ABSTRACT
Intestinal parasitic infections are highly prevalent among the general population in developing countries and these infections can lead to a number of adverse effects. This study was done to determine the predominant intestinal parasitic infestations with haematological correlation among all age groups of patients attending tertiary care hospital. A total of 238 stool & blood samples were collected from the patients for examination and haematological analysis. Out of 238 stool samples, 52 (21.8%) showed presence of ova/cysts of Protozoa or helminths. Helminthic eggs were 14.3% and Protozoal cysts or trophozoites were found in 7.5% of them screened for the parasites. Among these Ancylostoma duodenale was found predominant with 10.5% followed by Entamoeba histolytica with 5.5% of total patients. In our study parasitic infestations was predominant in 41-60 yrs. The study showed a relationship between parasitic infestation and Hb, Platelet count, PCV and MCHC which was decreased in protozoal infestations. Their occurrence is quite low compared to other studies which suggests an improved awareness of hygiene. Prevalence of helminths was higher than protozoa in the present study. Hence, it is recommended that appropriate steps be taken at the district level to prevent such infections among pediatric and adult age groups in rural Devanahalli.
