The isolation of Pasteurella multocida from several red-necked wallabies (Macropus rufogriseus) with purulent to necrotizing gingivitis, mandibular osteomyelitis, and conjunctivitis in a private zoological park prompted a cross-sectional prevalence study in two zoological collections. The study demonstrated a high prevalence of P. multocida carriage in clinically healthy red-necked wallabies. In one collection (n= 7), P. multocida was isolated from the gingival mucosa of two animals (28.6%) and the conjunctiva of one animal (14.3%). In another collection (n = 29), P. multocida was isolated from the buccal mucosa in two animals (6.9%) and the pharyngeal mucosa of eight animals (27.6%). Multilocus sequence typing showed that sequence types varied among, but were identical within, collections.

Tick-borne haemoparasites, including piroplasms and trypanosomes, are almost ubiquitous in Australian wildlife, with some associated with health impacts to individual animals and declining wildlife populations. An array of ecologically distinct piroplasm and trypanosome species occur throughout Australia although many of these species and their sylvatic ecologies are poorly characterised. Between May 2022 and October 2023, an anecdotally reported localised eastern grey kangaroo () morbidity/mortality event occurred in coastal southern New South Wales, Australia, characterised by animals presenting with blindness, emaciation, lethargy, ataxia, and astasia.

Dental enamels of different species exhibit a wide variety of microstructural patterns that are attractive to mimic in bioinspired composites to simultaneously achieve high stiffness and superior toughness. Non-human enamel types, however, have not yet received the deserved attention and their mechanical behaviour is largely unknown. Using nanoindentation tests and finite element modelling, we investigate the mechanical behaviour of Macropus rufogriseus enamel, revealing a dominating influence of the microstructure on the effective mechanical behaviour and allowing insight into structural dependencies.

Background: We studied the occurrence of two sympatric wallabies, the red-necked pademelon () and the red-legged pademelon () in northeastern New South Wales, Australia in relation to structural habitat attributes. At our study site, both species inhabit closed forest environments and have overlapping distributions, but leaves the forest at night to graze adjacent grassy forest edges whereas remains within the forest and browses forest vegetation. The objectives of the study were to investigate how structural attributes of two forest types, wet sclerophyll forest and rainforest, relate to the fine-scale occurrence of these two wallaby species within the forested environment.

Notamacropus rufogriseus (red-necked wallaby) are in the family Macropodidae, which is the second largest family of marsupials after the family Didelphidae. This study was conducted with the aim of providing a detailed description of the origin and distribution of the brachial plexus in N. rufogriseus.
