An Epidemiological Study of Protozoan Parasites in the Human Body
Paripex Indian Journal Of Research, 2020
Amoebiasis, caused by Entamoeba histolytica, has a worldwide distribution and is of public health significance in many developing countries. It has a fecal-oral transmission cycle and is most prevalent in developing countries in regions where substandard sanitary conditions exist due to poverty. Saharsa town is the headquarter of Koshi Division of Bihar lying in koshi belt witnesses higher percentage of incidence of intestinal parasites. The town has no drinking water supply and people mostly use drinking water from low-deep hand pump. The perennial water logging in mohallas, insanitary disposal of human excreta and use of drinking water from low-deep hand pumps prevailing in the town favours the infestation of intestinal parasites.
Prevalence of Intestinal Protozoan among Students Visiting Wollega University Students' Clinic
2013
Protozoan parasites Giardia lamblia, Entamoeba histolytica/dispar, and Cryptosporidium parvum are ubiquitous that affect humans, domestic animals and wildlife throughout the world and have been highlighted as significant waterborne parasitic pathogens. The present study was conducted to on the prevalence of intestinal protozoan among students visiting Wollega University clinic from March16 to April 31, 2013 to identify the most prevalent intestinal protozoan, to see the risk factor and to suggest control mechanism. Single stool specimens were collected from a total of 350 students of different age range and processed for Giardia, amoeba, C. parvum and other intestinal parasites were detected using formalin-ether concentration and direct wet mount methods. Out of 350 students examined, an overall prevalence of 19.9% intestinal protozoan infection was found. Of this 111(31.6%), 44 (12.5%), and 8 (2.3%) were infected with Entamoeba histolytica/dispar, Giardia lamblia, and Cryptosporidi...

Background: In the world there are plenty of parasites such as intestinal parasites and freshwater parasites. Protozoa is one of the most well-known intestinal parasites; which also lives in humans’ intestine. Those which survive in the guts of humans can cause severe and serious disease. These protozoa are like amoeba, flagellates, ciliates and coccidians. Objective: This article was aimed to evaluate the diseases caused by the common intestinal protozoa of humans and their symptoms, prevention & treatment. Methods:Survey of different literatures on the topic. Results: Toxoplasmosis, leishmaniasis and dysentery were the most common diseases caused by intestinal parasites. Conclusion: Concerned organizations like WHO and UNFDP have to emphasize in preventive and curative aspects of the intestinal parasites.

This study aimed to determine the frequency of infection by intestinal protozoa diagnosed in patients from a clinical analysis laboratory in Maceió, Alagoas, Brazil. This was a retrospective descriptive study, using a database of stool examination results from July to December 2015. The study population consisted of males and females of all ages, from the greater area of Alagoas. Data on epidemiological variables such as age and gender were obtained using a collection instrument. Protozoan species were identified from stool examinations. Results on the prevalence of intestinal parasites are described as simple and relative frequencies. We examined a total of 1277 stool samples, of which 12.69% were positive for one or more protozoa. 43.83% were from men and 56.17% were from women. Endolimax nana was the most prevalent (59.22%) protozoan species followed by Entamoeba coli (23.45%). Although non-pathogenic, they indicate fecal contamination of drinking water. The highest number (23.46...
EPIDEMIOLOGY AND PUBLIC HEALTH IMPORTANCE OF FOODBORNE PROTOZOAN DISEASES
Food-borne illnesses comprise a broad spectrum of diseases and are responsible for substantial morbidity and mortality worldwide. It is result from consumption of food containing pathogens such as bacteria, viruses, parasites or the food contaminated by poisonous chemicals or bio-toxins. Many parasitic infections are associated with poor sanitation, contaminated food and water, overcrowding, under nutrition, and other poverty-related factors. Current estimates showed that at least more than one-quarter of the world's population is chronically infected with intestinal parasites and that most of these infected people live in developing countries. Foodborne parasitic zoonoses include both helminthic and protozoan infections. Foodborne and waterborne protozoan diseases caused by Cryptosporidium parvum, Cyclospora caytanesis, Giardia lamblia, Entamoeba histolytica, Balantium coli, Sarcocystis spp. and Toxoplasma gondii affect many millions of people worldwide. Food borne protozoan infections have been recently identified as an important public health problem having considerable economic impact in terms of morbidity, loss of productivity and health care costs. Control of such foodborne protozoan infections is being improved by mass chemotherapy approaches using donated drugs. Education of consumers, food handlers, and food producers particularly regarding basic hygiene, sufficient cooking, and avoiding cross-contamination have all had an impact on food borne transmission of pathogens and remain imperative to food safety. It is important to strengthen veterinary services to enhance efforts to control infections in livestock.
