Primary urinary bladder haemangiosarcoma in a captive saddleback tamarin (Saguinus fuscicollis).

Background: A captive adult male saddleback tamarin, Saguinus fuscicollis, was lethargic, unresponsive to its surrounding and died before medical care.

Methods: Necroscopic, histopathological and immunohistochemical examinations were performed.

Results: Neoplastic spindle cells of the urinary bladder were positive for antifactor VIII antibody.

Relationship of creatine kinase, aspartate aminotransferase, lactate dehydrogenase, and proteinuria to cardiomyopathy in the owl monkey (Aotus vociferans).

Background: The purpose of this study was to determine serum reference values for creatine kinase (CK), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in captive-born and wild-caught owl monkeys to assess their usefulness for diagnosing myocardial disease.

Methods: Blood samples were collected for CK, AST and LDH determinations. In addition, urine samples were collected and semiquantitative tests performed.

Clinical, humoral, and pathologic findings in adult alpacas with experimentally induced Corynebacterium pseudotuberculosis infection.

Objective: To experimentally infect adult alpacas by ID inoculation of Corynebacterium pseudotuberculosis, follow the clinical and pathologic course of disease, and study the humoral response to infection.

Animals: 13 adult alpacas.

Procedures: 9 alpacas were inoculated with 1.
