Abstract
The prevalence of antibodies to Toxoplasma gondii was determined in three species of domestic and commensal mammals, from Baltimore, Maryland, USA. Crude prevalences of infection were 14.5% in cats (N=650), 32.2% in dogs (N=233), and 49.5% in Norway rats (N=109). Oocysts identical to T. gondii were detected in 0.5% of cat feces. Cats and rats showed antibody prevalence rates which were strongly age-(or some age-related variable) dependent, with the highest rates associated with older animals. Antibody prevalence increased in dogs up to three years of age, then declined slightly in older animals.
