Abstract:
This survey was conducted in different hospitals in
Omdurman city. The study involved three hundred stool
samples collected from 200 patients with irritable bowel
syndrome (IBS) and another 100 as control, during the
period between May and December (2011). The result
showed that 112(56%) of irritable bowel syndrome
patients were harboring gastrointestinal parasites and
20% of the control as well.
The study revealed that Giardia lambilia was seen in
28.5% of the irritable bowel syndrome cases, followed by
Entamoeba histolytica in 9.2% of cases, Hymenolepis
nana (7.0%), Taenia spp (4%) and Entamoeba coli and
Ascaris lumbricoides (3.5% each).
Lower rates were reported among the control group
where G. lamblia was seen in 10% of the cases, E. coli in
5%, E. histolytica in 1%, H. nana in 2% and Taenia spp in
2% of the cases.
The result demonstrated that the prevalence rate of
gastrointestinal parasites among males and females was
almost the same (55% and 57% respectively).
On the other hand, the prevalence of gastrointestinal
parasites among males and females in the control group
was found to be 22% and 18% respectively.
The highest prevalence rates (61.5% and 60%) were
reported among the 21-30 and 31-40 years age grouprespectively, while the lowest rate (22.2%) was reported
among the 10-20 years age group for the IBS patients.
For the control group, the highest prevalence rate
(23.3%) was reported among the 21-30 years age group,
while the lowest prevalence rate (13.3%) was reported
among the over 40 years age group. All individuals in the
10-20 years age group were refractory to infection.
It was revealed that infection with G. lamblia was the
highest (28.5%) in the IBS patients followed by E.
histolytica in 9.2% of the cases. In the control group, an
infection rate of 10% was reported for G. lamblia.
