Serosurvey of selected zoonotic agents in polar bears ( Ursus maritimus)
Between 1982 and 1999 blood samples were collected from 500 polar bears ( Ursus maritimus ) captured in the Beaufort and Chukchi seas, to determine the seroprevalence of Brucella species, Toxoplasma gondii , and Trichinella species infections. The bears were classified into four age groups, cubs, ye...

The antibody prevalence for Toxoplasma gondii was 6 per cent, and for Trichinella species 55·6 per cent. The prevalence of antibodies to Trichinella species increased with age (P<0·001).
