Parasitic infections, caused by intestinal helminths and protozoan parasites, are among the most prevalent infections in developing countries, while in developed countries, gastrointestinal infections are caused more commonly by protozoan parasites compared to helminths. A laboratory analysis of stool samples was done for detection of intestinal parasites in the Microbiology laboratory of a tertiary care hospital for a period of 6 months (February 2017 to July 2017). Stool samples were examined by different methods like direct smears (Saline and Lugol’s iodine) and concentration techniques. Formalin – ether sedimentation method and Zinc-sulphate floatation method and modified Ziehl Neelsen staining method. In our study a total of 231 stool samples were analysed and prevalence of intestinal parasitic infection was found to be 13.41% (31/231). There were five different parasites encountered. The most common parasite identified was Giardia lamblia (52%), followed by Entamoeba histolytica (19.35%), Hookworm (16.12%), Strongyloides stercoralis (6.45%) and Cryptosporidium parvum (6.45%).Use of concentration techniques definitely increased the detection rate when compared to conventional saline and iodine mount examination.

Keywords: Entamoeba histolytica, Giardia lamblia, Strongyloides stercoralis, Concentration techniques
