Abstract:
In order to identify the prevalence rate of intestinal parasitic infections among primary school children, this cross-sectional study conducted in Almahana (Jafawa) village in Kordofan State. The study involved one hundred stool samples collected from children aged less than 12 years. By using direct wet preparation (DWP), triple direct wet preparation (3DWP), Zinc Sulphate floatation technique (ZnSO4 FT) and formal ether concentration technique (FECT) to process the samples. The results showed that (45%) of children were harboring different gastrointestinal parasites. The study revealed that protozoa was seen in (64.4%), while helminthes and co-infection of protozoa and helminthes were seen in (24.4%) and (11.1%) respectively. Out of 45 positive cases, single parasite infections were found among 35 children (77.8%), were as (22.2%) children were found to be infected with multiple parasitic infections. When using different techniques for all samples of study population, FECT proved to detect higher rates of different parasites encountered. The highest rate (48.9%) was reported for G.lamblia, followed by Hymenolepis nana (22.2%), Entamoeba histolytica (4.4 %) and Entrobius vermicularis (2.2%). The results also showed that using of floatation technique could not recover a single case of Entamoeba histolytica. Although there was differences in detection of different parasites by different techniques, unfortunately these differences in rates were found to be statistically in significant with (p. value= 0.848). Gastrointestinal parasites were highly prevalent among primary school children (45%) in Kordofan State. FECT proved to have high sensitivity rate of detection of different gastrointestinal parasites.
