英文摘要

Peccaries are characterized by a prominent skin gland, known as scent gland, which is located in the middle of the rump. These animals are able to survive in a great variety of habitats, from humid tropical forests to semi-arid areas. They are omnivorous animals, and their diet includes fibrous material, vegetables, fruits, small vertebrates and insects. Collared peccary hard palate and soft palate tonsils were studied, macroscopic morphometric data were collected and tissue samples were paraffin-embedded. Sections were stained with HE, Gomori’s trichrome and von Kossa; the first two were used to study general organization and the latter to detect calcium deposits. The hard palate showed one incisive papilla followed by several rugae united by a distinct raphe. The hard palate is lined by a keratinised squamous epithelium resting on a dense connective, whereas in the soft palate, the epithelium is parakeratinised and showed lymphocyte infiltration. The palate showed several pacinian corpuscles in the propria-submucosa. Two ovoid-shaped tonsils were found in the soft palate, and several crypts were observed on its surface. The epithelium was highly infiltrated by lymphocytes, and within the crypts, tonsilloliths were frequently observed. The study showed that the general organization of collared peccary palate is similar to other species, but in its oropharynx, only the soft palate tonsil was present and the pacinian corpuscles formed small aggregates.
