Abstract:
The study covers about one hundred and fifty persons between 6- 18
years old in Port Sudan city from May to August, this study aimed to
determine the effects of malaria infection on haemoglobin and white blood
cells deferential count. Blood samples were collected from school pupils to
estimate haemoglobin level, white blood cells differential count and the
presence of malaria parasites. Three groups were compared, infected group,
pre-infected group and non-infected group. The investigation was done by
using Giemsa staining method for malaria and differential counts and Sahli
haemoglobinometer to estimate haemoglobin level.
The study was showed that the mean haemoglobin levels in infected ,
pre-infected
and non-infected groups were 78.3%, 86.1%, 89%
respectively. The differential counts of white blood cells such as neutrophils
were found to be 50%, 56.2%, 58% in infected group, pre-infected group
and non-infected group respectively. Whereas eosinophils were found to be
3%, 1.7%, 1.2% in infected group, pre-infected group and non-infected
group respectively. The basophils were found to be 0.64%, 1.2%, 0.9% in
infected group, pre-infected group and non-infected group respectively. The
lymphocytes were found to be 44%, 38.7%, 37% in infected group, pre-
infected group and non-infected group respectively. finally monocyts were
found to be 3.7%, 2.4%, 3% in infected group, pre-infected group and non-
infected group respectively.
The results showed that the haemoglobin levels decreased in infected
group with highly significant differences (P< 0.01)in contrast the
monocytes, lymphocytes and eosinophils were increased in infected group
with significant differences (P< 0.05, P< 0.05, P< 0.05).
The collected immature water stages of mosquitoes from different sites in
different units, were identified as culexs’ pupae and larvae.
