Abstract:
A cross sectional study was conducted in Alklakla area near the White
Nile from January to April 2011. The study aimed to determine the
prevalence of Schistosoma haematobium among school children and snail
– parasite compatibility. The study included 500urine sample collected
randomly from targeted children (265 male and 235 female). The
population was classified according to age group into two groups: less
than 12 and 12-16 years. Also, the educational level of parents was
classified into three levels :( low, medium and high) which corresponds to
primary, secondary and graduated education levels respectively.
The urine samples were examined for S.haematobium eggs by using
sedimentation technique. The overall prevalence of urinary
schistosomiasis was 0.6% (3 positive cases). All positive cases were
males who showed direct contact with water and this showed a significant
association between gender and contact with water to the rate of
infection.
In this study, 32 Bulinus snail were collected randomly from shores of the
White Nile by scoping method and examined for shedding of cercaria. All
the examined snails showed no cercarial shedding.
The study concluded that the absence of infection in the studied snails
(Bulinus) was the reason for the infection rate of S.haematobium in the
study area.
