ABSTRACT
The studies on haematologic changes in humans or animals as a result of mosquito bites are few. This study was undertaken to examines changes in the blood picture of mice[Mus muscu-lus] exposed to culexpipiens biting Mice exposed to mosquito bites either once twice [with7days between the two bites showed insignificantly higher [P>0.05] counts of the total blood cell, platelets and hemoglobin content than normal mice with the highest level [11%] was in WBCs following the second bite mosquito biting exerts its effects largely upon the differential WBCs. Exposure of mice once or twice to mosquito bites resul- ted in increased numbers of the 5 WBC types.compared to control mice cells, the highest [P < 0.01] levels of basophils [7.19-fold, 72.02 cell/ul],eosinophils [3.59-fold, 216.05 cells/ul], monocytes [1.34-fold, 288.08 cells/ul and lymphocytes [1.29-fold, 1833.74 cells/ul] were after the second bite. Segmented neutrophils significantly [p < 0.01] decreased by 2% and 5%of the normal mice count following first and second bite, respectively
