FC = Feral cat: free-ranging, unowned domestic cats. ML = Mountain lion: wild felids of the species Puma concolor, also commonly called cougars or pumas.
Multi-locus genotypes refer to strains consistent with Type I, II, X or Atypical strains based on the alleles at six target loci determined by concatenated sequence and restriction fragment length polymorphism (RFLP) genotyping data. Toxoplasma gondii DNA was amplified from postmortem brain or tongue tissue samples or from tachyzoite-infected cell cultures of brain tissue by nested PCR analyses. Genotypes consistent with Type I, II, or X based on fewer than six alleles may be atypical genotypes.
Predominant land use was characterized for each carnivore based on sampling location (animals sampled 2006–2009). D = predominantly developed urban, rural, and agricultural lands, U = predominantly undeveloped lands including forests, woodlands, grasslands, shrublands, and wetlands, NA = no spatial data available.
(-) = PCR was performed, but T. gondii DNA was not amplified.
