Abstract: | The immunity state towards poliomyelitis has been evaluated in 506 young immigrants coming from European and extraeuropean countries without immunization history. Polioviruses 1, 2 and 3 antibodies were detected in 97% of the serum samples. 15 subjects did not have detectable antibodies at 1:2 dilution for one or two polioviruses. Out of these subjects, 6 (coming mostly from East European Region) were negative in the undiluted serum too. On the whole, GMTs for type 1 (43,29) and 2 (41,9) appeared higher than those for type 3 (33,6). Moreover there are differences among the origin countries; in fact, GMTs more elevated for type 1 and 3 (74,6 and 49,6 respectively) have been observed in the subjects coming from the African region, as well in those coming from the American region. |
