Hematological and Immunological Mechanisms of Adaptation to Hibernation in Common Indian Toad Duttaphrynus melanostictus

Suman Pratihar, Jayanta Kumar Kundu


Some hematological parameters of the hibernating and non hibernating toads Duttaphrynus melanostictus have been investigated. The immunoglobulin IgM amount, total red blood cell and neutrophil counts were significantly less (p < 0.05) in the hibernating toads as compared to the non hibernating ones. On the contrary, total white blood cell, eosinophil and lymphocyte counts were significantly more (p < 0.05) in hibernating individuals. No significant difference in the monocyte amount was observed. Hematological and immunological mechanisms of adaptation to hibernation in amphibians are discussed.
