INTESTINAL TYMPANY AND VOLVULUS IN CENTRAL AMERICAN RIVER TURTLES ().

Ten cases of small intestinal tympany with or without volvulus were documented in Central American river turtles (). These turtles were under managed care at the Philadelphia Zoo in Philadelphia, PA, USA, with one case followed after transfer to a different institution. The primary clinical presentation was abnormal buoyancy in nearly all cases (9/10) and anorexia in two cases (2/10).

Comparing different strategies to reduce hepatocellular damage in obese common marmosets (Callithrix jacchus).

Background: Obesity in common marmosets (Callithrix jacchus) can lead to various liver pathologies. In other species, reduced caloric intake and weight loss improve prognosis, and, often, hepatoprotectants are used to halt or reverse hepatocellular damage from fat deposition in the liver. There are no published therapies for reducing hepatocellular damage in obese marmosets.

RETROSPECTIVE REVIEW OF UROLITHIASIS-RELATED MORBIDITY AND MORTALITY IN ASIAN COLOBINE MONKEYS.

Obstructive and incidental urolithiasis cases were evaluated in 5 Asian colobine monkey species (= 21 individuals) that included 12 silvery langurs (), 6 spectacled langurs (), 1 Javan langur (), 1 François' langur (), and 1 red-shanked douc langur () from eight zoologic institutions. All institutions that responded were Association of Zoos and Aquariums, European Association of Zoos and Aquaria, or World Association of Zoos and Aquariums accredited. Males were more commonly represented in the total number of cases (86%), and all cases of obstructive urolithiasis occurred in males.

Metastatic Mixed Germ Cell Tumour with Embryonal Carcinoma and Choriocarcinoma in a Female Eurasian Harvest Mouse (Micromys minutus).

Mixed germ cell tumours occur rarely in veterinary species. This report describes a case of metastatic mixed germ cell tumour in a female Eurasian harvest mouse (Micromys minutus). The tumour was extensive in one ovary and the uterus, and was characterized by two distinct tumour cell populations with features typical of embryonal carcinoma (EC) and choriocarcinoma (CC).

Molecularly Confirmed Acute, Fatal Sarcocystis falcatula Infection in the Rainbow Lorikeets ( Trichoglossus moluccanus) at the Philadelphia Zoo.

The protozoan parasite Sarcocystis falcatula is an important cause of clinical disease in several avian intermediate hosts. The host range of S. falcatula is wide, and numerous outbreaks of acute sarcocystosis have been reported in passerine and psittacine birds in captivity in the Americas.
