Abstract

The study was carried out to determine the prevalence of Entamoeba histolytica and Giardia lamblia among primary school pupils in four communities of Bosso Local Government Area in Niger State, Nigeria. Stool samples from 250 pupils were collected and examined for Entamoeba histolytica and Giardia lamblia using formol ether concentration technique. Out of the 250 samples analyzed, 115 (46%) for either Entamoeba histolytica or Giardia lamblia or both. Ninety (36.0%) subjects were positive for Giardia lamblia while 46 (18.4%) subjects had Entamoeba histolytica. Single species infection was seen in 78 (67.8%) of the infected pupils whereas 47 (40.9%) were infected with both parasites. The age group (9-10) years had the highest rates of infection of 14 (21.5%) and 37 (56.9%) for G. Lamblia and E. histolytica respectively. Males had the highest rate of infection (53.5%) compared to the females with (46.3%). Poverty, ignorance and poor environmental sanitation were factors found to be associated with the high prevalence rates recorded.
