Hand-raising a spectral tarsier (Tarsius tarsier) at the Ueno Zoological Gardens.

On February 10, 2008, a newborn male spectral tarsier (Tarsius tarsier) was found on the floor of the indoor exhibit room in the Small Mammal House of the Ueno Zoological Gardens. The dam showed no signs of providing maternal care and therefore we decided to hand-raise the infant. Its birth weight was 18.

A survey of amoebic infections and differentiation of an Entamoeba histolytica-like variant (JSK2004) in nonhuman primates by a multiplex polymerase chain reaction.

A pathogenic Entamoeba histolytica-like variant (JSK2004 strain) with genetic variations and a novel isoenzyme pattern isolated from a De Brazza's guenon in a Tokyo zoo in Japan has previously been documented. In this study, a multiplex polymerase chain reaction (PCR) assay that could distinguish the JSK2004-type E. histolytica-like variant (JSK04-Eh-V) from E.

A trial of intrauterine insemination using a fiberscope in the giant panda (Ailuropoda melanoleuca).

An intrauterine insemination technique using a fiberscope was investigated in the giant panda. A septal wall was present about 5 cm from the vulva, the external urethral orifice was present in the ventral region, and the entrance (pseudocervix) to the vagina was present in the dorsal region. The uterovaginal region protruded in the dorsal region about 15 cm from the pseudocervix.
