Abstract

A total of 2321 faecal samples were collected from infant children and their parents. Twenty two different localities were selected comprising two day-care centre one nursery one hospital (children ward) nine schools four villages and five residential colonies. This survey was conducted through the year 1993-1997 Information regarding epidemiological factors responsible for parasitic infection were collected through distribution of questionnaire/ Performa among uneducated families. While in villages and hospital /wards personal visits were made. Through observations and interviewing parents, teachers and surveying staff particularly those preparing food and diapering infants and children both in houses schools day care centre and hospitals were made. Personal hygiene feeding behavior, pattern practices believes and customs were noted. Environmental conditions of all these study areas were deeply investigated Fresh faecal samples were collected during the day time daily cleaned sterilized, disposable bottles/containers were provided to each child/infant. All in formations regarding name, age sex, income residence and data and time were provided with these bottles. Routine laboratory procedure took place within 3 hours of collection. Fresh as well as preserved faecal samples were examined for parasitic infections. Methods used for preservation and examination of faecal sample were: Formaline saline preservation, Merthiolate Iodine-Formaline (MIF) preservation technique polyvinyl Alcohol (PVA) method concentration and staining methods fkor slide presparatlions This study was restricted to parasites of protozoan and helminthic origin, with the special interest to assemble reliable information regarding the type and frequency of occurrence of these pathogens and to record epidemiological factors prevailing in this region The most likely cause of diarrhea is infections caused by contamination. This study provide knowledge about etiological significance of epidemiological factors towards parasitic infection in infants and children Analysis of this data and observations revealed some facts regarding epidemiological factors and endemicity of gastrointestinal parasites in middle class population in Quetta. The most common parasite causing diarrhea were: Giardia lamblia Entamoeba histolytica, E. coli Balantidium coli, Ascaris lumbricoides, Hymenolepis nana enterobius vermicularis and some others. A High incidence of amoebiasis, giardiasis hymenolepiasis and ascariasis were recorded during this investigation. Nine species of protozen and four species of helminthes were recorded. Species-wise overall infaction of Entameba coli 57.38% E. Histolytica 23.33% Giardia lambia 20.11$ Balantidium coli 2.18% Blastocystic hominis 1.81% Chilomastix mesnellii 4.76% lodamoeba butschellii 0.79% Endolimax nana 0.41% Ascaris lumbricoides 6.51% Enterobius vermicularis 4.07% Hymenolopis nana 9.08% Trichiuris trichiura 0.08% were recorded
