The slow loris (Nycticebus) is a prosimian that is popular among exotic pet lovers. In Japan, many slow lorises have been imported illegally. Prosimians that have been confiscated in raids are protected in Japanese zoos, and the number of such animals has increased. In most cases, the country of origin remains unknown and even the species can be difficult to identify from the animal's physical appearance alone. We have attempted to resolve this problem by using DNA analysis. DNA samples of five species, consisting of the Pygmy slow loris (Nycticebus pygmaeus), Bengal slow loris (Nycticebus bengalensis), Sunda slow loris (Nycticebus coucang), Javan slow loris (Nycticebus javanicus), and Bornean slow loris (Nycticebus menagensis), were extracted, amplified, and the nucleotide sequences of mitochondrial 12S rRNA, 16S rRNA, and the cytochrome oxidase subunit 1(COI) regions were compared. Differences of nucleic acid sequences of representative individuals were demonstrated.

The monkey showed apparent swelling of the facial region, and physical examinations revealed gingival swelling and osteolysis of both the mandible and maxillary region, Incisor regions of the maxillary and mandibular bones were replaced by neoplastic tissue, and a white nodule was found on the right cervical lymph node, Histopathelogical exarninations revealed that the neoplasrn was composed of multiple variably-sized islands of malignant neoplastic squamous epithelia] cells with metastasis to the right cervical lymph node, This is the first report of oral squamous cell carcinoma in a leaf-monkey reared at a Japanese zoo.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
