Intracardiac Induced Ventricular Fibrillation for the Euthanasia of Sheep.

Euthanasia is the humane termination of an animal's life and an important consideration for scientists, veterinarians, regulators, and others contemplating investigations involving animals. Techniques for euthanasia must induce the most rapid, painless, and distress-free death possible. This study investigated the effectiveness of direct current induction of ventricular fibrillation for the euthanasia of sheep after a primary study in which artifacts or chemical contamination from injectable euthanasia agents were undesirable.

Noninvasive test for tuberculosis detection among primates.

Traditional testing methods have limited epidemiologic studies of tuberculosis among free-living primates. PCR amplification of insertion element IS6110 of Mycobacterium tuberculosis from fecal samples was evaluated as a noninvasive screening test for tuberculosis in primates. Active tuberculosis was detected among inoculated macaques and naturally exposed chimpanzees, demonstrating the utility of this test.
