Comparative differential leucocyte count and morphometrical analyses of black rats Rattus rattus (Linnaeus, 1758) and white rats Rattus norvegicus (Berkenhout, 1769)
Journal Title: African Journal of Biological Sciences - Year 2019, Vol 1, Issue 1
Abstract
This paper aims at a systematic approach to morphologically characterize of five types of white blood cells (WBC), and its nuclei from light microscopic image of blood samples. Hence, cellular and nuclei based geometric features are computed and analyzed statistically with t-test to show their discriminating potentiality among the species. In morphometry study, the length and breadth along with nucleus of leukocytes are compared between and within the species using oneway Analysis of Variance (ANOVA) followed by Tukey’s pairwise comparison tests. In this study, the estimated values of Rattus rattus and Rattus norvegicus with respect to sex were compared. A total of 20 black and white rats (05 each from males and females) were collected. Blood samples were then collected from the caudal vein of anaesthetized rats. In differential leucocyte count, the parameters namely, lymphocyte, monocyte, neutrophil (p < 0.001) and eosinophil and basophil (p < 0.05) reveal significant difference. In morphometrical study, the cell length, breadth along with nucleus of lymphocyte, monocyte, neutrophil (p < 0.01) and eosinophil, basophil (p < 0.05) deviates significantly between and within the species.
