Hematological changes in mice exposed to biting of the bedbug: Cimex lectularius L. (Hemiptera: Cimicidae).
The studies on hematologic changes in humans or animals as a result of bedbug bites are lacking. This study was undertaken to examine changes in the blood picture of mice (Mus musculus) exposed to Cimex lectularius biting. As compared to the check animals, mice exposed to bedbug bites either once or twice within 7 days showed insignificantly higher WBC's (1.6 and 2.8% increase, respectively) and lower HGB content (0.5 and 0.8% decrease, respectively) and significantly higher PLT's (P < 0.01) by 2.2% and 3.0%, respectively. Significantly higher (P < 0.01) RBC's counts in mice bitten once than those of normal animals or those exposed to twice bites (5.3 and 5.9% increase, respectively). Bedbug biting exerts its effects largely upon the differential WBC's. Mice bitten once or twice showed significantly lower number of neutrophils (1.2% & 12.1% decrease, respectively) than those for normal animals. Mice exposed to twice bites showed significantly (P < 0.01) higher numbers of lymphocyte (18.8%), monocyte (13.6%), eosinophil (200.0%) and basophil (500%) than those of normal mice.
