title: Serological study of human toxoplasmosis in Calcutta.
abstract: A total of 248 randomly selected subjects from urban, semiurban and rural areas of Calcutta was studied serologically for the prevalence of antibody to Toxoplasma gondii using latex agglutination technique. Fifty-nine (23.79%) out of these 248 subjects were found to possess anti-toxoplasma antibody. Seropositivity was found to be higher in females (25%) as compared to males (22.32%). Agewise highest positivity (30.5%) for toxoplasma antibody was observed in the third decade and lowest in the first decade of life, though all the age groups were involved by this protozoal infection. Sexwise distribution of anti-toxoplasma antibody showed highest positivity rate in the third decade in males and in the fourth decade in females. Twenty-five per cent of the subjects had history of contact with cat and/or soil and most of the subjects belonged to the middle and low income groups.
