Intestinal parasites in Dakahlia Governorate with different techniques in diagnosing protozoa

ABSTRACT

A total of 318 patients attending Mansoura University Hos-pitals' Clinics, were subjected to stool examination by direct wet smear, formol ether concentration, original formol-tween con-centration, modified formol-tween concentration, modified sheather's sugar floatation, potassium hydroxide concentration and Gomori's Tirchrome stain, and modified Kinyoun's acid-fast-sta-in and Ryan's Tirchrome blue stain for Microsporidia. The inte-stinal helminthes in a descending order of abundance were S. mansoni [5.3%], Fasciola sp. [4.8%], H heterophyes [4.2%], Hymenolepis nana [3.9%], trichostrongylus sp. [2.6%], A. lum-bricoides [1.8%], strongyloides stercoralis [1.5%], H. diminuta [1.4%], Taenia saginata [1.1%], E. vermicularis [by smear; 1.1%], T. trichura [0.7%] and lastly A. duodenale [0.1%]. The inte-stinal protozoa in a descending order of abundance were Blasto-cystis hominis [22.4%], Giaradia lamblia [19.6], Entamoeba histolytical E. dispar [19%], Iodamoeba butschlii [16%], Crypto-sporidium parvum [14.3%], E. coli [9.7%], isospora hominis [7.7%], Endolimax nana [6.9%], E. hartmani [5.9%], Dien-tamoeba fragilis [5.1], chilomastix mesnili [5.1%], tricho monas hominis [4.2%], Cyclospora cayetanensis [4.2%], Mic-rosporidia spores [3.2%], Enteromonas hominis [1.9%] and Em-badomonas intestinalis [1.3%]. The results were discussed.
