Item Epidemiology of Intestinal Parasites in A Rai Community of Nuwakot District(Department of Microbiology, 2013) Puri, RajuIntestinal parasitosis is highly endemic in developing countries and usually implicates the children and pregnant women along with the people residing in filthy environment, urban slums and crowded areas. The dissertation was conducted from March to October 2012 to study the prevalence and distribution of intestinal parasites in a Rai community of Nuwakot district. Soil, vegetables, water and fecal samples were collected, processed and studied to correlate the distribution pattern of the intestinal parasites. Sucrose floatation and saturated brine floatation techniques followed by direct smear were used for the processing of soil and vegetable samples respectively. The soil samples contamination rate was found to be 26.5% with the dominance of Ascaris lumbricoides followed by hookworm (Ancylostoma duodenale and Necator americanus). Soil samples from toilet vicinity and vegetable fields were the most contaminated soils. Vegetable samples were collected directly from the field. Of the 59 samples tested, 39% were found to be contaminated with the intestinal parasites. Helminthic preponderance was observed with the Ascaris lumbricoides and hookworm topping the list. Giardia lamblia and Entamoeba coli were also isolated from the vegetables. Leafy vegetables were the most contaminated vegetables which were followed by root vegetable. Water sample was processed following elution with saline after filtration. Only water samples from irrigation channel were found to be contaminated and the parasites detected were Giardia lamblia, Ascaris lumbricoides and Trichuris trichiura. The intestinal parasitosis was highly prevalent in the community with the prevalence rate of 56.7%. Helminthic parasites superseded the protozoans. Protozoans were detected only from polyparasitic infection. Monoparasitism (70%) was common to polyparasitism (30%). Trichuris trichiura was found predominant among the community children. It was implicated in almost twothird of the cases. Unavailability of toilet facility in home imposed statistically significant (P<0.05) risk of parasitic infection. Male children were the major victim of the intestinal parasites in comparison to female children and the difference was statistically significant (P<0.05). A statistically significant relation was detected between the intestinal parasitic prevalence and fathers’ involvement in agriculture (P<0.05). The children of age group 4-8 years were most vulnerable to parasitic infection which was closely followed by age group 8-12 years. Besides, irregular footwear using habit, absence of antihelminthic drug uptake within last six months, poor hygiene, joint and family with more than five members were found to be favorable for the intestinal parasites. The contaminated environment and unhygienic habits were the major contributing factors to facilitate the distribution and prevalence of intestinal parasites in the community.

The researcher collected data from primary and secondary sources. For primary sources the researcher selected twenty literary figures from Chitwan and Nawalparasi districts by using purposive sampling. Moreover, the researcher collected information from the author of the very novel 'Sukarat Ka Paila'. The researcher employed the diary, unstructured interview schedule and questionnaire as the research tools. This research study concludes with the findings that English code mixing in the Nepali language is common phenomenon. It is the cause of different factors like author's acquaintance in the English language, due to linguistic imperialism, due to advancement and rapid expansion of the English language, etc. among the mixed English expressions, word level expressions were high. Within word level also nouns were more in comparison to others. Thus, code-mixing is natural and common phenomena that every Nepali native speaker believes and accepts. This research work entails four chapters. The first chapter deals with introduction which, in turn, consists of general background, review of related literature, objectives and significance of the study. The second chapter deals with methodology.It incorporates sources of data both primary and secondary, tools for data collection, data collection procedure and limitations of the study. The third chapter consists of analysis and interpretation of the data to identify the reasons and perceived attitudes of the literary figures and author towards English code-mixing in Nepali expressions. The collected data were analyzed and interpreted separately by giving main headings and sub-headings. Such as interpretation of information collected from three tools. Finally, it also provides some recommendations on the basis of findings. The final section of the study incorporates the references and appendices.
