The aim was to document the trend in pertussis in the Czech Republic (CR) with regard to the infant population under one year of age, which is at highest risk for pertussis. Another point was to answer two questions: 1) whether the recent rise in pertussis cases in the CR is caused by new lineages of B. pertussis, against which the available vaccines are not effective, and 2) whether the circulating strains of B. pertussis are susceptible to antibiotics of choice. Data on pertussis cases were derived from the surveillance programme. Two hundred and sixty-five children under one year of age with laboratory confirmed pertussis, diagnosed between 1997 and 2013, were included in the study. B. pertussis isolates obtained within the surveillance of pertussis were examined by molecular biological methods - MAST (multiantigen sequence typing), MLVA (multilocus variable-number tandem-repeat analysis), and MLST (multilocus sequence typing). B. pertussis strains isolated from patients between 1967 and 2010 were tested for susceptibility to first-line antibiotics for the treatment of pertussis. The analysis of the epidemiological situation confirmed an upward trend in pertussis in the CR since the 1990s in all age categories, including children under one year of age. Nearly 77 % of children acquired pertussis...
