Mucocutaneous candidiasis in a mandrill (Mandrillus sphinx).

An adult male mandrill (Mandrillus sphinx) suffered from chronic ulceration of the facial and gluteal skin and the oral and nasal mucosa. The ulcers were resistant to therapy and led to deterioration in the general condition of the animal. Microscopical examination revealed a severe, chronic, multifocal, granulomatous and eosinophilic dermatitis and panniculitis.

Comparative investigations on digestion in grazing (Ceratotherium simum) and browsing (Diceros bicornis) rhinoceroses.

Rhinoceroses represent the largest extant herbivores with extensive dietary specialization for plant groups like browse (black rhino Diceros bicornis) or grass (white rhino Ceratotherium simum). However, it is not clear to what extent such diet selection patterns are reflected in adaptations of digestive physiology of the respective feeding types. In this study, feeding trials with four black and five white rhinos were conducted in four zoos.

Lethal pneumonia in a captive juvenile chimpanzee (Pan troglodytes) due to human-transmitted human respiratory syncytial virus (HRSV) and infection with Streptococcus pneumoniae.

Background: During an outbreak of respiratory disease in captive chimpanzees (Pan troglodytes), gorillas (Gorilla gorilla), Bornean orangutans (Pongo pygmaeus), and red-capped mangabeys (Cercocebus torquatus) also staff members showed non-specific upper respiratory signs. One infant female chimpanzee with severe respiratory symptoms died despite immediate medical treatment and was submitted for necropsy.

Methods: Routine post mortem, histological and bacteriological examinations were conducted.

Artificial insemination in the anoestrous and the postpartum white rhinoceros using GnRH analogue to induce ovulation.

The objective of this study was to develop AI and to achieve first time pregnancy in a nulliparous rhinoceros. For this, one 24-year-old irregular cycling female white rhinoceros was selected, which had never been mated. The endocrine function was monitored by faecal and serum pregnane analysis.

The effect of long non-reproductive periods on the genital health in captive female white rhinoceroses (Ceratotherium simum simum, C.s. cottoni).

White rhinoceroses suffer from a low reproductive rate in captivity. Intensive efforts to propagate specifically the northern white rhinoceros have been very limited. The dismal outlook for this subspecies in the wild makes successful ex situ breeding programs paramount.
