predominance in rural areas.
