Background. All US women are recommended to receive a tetanus, diphtheria, and acellular pertussis (Tdap) vaccine at 27–36 weeks gestation during each pregnancy to reduce the risk of pertussis to their infants. The impact of this strategy on severity of disease among infected infants has not been evaluated. Methods. We use a retrospective cohort study design evaluating whether...

Clinical specimens from 9 states during 2008–2010 were tested by PCR for Bordetella pertussis and Bordetella parapertussis. Of the positive samples, 13.99% were identified as B. parapertussis. It was concluded that B. parapertussis infections are more common than previously realized and contribute to cases thought to be vaccine failures.

In populations without immunization, pertussis is a high-incidence, endemic disease with cyclic epidemic peaks occurring every 2–5 years. The universal use of pertussis vaccines in children results in a marked reduction in incidence, but the frequency of disease cycles does not lengthen. This indicates that the organism (Bordetella pertussis) remains prevalent in the population...
Pertussis is a frequent and significant illness in adults. Because acellular pertussis vaccines for use in adolescents and adults have now been developed, it is important to compare serologic responses in adults after infection with serologic responses in adults after vaccination. We measured IgG and IgA antibodies to 4 Bordetella pertussis antigens at ∼6-month intervals for 28...
Existing clinical case definitions of pertussis are decades old and based largely on clinical presentation in infants and children, yet an increasing burden is borne by adolescents and adults who may manifest distinct signs/symptoms. Therefore, a “one-size-fits-all” clinical case definition is no longer appropriate. Seeking to improve pertussis diagnosis, the Global Pertussis...
A subanalysis of a recent cohort efficacy trial of a pertussis vaccine was performed to determine its efficacy against cough illnesses due to Bordetella parapertussis infections. Infants received four doses of either the Lederle/Takeda acellular pertussis component diphtheria and tetanus toxoids and pertussis (DTaP) vaccine or the Lederle whole-cell component diphtheria and...
Presence of antibody to adenylate cyclase toxin (ACT) has been noted following Bordetella pertussis infection. Because ACT is not presently in any acellular pertussis vaccines, it has been considered as a possible antigen to use in B. pertussis diagnostic enzyme-linked immunosorbent assay (ELISA) studies. We determined antibody to B. pertussis ACT by ELISA and Western blot tests...
Banked acute-phase and convalescent-phase serum samples from a previous study of respiratory illness in university students were examined for significant (≥2-fold) increases in ELISA titers of IgA and IgG antibody to Bordetella pertussis filamentous hemagglutinin, pertactin, and fimbriae-2 and ≥4-fold titer increases to agglutinogens by agglutination. ELISA titers of antibody to...
A serological study to determine the frequency of Bordetella pertussis infection in 100 adults aged ≥65 years was carried out over a 3-year period. Ten serum samples (collected every 4 months) from each subject were examined for IgA and IgG antibodies to the following B. pertussis antigens: pertussis toxin (PT), filamentous hemagglutinin (FHA), pertactin, and fimbriae-2. A ≥2...
Peripheral blood polymorphonuclear leukocytes, mononuclear cells, and plasma and nasopharyngeal specimens were obtained from 6 subjects with persistent symptoms following rubella immunization, 1 subject with persistent symptoms following rubella, 11 children with juvenile rheumatoid arthritis, 17 recently immunized control subjects, and 1 control subject with acute clinical...
Serum specimens were obtained from all subjects in the adolescent and adult acellular pertussis (aP) vaccine efficacy trial before and after immunization to study the prevalence of IgG and IgA antibody and geometric mean titers to 4 Bordetella pertussis antigens. Of 1793 adolescents and adult subjects who received aP vaccine, only 20%, 68%, 59%, and 39% had concentrations of IgG...
Background. Acellular pertussis (aP) booster immunizations have been recommended for adolescents and older persons to enhance long-term protection and to possibly reduce community transmission of infections. Methods. This was a multicenter, randomized, double-blind vaccine trial in which one-half of the subjects received aP vaccine and one-half received hepatitis A vaccine...
Background. Each year, Bordetella pertussis infection causes an estimated 294,000 deaths worldwide, primarily among young, nonvaccinated children. Approximately 90% of all deaths due to pertussis in the Unites States occur in young infants. These children often develop intractable pulmonary hypertension; however, the pathophysiologic mechanism responsible for this complication...

A serological study was undertaken to investigate infections in active-duty United States soldiers with illnesses characterized by prolonged, afebrile, nonproductive coughs. Fifty-four soldiers were enrolled with such illness of ≥2 weeks' duration (case patients) along with 55 well soldiers (control subjects). Serum samples were tested for IgG and IgA antibody to 3 Bordetella...
