Duration of Bordetella pertussis Polymerase Chain Reaction Positivity in Confirmed Pertussis Illness.
نویسندگان
چکیده
Pertussis cases have been increasing in the United States for the past 40 years. Polymerase chain reaction (PCR) testing is now the preferred method of diagnosis, but little is known about duration of PCR positivity. We conducted a pilot study using serial B pertussis PCR testing to determine duration of PCR positivity. Kaplan-Meier survival analysis suggested a median duration of 58 days (interquartile range, 40-110 days).

Bordetella pertussis PCR positivity, following onset of illness in children under 5 years of age.
Bordetella pertussis is a significant cause of respiratory illness and an ongoing public health problem. Pertussis polymerase chain reaction (PCR) testing has been widely utilised since 2001, especially in infants. Uncertainty exists as to how long PCR remains positive following symptom onset. Further information on the time frame for pertussis PCR testing would assist diagnosis, epidemiologica...
متن کاملBordetella pertussis Infection in South African HIV-Infected and HIV-Uninfected Mother–Infant Dyads: A Longitudinal Cohort Study
BACKGROUND There is a paucity of data regarding the burden of Bordetella pertussis in African women and young infants, and particularly the impact of maternal human immunodeficiency virus (HIV) infection thereon. We performed a retrospective analysis of respiratory illness samples from longitudinal cohorts of HIV-uninfected and HIV-infected women and their infants to evaluate the burden of per...
متن کاملDiagnosis of Whooping Cough in Switzerland: Differentiating Bordetella pertussis from Bordetella holmesii by Polymerase Chain Reaction
Bordetella holmesii, an emerging pathogen, can be misidentified as Bordetella pertussis by routine polymerase chain reaction (PCR). In some reports, up to 29% of the patients diagnosed with pertussis have in fact B. holmesii infection and invasive, non-respiratory B. holmesii infections have been reported worldwide. This misdiagnosis undermines the knowledge of pertussis' epidemiology, and may ...
متن کاملAllelic variations between vaccine strains and circulating strains in pxtP of Bordetella pertussis in Iran
Introduction: Despite high level of vaccination against pertussis‚ whooping cough has re-emerged as a health threat, especially in infants. This could be related to expansion of Bordetella pertussis with novel alleles for virulence factors including the pertussis toxin promoter, ptxP3. Compared to ptxp1 strains‚ ptxp3 strains produce more pertussis toxin which results in immune supp...
متن کاملEvidence of Bordetella pertussis infection in adults presenting with persistent cough in a french area with very high whole-cell vaccine coverage.
Although France has had a vaccination program for 40 years, since 1990, an increase in whooping cough cases with parent-infant transmission has been observed. This study prospectively assessed the frequency of Bordetella pertussis infection in adults who consulted general practitioners for a persistent cough without an evident diagnosis. Among 217 patients, 70 (32%) confirmed whooping cough cas...
