Spot type net blotch caused by Pyrenophora teres f. maculata (Ptm) has become a prominent disease in Western Australia, as has also occurred elsewhere. The disease has a negative impact on both grain yield and quality resulting from reduced grain size. Lack of resistance and stubble retention are the likely factors in the increased severity of the disease(More)
In-vivo studies of fibrinogen metabolism were carried out using an I-120 labelled preparation of fibrinogen supplied commercially by the Radiochemical Centre, Amerhsham for use in the diagnosis of deep venous thrombosis. These studies show that the material is suitable for obtaining the main metabolic parameters of clinical interest, though degradation(More)
Aspergillus fumigatus infection due to primary infection of the ethmoid sinus affected the brain and orbit of an otherwise healthy elderly woman. Primary nasal sinus infection may be a chronic process analogous to aspergilloma of the lung: it may, however, assume a locally invasive course and spread to the orbit or brain, as in the case described. This form(More)
BACKGROUND The Cervical Health Implementation Project was initiated with the aim of developing and evaluating health system interventions for improving public sector cervical screening services. The project was conducted between January 2001 and May 2003 in three districts in South Africa. This paper describes the districts, interventions and their(More)
Monitoring of filarial parasites in the host and vector has traditionally depended on morphological identification. Recently, species-specific DNA probes have been developed for Brugia malayi, Brugia pahangi and Wuchereria bancrofti. Repeated DNA sequences are useful in developing DNA probes because they evolve more rapidly then coding sequences and their(More)
Citrus canker (caused by Xanthomonas campestris pv. citri Group A) was detected in a pummelo orchard at Lambell’s Lagoon near Darwin in 1991. All citrus trees in the orchard were eradicated. Surveys of horticultural holdings at Lambell’s Lagoon in 1992 failed to detect symptoms of citrus canker. Leaf washings from trees in each orchard failed to detect X.(More)
In February 1994, symptoms consistent with angular leaf spot were found on strawberry plants on three properties in the Kenton Valley region of South Australia. To confirm the identity of the causal organism, bacteria were isolated from affected tissue and processed for analysis using whole genome DNA fmgerprinting and repetitive element polymerase chain(More)
We enumerate the genetic resources for coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco vat. menziesit) in tree improvement programs in the Paci tic Northwest USA and evaluate how they contribute to gene conservation of the species. The first-generation programs include over four million progeny from 33,928 selections planted on 999 test sites.(More)
Barley powdery mildew caused by Blumeria graminis f. sp. hordei is a most devastating disease in Western Australia and elsewhere. The disease has a negative impact on grain yield and quality and, thus, affects its marketability. The detection of pathogen variability has further impacted sustainable barley production. Various isolates have been reported to(More)
Acidovorax avenae subsp. cattleyae is identified as the cause of a common leaf spot and expanding lesion leading to death of Phalaenopsis orchids. The identity of this organism has been confirmed on samples submitted from widely separated locations suggesting the endemic nature of this disease in New South Wales.
