The paper presents a comparison of the microscopic structure and morphometric traits of gustatory and mechanical lingual papillae in newborn and adult frugivorous Egyptian fruit bats (Rousettus aegyptiacus). All of the four types of lingual papillae found in adult animals were observed on the tongue surface in the newborn Egyptian fruit bats. After the birth, the gustatory papillae (fungiform and vallate papillae) were especially well-developed, as their structural characteristics, such as morphology of the epithelium and presence of the taste buds, indicate that they have reached almost complete functional traits. Mechanical papillae, particularly filiform papillae, in newborns are still fetal in character. Keratinization processes in the epithelium of these papillae are not advanced and specific structures, such as elongated processes, are missing. The morphometric analysis of the size of papillae and thickness of the mucosal epithelium showed that a complete development of keratinized structures in Egyptian fruit bats occurs at later stages of postnatal development.
本文对新生和成年食果埃及果蝠（埃及果蝠）味觉和机械性舌乳头的微观结构及形态特征进行了比较。在成年动物中发现的所有四种舌乳头类型都在新生埃及果蝠的舌表面观察到。出生后，味觉乳头（菌状乳头和轮廓乳头）发育特别良好，因为它们的结构特征，如上皮形态和味蕾的存在，表明它们已达到几乎完全的功能特征。新生动物的机械性乳头，特别是丝状乳头，仍具有胎儿特征。这些乳头上皮中的角化过程不发达，缺少诸如细长突起等特定结构。对乳头大小和粘膜上皮厚度的形态计量分析表明，埃及果蝠角化结构的完全发育发生在出生后发育的后期阶段。
