Administration of appropriate antimicrobials and early aggressive supportive treatment is central to the efficacious treatment of neonatal sepsis and has proven to positively influence outcomes. The primary aim of our study was to evaluate microorganism results and antimicrobial sensitivities of neonatal foals with a positive blood culture submitted to our intensive care unit (ICU) during 2005-2022.

Availability of koala release sites could be compromised at times in the future by the increasing incidence of large and intense bushfires due to climate change. In addition, factors such as the fragmentation of koala habitat and increasing urbanisation impose other threats to the long-term survival of the released koala. Our investigation is conducted as a Critically Appraised Topic (CAT) with eight papers selected to be appraised. We highlight three key areas that affect koala rehabilitation and release to fire-affected home sites - the resilience of the koala in recovery, the adaptation ability of the koala upon release and the components of the fire-affected habitat. The evidence shows that the koala is a good candidate for release given that burnt koalas are resilient in rehabilitation and many can recover and then adapt quickly to their release site. Findings from this study indicate that, when the release site is affected by fire, the conditions that are more favourable for koala release are low severity of fire impact, greater distance from urban areas, connection to unfragmented habitat and previous management of predators. These findings can inform wildlife release and rescue as well as government planning and urban development.</p>","PeriodicalId":8661,"journal":{"name":"Australian Veterinary Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142999217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Findings of a recent Australia-wide research project have provided new insights into intestinal parasites (i.e. strongyles and ascarids) and parasite control from the perspectives of Australian horse breeders and equine veterinarians. The published data have revealed recent trends in parasite prevalence and distribution, breeders' and veterinarians' attitudes and perspectives on controlling horse internal parasites, the efficacy of commonly used anthelmintic products and post-treatment egg reappearance periods. These studies have formed the basis of newly developed guidelines managing and treating gastrointestinal nematodes in horses. Tailored for equine veterinarians, these guidelines contain information on target parasites and risk factors for their transmission, as well as practical advice for surveillance, anthelmintic choice, timing of treatment, testing for anthelmintic resistance and managing refugia.

The pilot scale was based on adapting the Measure of Moral Distress for Healthcare Professionals (MMD-HP) to the veterinary context and analysing responses from 643 veterinarians in Australia to create the Measure of Moral Distress for Veterinary Clinicians (MMD-VC). The MMD-VC comprised three sub-scales: (1) team communications that compromise patient care, (2) conflicting client interactions and (3) situations perceived as a personal threat. The additional sources of moral and ethical conflict that were reported by respondents to an open-ended survey question reflected two themes: (1) Animal Health, where the conflict arises from the effect of a situation on the animal patient and (2) Human Interactions, where the conflict relates to interpersonal relationships rather than to the animal patient.
