title: Association of cats and toxoplasmosis.
abstract: In 1970, immunofluorescent toxoplasma dye titers were measured on 265 individuals aged 30 years and older from Washington County, Maryland. Characteristics of the individuals were determined from a private census conducted in this area in 1963. Titers at 1:16 dilution or higher were found in 38.5%. A strong positive association was found with increasing age, possession of farm animals, and residence in an older house; a strong negative association was found with possession of cats. These data are not consistent with laboratory evidence that cate are definitive hosts and disseminators of toxoplasma.
