Background. In tropical countries, intestinal protozoal parasitic infections are among the common infections causing significant morbidity and mortality. Thus, the present study was conducted to assess the status of intestinal protozoal parasitic infections among diarrheal patients attending Negelle Borena General Hospital and investigate the possible risk factors for the infection. Methods. A case-control study design was employed in the study. The intestinal protozoal parasites were detected using a wet-mount, stool concentration, and modified Ziehl–Neelsen methods. The crude and adjusted odd ratios were considered to identify the associated risk factors for intestinal protozoal parasitic infections among the study participants. Results. The overall status of parasitic infection was 46.88% in cases and 27.08% in the control groups. The most prevalent protozoal infection was Giardia lamblia (9.38%) and followed by Entamoeba histolytica/dispar (6.25%) in the cases. The highest preva...

The aim of this study was to identify common stool parasites in patients attending a tertiary care centre in South India. We evaluated 2355 stool samples and parasites were detected in 7.9% of samples. 41.1% of our patients were in the 45-58-year age group. Protozoal infections were the commonest seen in 7.8% of samples. Entamoeba histolytica was the commonest protozoa (4.6%) followed by Entamoeba coli (1.2%) and Giardia (0.8%). Entamoeba histolytica and Entamoeba coli were together seen in 0.63%, and they were the commonest organisms seen in samples with multiple-organism infection. Both were equally detected in diarrheal samples.

Objectives: The objectives of the study were to find out the prevalence and spectrum of intestinal parasitic infestations among the patients attending the associated hospital with complaints of abdominal pain and diarrhea. Methods: A total of 117 stool samples were collected and screened for intestinal parasitic infection. Plastic containers with identification numbers were given to the patients, and information regarding name, age, sex, ward, and findings of stool routine microscopy were recorded. All samples were examined macroscopically for appearance, color, and the presence of blood and mucus then analyzed using direct microscopy for the presence of intestinal parasites. Results: It was found that intestinal parasitic infections were mainly attributed to Entamoeba histolytica, Ascaris lumbricoides, and Giardia lamblia which are pretty prevalent in the region of the study. Conclusion: It was found that intestinal parasitic infections were mainly attributed to E. histolytica, A. ...

This study was designed to determine the prevalence of intestinal parasites in relation to personal and environmental risk factors in Bursa province of Turkey and to compare wet mount + Lugol's iodine, formalin ethyl acetate concentration, trichrome staining and enzyme-linked immunosorbent assays (ELISA) methods used in Entamoeba histolytica/ Entamoeba dispar diagnosis. For this purpose a total of 176 faecal samples from people were randomly collected from regions of the Bursa City Centre, where crowded families of low socioeconomic levels reside. All faecal samples were examined by wet mount + Lugol's iodine formalin ethyl acetate concentration, trichrome staining methods and ELISA. 66 faecal samples were infected with one or more parasite species and the overall prevalence rate was 37.5%. Nine species of intestinal parasites, including six protozoon and three helminth species were found. The most prevalent species was Blastocystis hominis (17.04%) and others were found with the following frequencies: 9.09% Enterobius vermicularis, 7.38% Giardia intestinalis, 5.68% Entamoeba coli, 2.27% E. histolytica/E.dispar, 1.13 % Entamoeba hartmani, 1.13% Taenia spp., 0.56% Hymenolepis nana. 6.2% of examined samples had mixed infections. Overall prevalence of the detected parasites did not differ significantly in different demographic groups. Except for B. hominis and G. intestinalis, there was no evidence for sex, age and other demographic-related differences in the prevalence of these parasites. Statistically, B. hominis and G. intestinalis were higher in 20 to 49 and in 1 to 19 year age groups, respectively than in any other age group. Microscopical examination and ELISA revealed that one sample (0.5%) was found to be positive using all 4 methods, and 162 samples (92%) were found to be negative with all 4 methods applied. E. histolytica/E. dispar complex was detected in 0.56% (1); in 0.56% (1), in 0.56% (1) and in 2.27% (4) of the fecal samples examined by wet mount + Lugol's iodine, formalin ethyl acetate concentration, with trichrome staining, and ELISA respectively. The wet mount + Lugol's iodine, formalin ethyl acetate and trichrome staining methods had a sensitivity of 25% each, a specificity of 94.1, 99.4 and 98.2%, compared to the results of the E. histolytica/E. dispar ELISA, respectively.

Objective: Intestinal parasitic infection is a burgeoning health issue, especially in developing countries owing to low socioeconomic conditions, poor sanitation, poor personal hygiene, and lack of access to potable drinking water. This study aims to determine the prevalence of different intestinal parasites among the patients. Methods: This cross-sectional study was conducted among 470 patients attending our hospital from October 2018 to September 2019. Specimens were collected and examined macroscopically and microscopically using concentration methods and modified Ziehl-Neelsen staining for coccidian parasites. Results: Out of the 470 patients, prevalence of intestinal infections was 4.89%. The helminthic infections were more common (52.17%), which was topped by Hookworm infection (26.09%) followed by Ascariasis (13.04%). Among the protozoa, Giardia lamblia (26.09%) was the most common, followed by Entamoeba histolytica (17.39%). The parasitic infections were more in female (5.62%) than male (4.19%) and highest in the pediatric age group and between 51 and 60 years. Conclusion: The prevalence of intestinal parasitic infections is decreasing due to increasing awareness about sanitation, effects of open defecation, safe drinking water, and personal hygiene. However, the need of intervallic monitoring of intestinal parasitic infections is necessary.
