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

Solid waste produced by modern society, together with lack of basic sanitation and poor hygiene practices result in risks to public health. 46 workers from the cities of Pelotas, Canguçu, Morro Redondo, Rio Grande and Capão do Leão were evaluated by parasitological examination of two fecal samples by Ritchie, Hoffman, Pons and Janer- HPJ techniques and Sheather method as well as a consented interview. 47.8% (22/46) of the examined individuals were parasitized, with no significant difference between both groups (garbage dump and recycling volunteers). Most of the samples evaluated presented forms of helminths (68.2%) while protozoa were found in 31.8% of the samples. Helminths found, and their respective prevalence were: Ascaris lumbricoides (31.8%), Ascaris lumbricoides/Trichuris trichiura (18.2%), Trichuris trichiura (9.1%), Taenia sp (4.6%) and Trichuris trichiura/Ancylostomids (4.6%). Protozoa were: Giardia intestinalis (13, 6%), Entamoeba spp. (9.1%) and Endolimax nana (9.1%). Monoparasitism was observed in 77.3% of the cases. Most of the population consisted of women, 21-40 years of age, low educational level and monthly income less than one minimum wage. The majority of the workers did not use protective equipment. Multivariate analysis revealed that infection from parasites in scavengers who lived near open sewers was 6.65 times higher (p = 0.0065) than in the other workers. In the localities studied, our results showed that the risk of acquiring parasitic infections was related to poor sanitation and the lack of sewerage systems; and not actually due to handling these types of waste. The parasitological indices found are similar to those described previously in other parts of the country.

Introduction: The parasites can cause different gastrointestinal disorders which have great impact on life quality. Hearing and speech impaired children are unable to maintain proper sanitation, making them more prone to intestinal parasitic infection. Aim and Objective: To know the prevalence of various parasitic infestations among hearing and speech impaired Children. Materials and Methods: Stool specimen were collected from 104 hearing and speech impaired children who were living in private rehabilitation school of chisapani village of Banke district Nepal for a period of 5 month from December 2017 to April 2018 and direct wet mount was prepared using normal saline (0.9%) and Lugol's iodine (0.5%). The wet mount was observed under microscope for parasites. Results: Among 104 individuals intestinal parasites were seen in 25.96 % of students. Giardia lamblia (37.04%) was the most common parasite followed by Ascaris lumbricoides (18.52%) and Entamoeba histolytica (14.82%). Conclusion: The study shows that although the speech and hearing impaired children are more prone to parasitic infection, the prevalence is same as normal people. Giardia lamblia, Ascaris lumbricoides and Entamoeba histolytica were the common parasites. Prompt diagnosis and treatment of infected children should be undertaken.

Abstract Background: Intestinal parasitic infections are the most common infections in the developing world. Globally, out of the 1.5 billion annual cases of diarrhea, about 70% or 1.05 billion cases are thought to be caused by biological contamination of food. In Ethiopia, due to poor environmental sanitation, low awareness about personal hygiene, lack of pure potable water, and improper faecal disposal, intestinal parasitic infections are highly prevalent. Thus, the aim of this study was to determine the prevalence and associated factors of intestinal parasitosis among food handlers working in food and drinking establishments in Ginnir town, southeast, Ethiopia.Methods: Cross-sectional study design was employed from May 1 to May 29, 2014 in food and drinking establishments in Ginnir town. A total of 348 food handlers were enrolled and stool specimens were collected, and examined using direct saline and formol-ether concentration methods. Bivariable and multivariable logistic regression analysis was performed. A P-value <0.05 was considered as an indicator of statistical significance.Results: The overall prevalence of intestinal parasitosis among food handlers was 48/348 (13.8%) [95%, CI=6.8-20.6]. Entamoeba histolytica/dispar 23/348 (6.6%) followed by Giardia lamblia 16/348 (4.6%), Ascaris lumbricoides 7/348 (2.0%) and Strongyloides stercolaris 2/348 (0.6%) were the detected parasites. Moreover, amongst positives for intestinal parasites, comparable proportions of parasites were detected in males (52%) and females (48%). Habit of eating raw/under cooked vegetables (p=0.00; aOR=2.60; 95%, CI=1.94-8.67), hand washing habit before eating (p=0.03; aOR=1.22; 95%, CI=1.01-3.89), hand washing habit after visiting toilet (p=0.01; aOR=2.85; 95%, CI=2.06-8.31), hand washing habit before food preparation (p=0.02; aOR=1.85; 95%, CI=1.27-4.34) and poor personal hygiene (p=0.00; aOR=3.39; 95%, CI=1.51-10.23) were factors associated with intestinal parasitic infections.Conclusions: The prevalence of intestinal parasitosis among food handlers was relatively low. Though the prevalence was low; regular medical check-up, training and health education on safe food handling and processing should be given to all food handlers.

Aims: Vegetables are usually exposed to parasitic ova, larvae or oocyst during cultivation, irrigation, storage, transportation or while processing for consumption. Consumption of raw, unwashed and improperly cooked vegetables is considered a risk factor for transmission of intestinal parasites. This study assessed the parasitic contamination of vegetables and also determined factors associated with parasitic contamination of vegetables in selected markets in Calabar, Cross River State. Place and Duration of Study: Sample: Markets within Calabar, Cross River State, Nigeria between September and October, 2018. Methodology: A pre-tested semi-structured questionnaire was used for collecting data on factors associated with parasitic contamination of vegetables. 300 vegetable samples were purchased and processed from three different markets in Calabar for examination of parasitic contamination using direct wet mount and zinc sulphate floatation techniques. Results: 15.7% (47/300) of the vegetables sampled were positive for at least one parasite. The species and stages of parasites detected were larvae of Strongyloides, ova of Trichuris trichiura and Hookworm, and cysts of Entamoeba histolytica and Giardia lamblia. Larvae of Strongyloides (11.3%) were the most frequently detected followed by ova of T. trichiura (1.7%) and Hookworm (1.7%) (P = 0.000). Among the five vegetable types sampled, waterleaf (40%) had the highest level of parasitic contamination followed by pumpkin (21.7%). Washing vegetables before display and the means of display were significantly associated with parasitic contamination (P = 0.000). Conclusion: Prevention of contamination is important in reducing food-borne parasitic infections and can be achieved through improved personal hygiene practices of farmers, vendors and consumers, proper washing of vegetables and improved sanitary conditions especially around markets where these vegetables are sold.

Stool samples from 122 children from urban slum (n = 72) and rural (n = 50) areas were analyzed using multi-parallel real-time qPCR to determine the prevalence of intestinal parasites from two communities in Colombia. Findings indicated a prevalence of 86.1% Blastocystis spp., 62.5% Giardia intestinalis, 19.4% Cryptosporidium spp., 19.4% Ascaris lumbricoides, and 5.6% Trichuris trichiura in an urban slum; and 76% Blastocystis spp., 68% Giardia intestinalis, 20% Entamoeba histolytica, 50% Ascaris lumbricoides, 46% Trichuris trichiura and 2% Strongyloides stercoralis in rural areas. Polyparasitism was higher in rural (58%) compared to urban (25%) areas (p = 0.001). Trichuris trichiura burden was higher in the rural area (p = 0.002). Over 40% of helminth infections in rural areas had a heavy parasite burden by WHO classification. Over half of urban and rural children were infected with Giardia intestinalis and Blastocystis spp. Our data provides accurate epidemiologic surveillance for public health interventions.

Intestinal Parasitic Infections

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.

 Intestinal parasitic infestation reflects a health threat with patients living with HIV & Tu-berculosis (TB). Parasitic infections caused by protozoa and helminths are the most com-mon infections worldwide. The present study was done to find out the frequency of intes-tinal parasitosis among HIV and Tuberculosis (TB) patients of Dharan total of 53 samples (>15 years) from HIV seropositive patients and 28 samples (>20years) from TB patients were collected in a clean, dry and capped fitted container and subjected to macroscopic and microscopic examination for ova, cyst, adult parasites and or segments of parasites. Stool samples were fixed in a 10% formalin-ether solution. Sedimentation technique, with modified acid-fast (Ziehl-Neelsen) staining method, was performed for opportunistic in-testinal parasites in both patients. Multi-parasitic infection was noted in the study. The overall prevalence of intestinal parasites was found to be 54 (66.67%). This result had shown that the participation of male patients was comparatively higher than female pa-tients. Out of 81 stool samples, 15 (27.78%) G. lamblia, 12(22.22%) E. histolytica, 12 (22.22%) Cryptosporidium parvum, 6 (11.11%), Isospora belli 4 (7.40%) Microspridium, 1(1.85%) Blastocystis hominis, 2(3.70%) and Taenia spp, 2(3.70%). To prevent this infec-tion appropriate health education should be given to the patients concerning disease trans-mission, antiparasitic therapy, personal hygiene, and safe drinking water.

Introducción: el diagnóstico de estrongiloidiasis se realiza de rutina en los laboratorios clínicos; sin embargo, su detección se dificulta debido a la baja excreción parasitaria y la baja sensibilidad de las pruebas parasitológicas empleadas. Objetivo: diseñar y estandarizar una PCR en tiempo real (qPCR) para la detección de ADN de Strongyloides stercoralis en muestras de materia fecal. Materiales y métodos: se establecieron las condiciones de qPCR y se evaluaron: a) la especificidad analítica mediante análisis BLASTn de secuencias obtenidas de muestras positivas para Strongyloides stercoralis, b) sensibilidad analítica mediante diluciones seriadas de muestras que contenían larvas de Strongyloides stercoralis y c) la ocurrencia de reacciones cruzadas con otros parásitos e inhibidores de la amplificación. Resultados: se amplificó un fragmento de 101 pb del gen 18S del ARN ribosomal. El valor de Ct osciló entre 23 y 29, tomando un Ct ≤35 como el punto de corte para muestras positivas. El análisis BLASTn de las secuencias obtenidas mostró un porcentaje de identidad del 98% con secuencias 18S del ARN ribosomal de Strongyloides stercoralis reportadas en la NCBI. El límite inferior de detección de la qPCR fue 0,9 ng/µL. No se evidenció reacción cruzada con Ascaris lumbricoides, Trichuris trichiura, Uncinarias, Hymenolepis nana, Entamoeba histolytica/Entamoeba dispar, Entamoeba hartmanni, Giardia intestinalis e Iodamoeba bütschlii. No se detectaron inhibidores en las muestras de materia fecal. Conclusiones: la sensibilidad y la especificidad analítica de la qPCR comparado con el examen directo de heces son del 100%; sin embargo, aún no es posible interpretar su utilidad clínica.
