To address the global spread of Bd it is crucial that a dedicated system is available to collect, map and model the prevalence of infection to aid control measures directed against Bd. We have developed Bd-Maps to be aimed at differing audiences (scientists, policy makers, the public) and we are focussed on addressing a number of questions (spread, epidemiology, evolution, control).

The overarching aim of Bd-Maps is to provide a community-focussed resource. All data is presented in a geographical context facilitating identification of areas of potential spread and temporal analysis allows previous spread to be modelled and used to identify areas of concern. Such analyseswill be directed towards policy makers, resource managers, the general public and the scientific community. All the data on the public site will be downloadable, allowing further analysis and synthesis by interested parties.

Global mapping

A map detailing global incidence of positive Bd collections can be accessed from the frontpage by clicking the 'Maps' link on the right hand menu. .  Clicking on a particular site centres and zooms the map and details all data recorded at that location. Listed for each location are the species found (including links to the IUCN Red list1 and the GAA2 to view distribution patterns), method of detection, publication and date of collection.


Surveillance - see here

Global Summary

Data statistics are available detailing site numbers, countries and species recorded. Countries/species are ranked based on prevalence

More resolved summaries are available as follows: 

1) Country summaries - see here

Any country represented in the database can be viewed through the country summary. Along with a map detailing distribution, summary statistics for sites, samples and species collected, data is returned indicating diagnostic techniques and genotypes if known.  Within country surveillance is undertaken at the species level and country specific-cutoffs can be set by data managers. 

2) Species summaries - see here

The global distribution of any species submitted can be viewed. Statistics are viewable indicating number of individuals, number of sites sampled etc.. All data for the species is listed below a map of distribution and links to the IUCN and GAA are available on a species basis.

Database interrogation - see here

Standard database interrogation tools are available to return data based on a user entered criteria. For example – all isolates not found in USA which have been confirmed using qPCR.


To disseminate information to the community in a timely fashion the Bd site has a BLOG which can be accessed here - - http://spatialepidemiology.blogspot.com

Published articles

A list of relevant articles indexed in PubMed is available as an RSS feed from the front page.  We encourage users to let us know of articles not included and / or relevant articles not in published in the scientific literature (Press and media articles, other BLOG posts, newsgroups etc.) Click here
