Abstract: Infections caused by Bordetella pertussis (B. Pertusis), have
recently been reported increasingly even in highly immunized populations. This
is a population-based, descriptive study. Nasopharyngeal sampling was performed
in school children between 6–14 years old with coughing for two weeks or more
but without any proved underlying diseases. The specimens were examined for B.
Pertusis and Bordetella parapertussis (B. parapertusis) by Polymerase chain
reaction and culture. Out of 6601 students, 21 (6.40%) children were found to
be positive by polymerase chain reaction assay for B. Pertusis and 6 (2.43%)
children had this test positive for B. parapertusis. B. Pertusis was detected
in the culture of 4 (1.22%) specimens (all culture positive cases were
positive for Polymerase chain reaction too) and B. parapertusis culture was not
found positive at all. The estimated incidence of pertussis in this age group
was 318/100000 and for B. parapertusis was 2/100000. Pertussis has to be
considered as one of the etiologies of prolonged cough in children and adolescents in Iran.
