Abstract:
This study was conducted in radiation-isotope centre (RICK) in Khartoum
state, where stool samples were taken from 50 patients presented with
leukemia and cancer other than leukemia.
Stool samples were examined for the presence of intestinal coccidian parasites
by direct wet preparation, formal ether concentration technique and modified
3
ZN staining technique. The results showed that 5 (10%) of the presented
patients have intestinal coccidian parasites.
The study demonstrated that the prevalence rate of C. parvum (8%) was found
higher than the rate of I. belli (2%) in immunocompromised patients.
The study revealed that the prevalence rate of C. parvum among males (8%)
and females (8%) was equal, and the prevalence rate of I. belli among males
patients (4%) was higher than female patients (0%).
The highest prevalence rate of C. parvum (20%) and I. belli (10%) was
reported among the 16-25 years age group, while the lowest (0.0%) was
reported among the below 15 and above 45 years age groups for C. parvum
and the rest of the groups for I. belli.
The result showed that the prevalence rates of C. parvum were 12 % and 0 %
among the patients of cancer other than leukemia and patients of leukemia
respectively. However, the prevalence rates of I. belli were 6 % and 0 %
among the leukemia, and cancer other than leukemia patients respectively.
The study revealed that the sensitivity and specificity rates of the formal ether
concentration technique were 60% and 100% respectively, while the
sensitivity and specificity rates for the modified ZN staining technique were
100% and 95.7% respectively.
