Incidence of Toxoplasma infection in a population of European starlings Sturnus vulgaris from Central England

Abstract

A sample of European starlings, Sturnus vulgaris, culled from a communal roost in a city in Central England, was examined for infection with Toxoplasma. Eleven (8%) of 133 birds were confirmed as infected after horizontal passage of brain homogenate through mice. Serological examination, using the indirect and direct agglutination tests, proved unsatisfactory for screening starlings for Toxoplasma infection. If the proportion of starlings infected with Toxoplasma in this sample is representative of the population as a whole, then this bird could play an important role in the maintenance of the infection in urban environments.
