title: Intestinal parasitic infections among patients attending Nepal Medical College Teaching Hospital, Kathmandu, Nepal.
abstract: This study was conducted to find out the prevalence of intestinal parasitic infection among patients attending Nepal Medical College Teaching Hospital, Kathmandu from July 2011 to February 2012. A total of 312 stool samples collected in a clean, dry screw capped plastic container were examined using the formal-ether concentration and sucrose-flotation techniques. Overall parasite positivity rate was 30.1% with significant difference between males (34.2%) and Female (26.3%) (p < 0.05). Out of total positive, 90.4% had single parasitism whereas 9.6% had multiple parasitism. Children aged < or = 5 years were found to be highly infected (35.8%), followed by 6-15 years (32.1%) and > 15 years old (26.9%). Rate of infection was significantly higher among patients from inside Kathmandu Valley (31.1%) than outside valley (17.4%) (p < 0.05). E. histolytica (38.5%) and Hookworm (10.6%) were the commonest protozoa and helminthes respectively. Other parasites detected were G. lamblia (26.0%), E. coli (1.0%), T. trichiura (7.7%), A. lumbricoides (6.7%), H. nana (5.8%) and Taenia species (3.8%). Out of total parasites detected, 65.4% were protozoa and 34.6% were helminthes. Positive rate was higher in Dalit (37.5%) and Aadibasi-Janjati (34.3%) than Brahman-Chhetri (22.6%) (p < 0.05).
