Lethal fishing hook penetration and line entanglement in an adult bottlenose dolphin (Tursiops aduncus).

The carcass of a 15-year-old female Bottlenose dolphin (Tursiops aduncus) was retrieved from the Port River near Adelaide, South Australia, Australia. The animal was emaciated with five thick nylon fishing lines emerging from the oropharynx attached to a tangle of nylon and monofilament fishing line that also contained wire and eight fishing hooks. The mouth had been cut by the line and a circumferential curvilinear superficial abrasion/indentation from fishing line encircled the entire distal rostrum.

Characteristic "neck collar" injuries in Australian sea lions (Neophoca cinerea) caused by marine debris.

An adult male Australian sea lion (Neophoca cinerea) presented with a deep, almost circumferential, incised wound around the neck caused by a noose formed by a single strand of green nylon rope. The wound extended 4-5 cm deeply through the skin and blubber into skeletal muscle, predominantly on the dorsal surface and left side, but had not involved the airway or major vessels. The edges of the wound were sharply incised and oozing blood with a granulating infected base.

Biological Activity of Piper aduncum extracts on Anticarsia gemmatalis (Hübner) (Lepidoptera: Erebidae) and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae).

Piper aduncum found naturally in the Amazon and southeastern Brazil, is known for its secondary metabolites that have activity on insects. Anticarsia gemmatalis and Spodoptera frugiperda are among the major insect pests associated with agricultural production. This research evaluated the biological activity of hexane, ethyl acetate, and ethanol extracts of P.

Mycobacterium pinnipedii tuberculosis in a free-ranging Australian fur seal (Arctocephalus pusillus doriferus) in South Australia.

This report describes the first case in South Australia, Australia, of Mycobacterium pinnipedii tuberculosis in a free-ranging Australian fur seal (Arctocephalus pusillus doriferus). Severe pyogranulomatous pleuropneumonia with intrahistocytic acid-fast beaded filamentous bacilli was seen on histology. M.

The assessment of lethal propeller strike injuries in sea mammals.

Assessment of injuries in marine mammals may be required to help authorities determine whether human activity was involved. Three cases of marine animal deaths involving propeller blade strikes are reported to demonstrate characteristic features of such cases and diagnostic difficulties that may occur. Case 1: A juvenile New Zealand fur seal (Arctocephalus forsteri) suffered two parallel linear incised wounds of the flank and died following small intestinal herniation.

Mechanisms of deaths in captive juvenile New Zealand fur seals (Arctocephalus forsteri).

Juvenile seals are sometimes encountered in waters around South Australia with injuries and/or diseases that require veterinary treatment. Two cases are reported where apparently stable animals died soon after being rescued due to quite disparate conditions. In Case 1 a juvenile male New Zealand fur seal (Arctocephalus forsteri) was found unexpectedly dead in its enclosure.

Unusual causes of fatal upper aerodigestive tract obstruction in wild Bottlenose Dolphins (Tursiops aduncus).

Necropsy examination of dolphins living in Gulf St Vincent, Australia is routinely undertaken to enable the evaluation of disease processes and to provide rapid medicolegal assessment of any inflicted and/or accidental injuries. Two Indo-Pacific Bottlenose Dolphins (Tursiops aduncus) are reported to demonstrate conditions that may result in unexpected death involving upper airway compromise by quite unusual mechanisms. In the first case an adult male was found with extensive soft tissue trauma suggesting human interaction.
