title: The prevalence of toxoplasmosis among inhabitants of the Niger Delta.
abstract: Blood samples from 1,650 inhabitants of the Niger Delta were examined for Toxoplasma antibodies by the Sabin--Feldman dye-test. Of that number, 972 (58.9%) presented significant antibody titres. The prevalence rates of the infection varied among different age groups. The highest prevalence rate was recorded among 16-20 years age group (75.3%) and the lowest among inhabitants over 50 years old. Children 1-5 years old had a relatively high prevalence rate (66.0%), with a proportionately higher dye-test antibody titres. More females (64.8%), than males (53.0%) were infected. Also more farmers than people in other occupations in the area were found to be infected. These observations are briefly discussed in relation to the known epidemiology of toxoplasmosis.
