Dogs and cats play a role in transmitting toxoplasmosis, larval echinococcosis and larval toxocarosis to man. Toxoplasmosis has spread all over the world, including Hungary. Toxoplasma antibodies can be detected in 0-64 o/o of cat sera. 13 o/o of the human population has been infected by the age of 10, 20 o/o by the age of 20, and 50 o/o when grown up. When examining pregnant women between 1986 and 1990, 69 o/o of them were found to be seropositive. In Hungary toxoplasmosis is a notifiable disease. In 1990, 166 cases were registered. Between 1986 and 1990, 250 blood samples tested for larval echinococcosis exhibited a 1.3-8.3 o/o positivity. The number of cases notified ranged from 8 to 16. In children between the age of 18 months to 3 years, larval toxocarosis is rather frequent. In the sandy and soil samples of the playgrounds in the capital worm eggs occurred in 5.3 and 46.8 o/o, resp. Based on examinations of increasing number for the last 5 years there was a positivity of 25.8 o/o in the first year, followed by a temporary decrease, and a rise to 26.9 o/o in the 5th year
