Abstract : Intestinal parasitic infections continue to be an important cause of morbidity and mortality in the developing countries including India. A study was carried out on intestinal protozoan parasites in Patna district during the year 2015 to 2016 with the purpose of achieving a better understanding of the incidence of the disease. A total of 588 stool samples were collected randomly from the inhabitants of selected areas and examined by simple saline preparation technique. In addition stained preparation by Lugol’s iodine solution was also used for the identification of nuclear character of the cysts. Chi-Square test (2 – test) was used to compare relative frequencies between sex specific incidence. 34% of the population (198/588) was found to be harbored with parasites. The incidence of infections for various protozoan parasites was as follows Entamoeba histolytica (19.5%) Entamoeba coli (7.6%) and Giardia lamblia (3.4%). About 3% of the samples contained multiple infections. The study revealed that the prevalence of intestinal protozoan parasites in Patna district is still so high and required special control measures.
