At necropsy, the right adrenal was replaced by an ovoid mass and the liver had numerous multifocal circumscribed metastases on external and cut surfaces.

PERITONEAL MESOTHELIOMA IN A JAGUAR (PANTHERA ONCA)

Journal of Zoo and Wildlife Medicine, 2013
A 21-yr-old female jaguar (Panthera onca) died in a zoo in Teresina, Piaui, Brazil, following a history of abdominal distension, ascites, anorexia, and dyspnea. At necropsy, a dark red, watery, blood-tinged serous fluid was present in the abdominal cavity. The peritoneum was thick with firm, yellow, villous projections.

Cannibalism Among Jaguars (Panthera onca)

The Southwestern Naturalist, 2010
Abstract This is the first report of cannibalism in a free-ranging population of jaguars (Panthera onca). An encounter among unfamiliar jaguars may have provoked social stress, a behavior reported in other free-ranging carnivores.

Involution of the auditory neuro-epithelium in a tiger (Panthera tigris) and a jaguar (Panthera onca)

Journal of Comparative Pathology, 1984
Numerical atrophy of the hair cells of the organ of Corti of the inner ear in a 14-year-old tiger and a 17-year-old jaguar is described. The decrease in number of sensory hair cells is considered to represent physiological atrophy caused by the process of ageing. The findings are compared with previous observations on man, guinea-pigs, shrews, and bats.

Duration of spermatogenesis and daily sperm production in the jaguar (Panthera onca)

Theriogenology, 2008
The jaguar, like most wild felids, is an endangered species. Since there are few data regarding reproductive biology for this species, our main goal was to investigate basic aspects of the testis and spermatogenesis. Four adult male jaguars were utilized; to determine the duration of spermatogenesis, two animals received an intratesticular injection of

Tungiasis in a free-ranging jaguar (Panthera onca) population in Brazil

Parasitology Research, 2011
Tungiasis is an ectoparasitic disease caused by fleas of the genus Tunga. The disease is reported to occur mostly in human populations. In wildlife, however, the occurrence and impact of this disease remains uncertain. We captured and examined 12 free-ranging jaguars for the presence of Tunga penetrans in the Pantanal region of Mato Grosso do Sul state,
