|Abstract: ||Soil-Transmitted helminthes is prevalent in many communities in the Kassena-Nankana district
of the Upper East Region of Ghana. Gia is one community where the prevalence of
soil-transmitted helminthes has been reported in 2007 to be 10% prevalent by the direct wet
mount method. This study determined the current prevalence of soil-transmitted helminthes
among primary school pupils in Gia and Kajelo communities in the Kassena-Nankana district
using direct wet mount and the formol-ether concentration techniques.
Three hundred and ninety-four stool samples were collected from subjects (pupils) between
October 2010 and March 2011 for this study. Each stool sample was processed within two hours
after collection using the direct wet mount and the formol-ether concentration techniques in
accordance with standard protocols.
Formol-ether concentration technique, gave the highest overall prevalence of 9.40% of
helminthes parasites made up of Strongyloides stercoralis (5.08%), Hookworm (3.30%), Ascaris
lumbricoides (1.02%) and Trichuris trichuira (0.00%) in both Gia and Kajelo pupils. The direct
wet mount was found to be 33.3% sensitive.
The Gia primary school had a population of 198 pupils, 6 positives were detected out of the total
number sampled representing 3.54% of the stool samples that were detected by the direct wet
mount method. The formol-ether concentration detected 21 positives of the total number sampled
The Kajelo primary school had a population of 196, 5 positives were detected out of the total
number sampled giving a prevalence of 2.55% with the direct wet mount method. The
formol-ether concentration detected 16 positives out of the total number sampled giving a prevalence of 8.16%.
This study supports the finding that stool samples that are negative for parasites by the direct wet mount method should be re-examined using the formol-ether concentration technique as the
confirmatory test. This approach will improve the detection of helminthes from stool specimens
for accurate diagnosis of soil-transmitted helminthes infections and ultimately improve the quality of life of individuals in these communities.|
