Th17 cells have critical roles in mucosal defense and are major contributors to inflammatory disease. Their differentiation requires the nuclear hormone receptor RORγt working with multiple other essential transcription factors (TFs). We have used an iterative systems approach, combining genome-wide TF occupancy, expression profiling of TF mutants, and(More)
In 1992, a virus (DPP2209) isolated from sentinel cattle located at Coastal Plains Research Station, latitude 12 degrees 39'S, longitude 131 degrees 20'E, approximately 60 km east of Darwin, Northern Territory. This virus was identified as a serotype of epizootic haemorrhagic disease (EHD) of deer virus previously undescribed in Australia. An additional 17(More)
A recent hypothesis to explain the recurrence of bluetongue disease after winter seasonal absences of the vector has suggested a role for persistent infection of sheep. This report presents combined independent work from two laboratories investigating the possible recovery of Bluetongue virus (BTV) over a protracted period after infection of both sheep and(More)
The susceptibility of cats and dogs to Australian bat lyssavirus (ABLV; genotype VII) was investigated by intramuscular (IM) inoculation of 10(3.7)-10(5) 50% tissue culture infective doses (TCID(50)) of virus followed by observation of experimental animals for up to 3 months post-inoculation (pi). Each experiment also included positive and negative(More)
OBJECTIVE To evaluate and implement molecular diagnostic tests for the detection of lyssaviruses in Australia. DESIGN A published hemi-nested reverse transcriptase polymerase chain reaction (RT-PCR) for the detection of all lyssavirus genotypes was modified to a fully nested RT-PCR format and compared with the original assay. TaqMan assays for the(More)
An antigen-capture ELISA (Ag-ELISA) was developed to detect bluetongue virus (BTV) antigen directly from blood samples. Four blood preparations [whole blood, buffy coat, washed red blood cells (RBC) and plasma] taken pre-inoculation and on days 6 to 9 post-inoculation (PI) were used in the ELISA to study antigenaemia in forty sheep, each experimentally(More)
The flavivirus Japanese encephalitis (JE) virus has recently emerged in the Australasian region. To investigate the involvement of infections with related enzootic flaviviruses, namely Murray Valley encephalitis (MVE) virus and Kunjin (KUN) virus, on immunity of pigs to JE virus and to provide a basis for interpretation of serologic data, experimental(More)
OBJECTIVE To examine the susceptibility of the grey-headed flying fox (Pteropus poliocephalus) to Australian bat lyssavirus (ABL), and to provide preliminary observations on the pathogenesis of the disease in flying foxes. PROCEDURE Ten flying foxes were inoculated intramuscularly with ABL, and four with a bat-associated rabies virus. Inoculated animals(More)
Epizootics of sudden death in tammar wallabies (Macropus eugenii) occurred at six research facilities and zoological gardens in New South Wales, Australia, in late 1998 and at one Queensland research facility in March 1999. There were 120 confirmed tammar wallaby deaths during this period; however, population censuses indicated that up to 230 tammar(More)
Following confirmation that a remote village of approximately 300 inhabitants in northern Lao PDR was hyperendemic for the Neglected Tropical Disease Taenia solium, a pilot human-porcine therapeutic control intervention was implemented between October 2013 and November 2014. Mass drug administration with a three day albendazole 400mg protocol was offered to(More)
