Abstract:The present study was carried out to elucidate Comparative histomorphology and histochemical study of superficial lymph nodes in Deccani sheep (
Ovis aries) and Bidri goat (
Capra hircus). Superficial lymph nodes namely prescapular, prefemoral, parotid, mandibular and inguinal lymph nodes of both species consisted of capsule which covered whole parenchyma except at hilus.
Weak PAS positive results showed presence of less amount of mucopolysaccharides in capsule, trabeculae and cytoplasm of lymphocytes and connective tissue surrounding lymphocytes. Alcian blue reaction at pH 2.5 confirms the presence of sulfomucin and sialomucins in capsule, trabeculae and connective tissue surrounding lymphocytes in both species. Parenchyma of prescapular and inguinal lymph nodes showed the presence of lipids when stained with Oil red O stain.
