Cutaneous and Respiratory Lesions in Bushfire-Affected Koalas.

In the wake of increasingly frequent bushfires emerging as a threat to wildlife worldwide, koalas have notably been the most rescued species in Australia. However, our understanding of burns and their severity in koalas is limited; hence, this study investigated the histopathological features and depth of burns in koala skin, as well as the presence of smoke-induced respiratory tract damage. In four bushfire-affected koalas that had been euthanised on welfare grounds, skin burns in various body regions were scored based on clinical appearance as superficial, partial thickness, or full thickness.

An Analysis of Demographic and Triage Assessment Findings in Bushfire-Affected Koalas () on Kangaroo Island, South Australia, 2019-2020.

In the 2019-2020 Australian bushfires, Kangaroo Island, South Australia, experienced catastrophic bushfires that burnt approximately half the island, with an estimated 80% of the koala population lost. During and after the event, rescued koalas were triaged at a designated facility and a range of initial data were recorded including rescue location and date, sex, estimation of age, body condition and hydration, and assessment of burn severity ( = 304 records available). Koalas were presented to the triage facility over a span of 10 weeks, with 50.

Therapeutics in Herd/Flock Medicine.

When treatment is required for a herd/flock health concern, a range of factors must be considered to determine the preferred treatment strategy. If a group treatment strategy is pursued, considerations to optimize the likelihood of safe and effective group treatment include taxon-specific pharmacokinetics/pharmacodynamics, the formulation of prescribed medication, the type and amount of food, the number and type of water sources, enclosure design, size and demography of the group, weather conditions, and health status of individuals in the group. In addition, antimicrobial stewardship principles and relevant legislation/regulation must be at the forefront of decision making.

Horner Syndrome With Ipsilateral Wing Paresis in a Wild, Juvenile Yellow-Tailed Black Cockatoo ().

A juvenile yellow-tailed black cockatoo () was presented with paresis of the right wing, ptosis, and miosis of the right eye; feather erection of the right side of the head and neck; and a penetrating injury over the right pectoral muscle. Temporary reversal of ptosis, miosis, and feather erection after administration of phenylephrine drops confirmed a diagnosis of Horner syndrome. Computed tomographic imaging revealed a fractured rib, traumatic lung lesions, and subcutaneous emphysema.

Psittacid Adenovirus-2 infection in the critically endangered orange-bellied parrot (Neophema chrysogastor): A key threatening process or an example of a host-adapted virus?

Psittacid Adenovirus-2 (PsAdv-2) was identified in captive orange-bellied parrots (Neophema chrysogastor) during a multifactorial cluster of mortalities at the Adelaide Zoo, South Australia, and an outbreak of Pseudomonas aeruginosa septicaemia at the Tasmanian Department of Primary Industries, Parks, Water and Environment captive breeding facility, Taroona, Tasmania. This was the first time that an adenovirus had been identified in orange-bellied parrots and is the first report of PsAdv-2 in Australia. To investigate the status of PsAdv-2 in the captive population of orange-bellied parrots, 102 healthy birds from five breeding facilities were examined for the presence of PsAdv-2 DNA in droppings and/or cloacal swabs using a nested polymerase chain reaction assay.
