Naturally acquired visceral leishmaniosis in a captive white-naped mangabey (Cercocebus lunulatus) in Spain.

ABSTRACT: Leishmania infantum infection has recently been identified in non-human primates in Spain, including clinically affected individuals from critically endangered species such as the Bornean orangutan (Pongo pygmaeus pygmaeus). Despite these emerging cases, clinicopathological data on leishmaniosis in captive wildlife remain limited. Here, we report the first confirmed case of clinical visceral leishmaniosis in a zoo-captive white-naped mangabey (Cercocebus lunulatus) in Spain. The affected animal presented with progressive weight loss, generalized lymphadenopathy, polyclonal gammopathy, and cytological evidence of pyogranulomatous lymphadenitis containing intralesional protozoal amastigotes consistent with Leishmania spp. The animal eventually died, and a detailed necropsy was performed.
