Abstracts: Searching for Lyme borreliosis in Australia: results of a canine sentinel study

BACKGROUND: Lyme borreliosis is a common tick-borne disease of the northern hemisphere that is caused by bacterial spirochaetes of the Borrelia burgdorferi (sensu lato) (Bbsl) complex. To date, there has been no convincing evidence for locally-acquired Lyme borreliosis on the Australian continent and there is currently a national debate concerning the nature and distributions of zoonotic tick-transmitted . . . → Read More: Abstracts: Searching for Lyme borreliosis in Australia: results of a canine sentinel study

Devil vaccine a step closer

The results of an international study published recently in Scientific Reports has confirmed the fatal facial tumour disease that has decimated populations of Tasmanian devils in the wild for over 20 years, can be cured using immunotherapy.

Led by the University of Tasmania’s Menzies Institute for Medical Research, the study involved scientists from the Universities of Sydney, Southampton, Southern Denmark and Cambridge, as well as those from UTAS’s School of Medicine, the Walter and Eliza Hall Institute of Medical Research, and CSL Ltd.

The aim of the study was to ‘explore immunisation protocols to enhance protective responses against DFTD’, but due to devils’ endangered status, only a limited number of animals are available for research purposes. This five-year trial, that tested four immunisation protocols sequentially, was therefore restricted to nine healthy and genetically different animals, some of which had reached an advanced age.

Bisphenol A (BPA) in the serum of pet dogs following short-term consumption of canned dog food and potential health consequences of exposure to BPA

Bisphenol A (BPA) is a widely present endocrine disruptor chemical found in many household items. Moreover, this chemical can bioaccumulate in various terrestrial and aquatic sources; thereby ensuring continual exposure of animals and humans. For most species, including humans, diet is considered the primary route of exposure. However, there has been little investigation whether commercial-brands of dog foods contain BPA and potential health ramifications of BPA-dietary exposure in dogs. We sought to determine BPA content within dog food, whether short-term consumption of these diets increases serum concentrations of BPA, and potential health consequences, as assessed by potential hematological, serum chemistry, cortisol, DNA methylation, and gut microbiome changes, in dogs associated with short-term dietary exposure to BPA.

USyd, UC Davis strengthen collaborative ties

Cameron Carter and Michael Spence AC signing the agreement.

A new agreement between the University of Sydney and the University of California, Davis will see academics benefit from new access to research collaborations and shared funding.

In February, leaders from both institutions joined a partnership signing event.

Vice-Chancellor for Research Professor Cameron Carter of UC Davis and Vice-Chancellor and Principal Michael Spence AC both highlighted the fact that UC Davis has research expertise which greatly complements areas of research strength at Sydney.

“We are very excited about this partnership agreement, particularly for the areas of agriculture and veterinary science,” Spence said. Continue reading USyd, UC Davis strengthen collaborative ties

Effects of the truck suspension system on animal welfare, carcass and meat quality traits in pigs

The objective of this study was to assess the effects of two types of commercial suspension (leaf-spring (LS) vs. air suspension (AS)) installed on two similar double-decked trucks on blood cortisol and lactate concentration, lairage behavior, carcass skin lesions and pork quality traits of 120 crossbred pigs. The suspension type neither influenced pig behaviour in lairage . . . → Read More: Effects of the truck suspension system on animal welfare, carcass and meat quality traits in pigs
