CASE SERIES: Avian mycobacteriosis is a significant disease of a wide range of bird species worldwide. The most common causative agent, Mycobacterium avium, is reported to also infect a range of mammals, including humans. Of 11 brolgas (Antigone rubicunda) submitted to the University of Melbourne for postmortem examination over a 10-year period, 7 were diagnosed with mycobacteriosis. All were from a wildlife park and kept in permanent enclosures as part of a breeding program. Most of the brolgas with mycobacteriosis were in poor body condition and had widely disseminated granulomas throughout the body, especially within the liver, spleen and gastrointestinal tract...

BACKGROUND: Veterinarians are required to interpret the significance of radiographic findings for sale, soundness and future racing performance of weanling and yearling Thoroughbreds. We investigated the prevalence and radiographic appearance of slab fractures of the third (T3) and central tarsal (Tc) bones. METHODS: Weanling and yearling horses with complete or incomplete T3 or Tc fracture were identified by searching a database of radiographs. The prevalence and radiographic appearance at initial diagnosis and after continued pasture turnout, as well as prognosis for racing, of fractures of T3 and Tc were determined...

CASE REPORTS: Five dogs (4 with severe carpal contracture, 1 with a chronically infected carpal joint) underwent antebrachiometacarpal arthrodesis. Excision of all carpal bones, except the accessory carpal bone, was done, either because of persistent infection or to allow the manus to be arthrodesed in a functional position. All five dogs developed varying degrees of soft tissue swelling of the surgical site following surgery. All five arthrodeses achieved complete osseous union within 4-67 weeks...

BACKGROUND: Cefovecin has a long duration of antibiotic activity in cats and dogs, somewhat attributable to its high plasma protein binding. AIMS: To determine the cefovecin binding to plasma proteins in vitro in selected Australian marsupials and to quantify the change in cetovecin concentration over time following subcutaneous injection in koalas. METHODS AND RESULTS: Various cefovecin concentrations were incubated with plasma and quantified using HPLC...

With the commercial release in Australia in 2004 of a vaccine against feline immunodeficiency virus (FIV; Fel-O-Vax FIV®), the landscape for FIV diagnostics shifted substantially. Point-of-care (PoC) antibody detection kits, which had been the mainstay for diagnosing FIV infection since the early 1990s, were no longer considered accurate to use in FIV-vaccinated cats, because of the production of vaccine-induced antibodies that were considered indistinguishable from those produced in natural FIV infections...

BACKGROUND: Studying wild animals in situ is fundamental to collecting baseline information, but generally they need to be immobilised for examination, sampling, marking and/or equipping with tracking apparatus. Capturing wild animals is inherently risky and there is a need for immobilisation methods that are safe for both the animals and researchers. METHODS: A total of 16 free-ranging swamp buffalo (Bubalus bubalis) were chemically captured by dart for the application of satellite tracking collars in tropical northern Australia; 7 animals were anesthetised with a thiafentanil-etorphine-azaperone (TEA) combination and 9 animals with a thiafentanil-azaperone (TA) combination...
