Abstract

To analyse the involvement of immune cells in the pathogenesis of diseases of various aetiologies, and to inform therapeutic and preventive interventions, it is essential to understand the normal morphology of the immune system organs and tissues. This study presented the findings of a morphological investigation of the secondary (peripheral) immune system organs in the Asian wild boar subspecies (Sus scrofa nigripes) inhabiting the forest-steppe region of the Moskva District, Chüy Region, Kyrgyz Republic. This research aimed to identify the general morphological and functional features of the lymphoid structures of the spleen, mesenteric lymph nodes, and haemolymph nodes in healthy animals. Study materials were collected from three sexually mature wild boars. Anatomical and histological methods were employed to achieve the study aim. Anatomical methods were used to determine the syntopy, shape, colour, and consistency of these organs. Histological studies were carried out using standard techniques: haematoxylin and eosin staining was employed to examine the general structural organisation of the organs, while Van Gieson’s method was used to differentiate muscular and connective tissue elements. Light microscopy was used to analyse the stromal and parenchymal structure, cellular composition, and morphofunctional state of lymphoid formations. The study established the morphofunctional condition and morphological characteristics of the spleen, lymph nodes, and haemolymph nodes in sexually mature Asian wild boar subspecies. The findings represented the morphological norm for the secondary immune system organs of this subspecies. These results may serve as a reference framework for future experimental and applied research in the morphology and immunology of organs and tissues in wild boars, both under normal conditions and in pathological states. The data may also be of practical use to veterinary specialists and biologists engaged in functional, ecological, and comparative morphology of organs in domestic and wild animals
