The introduction of a new group of dendrobatid frogs to an established captive amphibian collection was followed by several acute mortalities in both resident and introduced frog populations. Chytridiomycosis, caused by Batrachochytrium dendrobatidis, was diagnosed by histology in two of the dead frogs. Following the diagnosis, all amphibians were moved to(More)
The current Australian national maternity reform agenda focuses on improving access to maternity care for women and their families while preserving safety and quality. The caseload midwifery model of care offers the level of access to continuity of care proposed in the reforms however the introduction of these models in Australia continues to meet with(More)
Cloned DNA of the geminivirus wheat dwarf virus (WDV) was successfully used to infect seedling wheat plants. The clone was derived from circular double-stranded viral DNA isolated from naturally infected tissue. The initiation of infection was mediated by Agrobacterium tumefaciens using cloned dimeric WDV genomes in a binary Agrobacterium vector. The WDV(More)
The feasibility to raise nonhuman primate antibodies against selected components of the human immune system was tested. The immunogens were whole cells (human T lymphocytes) or purified, recombinant human proteins (cytokines: TNF alpha or GM-CSF; soluble forms of cell surface antigens: sCD4 or sCD25). Significant immunizations, yielding functionally(More)

Most recombinant human (rh) proteins elicit an immune response in experimental animals. Antibodies are usually detected within 1 to 2 weeks of protein administration. The immunogenicity of rh proteins is an important aspect for both experimental and clinical investigations. The formation of neutralizing antibodies-as shown here for rhIL-3-reduced the(More)
Estrogen receptor negative tumours are unable to respond to antiestrogen therapy. The underlying molecular mechanisms of estrogen receptor negativity are poorly understood. Cytosine mechylation is one of the mechanisms of gene control and previous studies, particularly on breast tumour derived cell lines have suggested that hypermethylation of HpaII(More)
A monomeric clone of double-stranded DNA synthesized in vitro DNA of the geminivirus Digitaria streak (DSV) was subcloned as a tandem dimeric unit into a binary vector of Agrobacterium tumefaciens, creating a plasmid pDS2. Inoculation of digitaria sanguinalis with A. tumefaciens carrying pDS2 resulted in viral infection. The symptoms, virus particles, and(More)
