Number and percentage of pertactin (Prn)–negative Bordetella pertussis isolates in Australia, 2008–2012. During this period, 320 B. pertussis isolates obtained in New South Wales, Queensland, South Australia, Victoria, and Western Australia were identified as expressing prn or not expressing prn by using Western immunoblotting. The increasing percentage of prn-negative isolates each year during 2008–2012 was 5%, 12%, 23%, 53%, and 78% respectively. Data for individual states and years can be fou

Gray bars indicate number of isolates expressing prn, and white bars indicate number of isolates not expressing prn. Error bars indicate 95% CIs.
