| fate and analysis of endocrine disrupting chemicals in some sewage treatment plants in australia. | there are limited studies on the fate and levels of endocrine disrupting chemicals in sewage treatment plants in australia. research undertaken in europe and north america has shown biologically significant levels of both oestrogenic and androgenic chemicals in sewage effluent. the aim of this work was to determine the oestrogenic and androgenic activities of raw and treated sewage from sewage treatment plants run by midcoast water, new south wales, australia. oestrogenic and androgenic activiti ... | 2008 | 19092195 |
| isolates of cryptococcus neoformans from infected animals reveal genetic exchange in unisexual, alpha mating type populations. | sexual reproduction and genetic exchange are important for the evolution of fungal pathogens and for producing potentially infective spores. studies to determine whether sex occurs in the pathogenic yeast cryptococcus neoformans var. grubii have produced enigmatic results, however: basidiospores are the most likely infective propagules, and clinical isolates are fertile and genetically diverse, consistent with a sexual species, but almost all populations examined consist of a single mating type ... | 2008 | 18552280 |
| clonality and recombination in genetically differentiated subgroups of cryptococcus gattii. | cryptococcus gattii is a pathogenic yeast that together with cryptococcus neoformans causes cryptococcosis in humans and animals. high numbers of viable c. gattii propagules can be obtained from certain species of australian eucalyptus camaldulensis trees, and an epidemiological link between eucalyptus colonization and human exposure has been proposed. however, the highest prevalence of c. gattii cryptococcosis occurs in papua new guinea and in regions of australia where the eucalypt species imp ... | 2005 | 16087745 |
| determination of the optimum incubation period of continuously monitored blood cultures from patients with suspected endocarditis or fungaemia. | it is routine practice to prolong the incubation period of blood cultures from patients with suspected subacute bacterial endocarditis (sbe) or fungal infection. the protocol in this laboratory required 28 days incubation with weekly subcultures. following the introduction of automated continuously monitored blood culture instruments, the duration of incubation for specimens from these categories of patients was reviewed. | 2002 | 12009100 |
| microbial species associated with different sections of broccoli harvested from three regions in australia. | the microbial populations associated with the different sections of broccoli harvested from three locations in australia were studied during storage at 5, 15 and 20 degrees c. bacterial and yeast populations associated with the outer florets and cut surfaces of the stem were generally 10-fold or more higher than those associated with inner florets or non-cut stems, respectively. the predominating bacterial species varied with the origin of the broccoli. pseudomonas fluorescens, ps. corrugata and ... | 2000 | 11014518 |
| the ecological role of killer yeasts in natural communities of yeasts. | the killer phenomenon of yeasts was investigated in naturally occurring yeast communities. yeast species from communities associated with the decaying stems and fruits of cactus and the slime fluxes of trees were studied for production of killer toxins and sensitivity to killer toxins produced by other yeasts. yeasts found in decaying fruits showed the highest incidence of killing activity (30/112), while yeasts isolated from cactus necroses and tree fluxes showed lower activity (70/699 and 11/1 ... | 1987 | 3690423 |
| calbistrin e and two other new metabolites from an australian isolate of penicillium striatisporum. | an australian isolate of penicillium striatisporum collected near shalvey, new south wales, exhibited selective antifungal activity against candida albicans versus saccharomyces cerevisiae. bioassay-directed fractionation yielded members of the rare class of fungal metabolites known as the calbistrins. these included a new example of this structure class, calbistrin e (1), as well as the known polyenes calbistrin c (2) and deformylcalbistrin a (3). also recovered from p. striatisporum were new t ... | 2005 | 15844954 |
