Abstract

BACKGROUND: The dromedary spleen plays a crucial role in the immune system and maintaining homeostasis. However, there is limited research on the developmental changes that occur in the spleen during the first few years of a dromedary's life
OBJECTIVES: The objective of this study was to comprehensively investigate the developmental changes that transpire in the dromedary spleen during the crucial first three years of life. This was achieved through a multi-faceted approach, involving both macroscopic examination, which entailed measuring the absolute and relative mass of the spleen, as well as morphometric analysis. Additionally, histological and histomorphometric analysis were employed to study the cellular composition of the spleen at different ages.
METHODS: Five groups of dromedaries were examined in Southeastern Algeria. The spleens were analyzed using both gross anatomy and histological examination. The cellular composition of the spleen was studied on histological slides of spleens of different ages, which were stained with hematoxylin and eosin.
RESULTS: The results showed that the size, weight, and volume of the spleen significantly increased as the animals aged. The splenic mass of the animal of the first group showed an average absolute mass of 251±14.19 g, whereas in the fourth group they showed an average mass of 318±23.91 g, while the length, the width and the thickness showed average values of 43.78±1.95 cm, 19.44±1.52 cm, and 1.88±0.16 cm respectively at the age of eight months, while they showed average values of 49.6±1.86 cm, 24.32±1.69 cm and 3.18±0.34 cm respectively at the age of three years. The cellular composition of the spleen changed over time, with a higher percentage of lymphoid tissue at eight months, more red pulp at one year, and a higher percentage of white pulp at two years. By three years, the spleen had a mature mix of red and white pulp and its immune function was fully developed.
CONCLUSION: This study provides new insights into the development and maturation of the dromedary spleen. The findings have important implications for understanding the health and well-being of these animals, and could potentially contribute to the development of better strategies for the management and care of dromedaries
