Virulence of Pertactin-Negative<i>Bordetella pertussis</i>Isolates from Infants, France

31 Jan 2013

Abstract excerpt

Bordetella pertussis isolates that do not express pertactin (PRN) are increasing in regions where acellular pertussis vaccines have been used for >7 years. We analyzed data from France and compared clinical symptoms among infants <6 months old infected by PRN-positive or PRN-negative isolates. No major clinical differences were found between the 2 groups.
