This plan also broadly considers a number of additional key threatening processes that may affect the host-pathogen dynamic, with potential to result in expression of chytridiomycosis. Content includes: Introduction; Risk assessment; Monitoring to inform triggers for management intervention and emergency response; plus an Action plan.

Dr. Bishop introduced the audience to the amazing life histories of New Zealand's four frog species, and detailed the threats they currently face. The slideshow presentation features many of Dr. Bishop's photos of New Zealand's unique amphibian fauna and there was a question and answer session following the presentation.

A study was recently carried out to determine the distribution of the Chytrid Fungus (Batrachochytrium dendrobatidis) in the Tasmanian Wilderness World Heritage Area (TWWHA), and to identify factors associated with its potential spread. This report was prepared by Matthew Pauza and Michael Driessen, Biodiversity Conservation Branch, Department of Primary Industries and Water, Tasmania in February 2008. http://www.dpiw.tas.gov.au/inter.nsf/Attachments/LJEM-7BY3CR/$FILE/Chytrid%20Report%20Feb%202008.pdf T Grillo 05/07/2010 Keeping it Clean - A Tasmanian field hygiene manual to prevent the spread of freshwater pests and pathogens (March 2010) This manual provides information on how to prevent the spread of freshwater pests and pathogens in Tasmanian waterways, wetlands, swamps and boggy areas. It is intended primarily for people who work in these areas, but also will help recreational visitors to understand the risks and act accordingly. http://www.forestrytas.com.au/uploads/File/pdf/p df2010/keepingitcleanweb.pdf T Grillo 05/07/2010 [PUBLICATION]Vredenburg, V.T. et al., (2010) Dynamics of an emerging disease drive large-scale amphibian population extinctions.

Based on data obtained from live frogs at three major US ports of entry (Los Angeles, San Francisco and New York) from 2000 to 2005. Approximately 28 million individual frogs were imported over the 6-year period. Samples collected from “freshly-imported market frogs found infection with both pathogens in all three cities and all seasons, with an overall infection prevalence of 62% (306/493) and 8.5% (50/588) for B. dendrobatidis and ranaviruses, respectively, by PCR.

Annual Review of Microbiology. 63, 291-310. Abstract: “Batrachochytrium dendrobatidis (Bd) is a chytrid fungus that causes chytridiomycosis in amphibians. Only named in 1999, Bd is a proximate driver of declines in global amphibian biodiversity. The pathogen infects over 350 species of amphibians and is found on all continents except Antarctica. However, the processes that have led to the global distribution of Bd and the occurrence of chytridiomycosis remain unclear. This review explores the molecular, epidemiological, and ecological evidence that Bd evolved from an endemic ancestral lineage to achieve global prominence via anthropogenically mediated spread. We then consider the major host and pathogen factors that have led to the occurrence of chytri 1 2 3 4 5          Submit New Topic
