Abstract

Background and purpose: BORDETELLA PERTUSSIS is a gram negative and obligate aerobic bacteria that is cause of whooping cough and is exclusively a human pathogen. In the last decade increasing rate of pertussis was observed. Despite the importance of pertussis as a contagious disease enough information does not exist regarding its incidence rate in Iran. In this research pertussis suspicious specimens were collected from different provinces of Iran in 2009-2010 and then were studied.Materials and methods: A total of 1084 sample from nasopharyngeal secretion or nasal of patients with coughing more than two weeks were collected from different provinces of Iran and were sent to microbiology unit of pertussis reference laboratory in Pasteur institute of Iran. The isolation was done through culturing method. All samples were inoculated through swab on pertussis charcoal agar and Bordet-Gengou plates containing (40 mg/ml) cephalexin antibiotic and once without it. Then the suspected colonies were gram stained and complementary tests was done if colonies were identified as B. pertussis, B. parapertussis.Results: From the total of 1084 samples 12 inoculated samples were positive (1.1%) of which 11 samples were B. pertussis and one sample was B. parapertussis. Among positive CULTUREs, three cases were the patients who were below 2 months, six cases related to individuals from two months to two years of age, two cases related to those aged between two and 10 years old and one patient was over 10 years of age. Nine cases of positive CULTURE specimens were vaccinated and seven cases were the patients who used antibiotics.Conclusion: Results of this study indicated that most isolated strains in Iran were related to those aged between two months to two years old. According to clinical and paraclinical problems regarding whooping cough in Iran and also low sensitivity of culturing method to diagnose Bordotella, complementary methods such as Real-Time PCR should be used.
