We identified seven Leptospira serovars in wildlife and the presence of leptospiral DNA in water sources at a natural area within a fragmented habitat in Illinois, USA. These serovars have been implicated in domestic animal and human leptospirosis, a reemerging zoonotic disease, whose reservoirs include wildlife and domestic animals. We live trappe...

Understanding the success of habitat generalist species requires knowledge of how individuals respond to stressors that vary across habitats within landscapes. Habitat structure can affect stress by altering predation risk, conspecific densities, and densities of heterospecific competitors. Increased demand for biofuels will alter habitat structure...

Toxic minerals and endocrine disruptors contaminants (EDCs) can impact both human and wildlife health. We performed a quantitative assessment of minerals and EDCs in river otters (Lontra Canadensis) in Illinois, and compared them to historical data in the same or similar species. Liver samples were collected from 13 Illinois river otters that died...

Organohalogenated compounds (OHC) are of global concern because of their neurotoxic properties. The North American river otter (Lontra canadensis) is a sentinel species, occupying the highest trophic position in the aquatic ecosystem of Illinois. We analyzed concentrations of various OHCs as environmental contaminants in livers of 13 river otters i...

We conducted a cross-sectional study from 2008 to 2009 to evaluate the occurrence of feral and wild cats and the risk of Toxoplasma gondii infection in terrestrial wildlife in a natural area in Illinois, USA. Felids are definitive hosts for T. gondii and cats are a key component of rural and urban transmission of T. gondii. We selected four forest...

Increasing urbanization has important consequences for wildlife, including the potential for higher prevalence of diseases within "urban adapter" species exposed to spillover from domestic animals. We investigated whether prevalence of antibodies to Toxoplasma gondii in woodchucks (Marmota monax) was related to urbanization in a Midwestern landscap...

Cats and the risk of Toxoplasma gondii infection in terrestrial wildlife: A measure of ecosystem health.
Article
A 2 year cross-sectional study was conducted to evaluate the occurrence of feral and wild cats and the risk of Toxoplasma gondii infection in terrestrial wildlife in a natural area in Piatt County, Illinois. Cats are the definitive host for T. gondii and are a key component of rural and urban transmission of T. gondii to humans, livestock, pets, an...
