Evaluation of Efficiency Formal Gasoline Concentration Technique in Detection of Intestinal Infections in Al-Rajhe Hospital in Dar Al-Salam Area, Ombada Locality, Khartoum State- Sudan

Abstract

This cross-sectional study was conducted in Al-Rajhe hospital in Dar Al-Salam area, Ombada locality, Khartoum State- Sudan to evaluate formal gasoline concentration technique in detection of intestinal parasitic infections during the period from October 2018 to October 2019. The study was conducted on 272 patients, 109 (40.1%) were males and 163 (59.9%) were females. Fecal samples were taken from all patients included in the study, in addition , the epidemiological and parasitological data were obtained and recorded. All samples were examined to detect intestinal parasite species by using wet preparation, floatation technique, formal ether concentration technique and formal gasoline concentration technique. The study showed that the prevalence rate of intestinal parasites was (45.5%) and intestinal protozoa were more prevalent (41.5%) than intestinal helminthes (4.0%). The prevalence rate of intestinal parasitic infections by using wet preparation, formal ether concentration technique, formal gasoline concentration technique and zinc sulphate floatation technique were (34.2%), (45.5%), (42.6%) and (28.3%) respectively (p. value=0.000). The highest prevalence rate (18.0%) of intestinal parasites in the study area was reported with Giardia lamblia. The study revealed that the highest prevalence rate (57.3%) was reported among females while males reported (42.7%) prevalence rate. The highest prevalence rate (67.7%) was reported among the ≤ 15 years old. The results showed that the difference in prevalence rates of intestinal parasitic infections according to symptoms was found to be statistically significant (p. value=0.000). The results showed that the difference in prevalence rates of intestinal parasitic infections according to their associated risk factors was found to be statistically significant except with the source of drinking water which was found to be statistically insignificant (p. value=0.991). The study indicated that the prevalence rate of intestinal parasitic infections in the study area was high (45.5%). In addition to, the gasoline proved to be good in concentrating parasite eggs and cysts, as well as in maintaining characteristic morphology.
