In January 2006, the TSA sponsored a multidisciplinary visit to determine the causes of mortality in captive hatched/reared juvenile Chitra chitra and assess the reproductive fitness of the adult breeding stock. During the investigation, there were approximately 130 juvenile Chitra chitra alive in the facility. The mortality investigation started with a detailed history of the collection, past water quality testing, diet, husbandry practices, and previous medical problems and diagnostics. Juvenile mortality had been intermittent over the years with deaths usually occurring after a protracted bout of shell disease characterized by pitting, vesicles, ulcers, and weight loss. The team did extensive water quality sampling and analysis of the reservoir and holding water. Physical examinations of both healthy and sick juvenile Chitra were performed. Samples of blood, shell, and feces were obtained for testing at Chulalongkorn University in Bangkok. Shell biopsies from live animals revealed necrotic ulcerative dermatitis with degenerative changes symptomatic of a disseminated infectious process. In addition, necropsy investigations were also done with histopathology when possible. Common gross necropsy diagnoses in the juvenile Chitra (ages 2-3 years) were chronic erosive shell disease, enteric coccidiosis, cystic calculi, and cachexia with ascites. Histopathology confirmed severe catarrhal colitis due to coccidiosis in one animal. Fecal examinations of the enteric contents from numerous deceased juveniles fixed in formalin revealed enteric coccidiosis. Samples of the Chitra feces were collected for parasite identification, but were unable to be identified to genus level. Recommendations are being constructed to reduce parasite transmission and to provide practical therapies in symptomatic animals to reduce morbidity and mortality.
