Abstract
In this study, white blood cell counts and morphological characteristics of peripheral blood cells were determined. Bat specimens were collected from Koyunbaba Cave in Kırklareli Prov. in November 2007. The highest and lowest lymphocyte counts were determined in M. myotis (70.4±12.09) and R. ferrumequinum (53.3±14.83), respectively. When comparing the neutrophil counts of the species, it was seen that the highest value belongs to R. hipposideros (37.75±18.03) and the lowest one belongs to M. capaccinii (17.88±12.50). The highest percantage of monocytes was seen in R. ferrumequinum (12.55±5.77) where as R. hipposideros (7.75±3.89) has the lowest counts. The white blood corpuscle populations have also been compared with other bat studies.
