mucormycosis in a free-ranging green tree frog from australia.mucor amphibiorum is reported for the first time from a free-ranging native amphibian, a green tree frog (litoria caerulea) from queensland, australia. the nasal cavity was largely replaced by granulomatous inflammatory tissue, and most internal organs had nodular granulomas. typical mother and daughter sphaerules of m. amphibiorum occurred in these nodules which were due to granulomatous inflammation as well as areas of more active mixed inflammation with necrosis. tissue homogenate from the sp ...19979391982
salmonelliasis in wildlife from queensland.during a 20 yr period (1978 to 1998), 233 isolates of salmonella spp. were cultured from 179 wildlife animals (representing 25 species), 32 crocodile (crocodylus porosus) eggs and six crocodile nesting sites, and represented 59 different serotypes. salmonella serotype virchow, the major serotype infecting humans in north queensland, (australia) was common in macropodids, but was not found in reptiles and was isolated only once from cane toads (bufo marinus). investigations of human cases of salm ...200111310872
the ecological genetics of introduced populations of the giant toad, bufo marinus. iv. gene flow estimated from admixture in australian populations.allele frequency variation is described at nine polymorphic enzyme loci in 21 samples from populations of the introduced giant toad, bufo marinus, in the region of townsville in north queensland, australia. some of these populations appear to have been established through the introgression of other populations that previously had been isolated. comparisons of allele frequencies at three polymorphic loci between the introgressed populations and the original populations are used to obtain admixtur ...19863084402
possible differences in pathogenicity between cane toad-, frog- and platypus-derived isolates of mucor amphibiorum, and a platypus-derived isolate of mucor circinelloides.platypuses (ornithorhynchus anatinus) in the north of the island state of tasmania, australia, suffer from a serious disease called ulcerative mycosis, which is responsible for high morbidity and, presumably, mortality rates in areas where it occurs. the disease is caused by the dimorphic fungus mucor amphibiorum, which is also found in queensland, new south wales and victoria. however, it does not cause disease in platypuses in those states. it has been previously reported that a closely relate ...200515832556
acute thermal stressor increases glucocorticoid response but minimizes testosterone and locomotor performance in the cane toad (rhinella marina).climatic warming is a global problem and acute thermal stressor in particular could be considered as a major stressor for wildlife. cane toads (rhinella marina) have expanded their range into warmer regions of australia and they provide a suitable model species to study the sub-lethal impacts of thermal stressor on the endocrine physiology of amphibians. presently, there is no information to show that exposure to an acute thermal stressor could initiate a physiological stress (glucocorticoid) re ...201424643017
