The koala, the only extant species of marsupial family Phascolarctidae, is classified as 'vulnerable' due to habitat loss and widespread disease. We sequenced koala genome, producing a complete contiguous reference including centromeres. reveal that koala's ability detoxify eucalypt foliage may be expansions within cytochrome P450 gene family, its smell, taste moderate ingestion plant secondary metabolites in vomeronasal receptors. characterized novel lactation proteins protect young pouch...
Abstract Assessing the scope and severity of threats is necessary for evaluating impacts on populations to inform conservation planning. Quantitative threat assessment often requires monitoring programs that provide reliable data over relevant spatial temporal scales, yet such can be difficult justify until there an apparent stressor. Leveraging efforts wildlife management agencies record winter counts hibernating bats, we collated 5 species from 200 sites across 27 U.S. states 2 Canadian...
Abstract Mammalian three-dimensional (3D) enteroids mirror in vivo intestinal organisation and are powerful tools to investigate cell biology host–pathogen interactions. We have developed complex multilobulated 3D chicken from embryonic villi adult crypts. These avian develop optimally suspension without the structural support required produce mammalian enteroids, resulting an inside-out enteroid conformation with media-facing apical brush borders. Histological transcriptional analyses show...
Devil facial tumour disease (DFTD) is a fatal, transmissible malignancy that threatens the world's largest marsupial carnivore, Tasmanian devil, with extinction. First recognised in 1996, DFTD has had catastrophic effect on wild devil numbers, and intense research efforts to understand contain have since demonstrated clonal cell line transmitted by allograft. We used chromosome painting gene mapping deconstruct karyotype determine rearrangements involved carcinogenesis. Chromosome three...

Abstract Conservation breeding programmes have become widespread as natural habitats shrink, and been historically managed using pedigree data an assumption that population founders are unrelated. Molecular genotyping is able to determine founder relatedness, but rarely used. To empirically test the impact of assuming be unrelated, we utilized from 203 founding individuals 11 subsequent years records for Tasmanian devil ( Sarcophilus harrisii ) insurance population. We integrated molecular N...
Abstract The T asmanian devil ( S arcophilus harrisii ) is threatened with extinction due to the spread of facial tumour disease. Polymorphisms in immune genes can provide adaptive potential resist diseases. Previous studies diversity at loci wild species have almost exclusively focused on major histocompatibility complex MHC ); however, these only account for a fraction gene diversity. Devils lack functionally important immunity loci, including and Toll‐like receptor genes. Whether there...
Avian pathogenic Escherichia coli (APEC) cause severe respiratory and systemic disease in chickens, commonly termed colibacillosis. Early immune responses after initial infection are highly important for the outcome of infection. In this study, early interactions between GFP-expressing APEC strains serotypes O1:K1:H7 O2:K1:H5 phagocytic cells lung CSF1R-reporter transgenic chickens were investigated. express fluorescent protein under control elements CSF1R promoter enhancer, such that...

The platypus is a venomous monotreme. Male platypuses possess spur on their hind legs that connected to glands in the pelvic region. They produce venom only during breeding season, presumably fight off conspecifics. We have taken advantage of this unique seasonal production compare transcriptomes in- and out-of-season glands, conjunction with proteomic analysis, identify previously undiscovered genes. Comparison revealed distinct gene expression profiles are consistent changes gland...
ABSTRACT The Tasmanian devil is under threat of extinction due to the transmissible facial tumor disease (DFTD). This fatal an allograft that does not induce immune response, raising questions about activity cells. T and B cell analysis has been limited by a lack antibodies, hence need produce such reagents. Amino acid sequence revealed CD4, CD8, IgM, IgG were closely related other marsupials. Monoclonal antibodies produced against generating bacterial fusion proteins. These, commercial CD1a...
Abstract Production of milk is a key characteristic mammals, but the features lactation vary greatly between monotreme, marsupial and eutherian mammals. Marsupials have short gestation followed by long period, constituents across lactation. are born immunologically naïve rely on their mother’s for immunological protection. Koalas ( Phascolarctos cinereus ) an iconic Australian species that increasingly threatened disease. Here we use mammary transcriptome, two proteomes koala genome to...
Introduction Highly pathogenic avian influenza (HPAI) viruses, such as H5N1, continue to pose a serious threat animal agriculture, wildlife and public health. Controlling mitigating this disease in domestic birds requires better understanding of what makes some species highly susceptible (such turkey chicken) while others are resistant pigeon goose). Susceptibility H5N1 varies both with strain; for example, that tolerant most strains, crows ducks, have shown high mortality emerging strains...
Abstract Enteroids are miniature self-organising three-dimensional (3D) tissue cultures which replicate much of the complexity intestinal epithelium. We recently developed an apical-out leukocyte-containing chicken enteroid model providing a novel physiologically relevant in vitro tool to explore host–pathogen interactions avian gut. However, consistency and culture stability have not yet been fully explored at transcript level. In addition, causes for inability passage enteroids were...

Tasmanian devil (Sarcophilus harrisii) pouch young, like other marsupials, are born underdeveloped and immunologically naïve, unable to mount an adaptive immune response. The mother's milk provides nutrients for growth development as well providing passive immunity. To better understand response in this endangered species, we set out characterise the genes involved immunity by sequencing annotating transcriptome of a sample collected during mid-lactation. At mid-lactation expect young have...
