Anne Ballmann

Anne Ballmann is a Wildlife Disease Specialist at the National Wildlife Health Center.

I joined the USGS National Wildlife Health Center as a wildlife disease specialist/field epidemiologist in 2008. I earned my DVM at the University of Tennessee-Knoxville and a PhD in Comparative Medicine-Population Health at North Carolina State University (Raleigh). I’m actively involved in research and multi-agency coordination for bat white-nose syndrome (WNS) and currently serve as the lead for the WNS Diagnostic Working Group as well as on the WNS National Coordination Team.

North American Bat Data Integration

The purpose of this project was to integrate the Bat Banding Program data (1932-1972) and the U.S. and Canada diagnostic data for white-nose syndrome with the USGS Bat Population Data (BPD) Project and provide the bat research community with secure, role-based access to these previously unavailable datasets. The objectives of this project were to: 1) integrate WNS diagnostic data into the BPD (htt

Pseudogymnoascus destructans detections by US county 2013-2020

This data documents the results of sampling for the white-nose syndrome fungus, Pseudogymnoascus destructans (Pd) at the USGS National Wildlife Health Center between 2013-2020. Data are reported on the county level. Locations are accurate to county only. We used data collected at winter locations only (hibernaculum) for this data set.

WNS Summer Surveillance: DATA

Bats occupying hibernacula during summer months may play an important role in the epidemiology of white-nose syndrome (WNS). For example, bats exposed to viable Pseudogymnoascus destructans (Pd), the causative agent of WNS, in late summer could spread the fungus by transmitting it to other bats or to other locations suitable for establishment of new environmental reservoirs. To explore risks for

Long-term Pseudogymnoascus destructans surveillance data reveal factors contributing to pathogen presence

The disease white-nose syndrome (WNS) was first recognized in upstate New York in 2006 and has since spread across much of the United States (U.S.), causing severe mortality in several North American bat species. To aid in the identification and monitoring of at-risk bat populations, we evaluate factors associated with the presence of the causative fungal agent of WNS, Pseudogymnoascus destructans

Recovering individual-level spatial inference from aggregated binary data

Binary regression models are commonly used in disciplines such as epidemiology and ecology to determine how spatial covariates influence individuals. In many studies, binary data are shared in a spatially aggregated form to protect privacy. For example, rather than reporting the location and result for each individual that was tested for a disease, researchers may report that a disease was detecte

Analysis of archival specimens confirms White-nose syndrome in little brown bats (Myotis lucifugus) from New York, USA, in spring 2007

White-nose syndrome (WNS), an emerging fungal disease of North American bats, was first diagnosed in January 2008, although mortality and photo-documentation suggest the disease may have been present earlier. Using archived samples, we describe a definitive case of WNS in little brown bats (Myotis lucifugus) from New York, USA, in spring 2007.

Environmental contamination and unusual snake mortality in an urban national wildlife refuge

The National Wildlife Refuge (NWR) System protects ~150 million acres of land and water in the United States and provides habitat for >2,000 native vertebrates species. Although legally protected, wildlife populations within these refuges can be threatened by anthropogenic activities. The lack of knowledge about such threats has the potential to undermine biodiversity conservation. We investigate
