Virulence of Pertactin-Negative Bordetella pertussis Isolates from Infants, France
نویسندگان
چکیده
Bordetella pertussis isolates that do not express pertactin (PRN) are increasing in regions where acellular pertussis vaccines have been used for >7 years. We analyzed data from France and compared clinical symptoms among infants <6 months old infected by PRN-positive or PRN-negative isolates. No major clinical differences were found between the 2 groups.

Virulence Factors Variation Among Bordetella Pertussis Isolates in Iran
Pertussis is still endemic and the recently resurgence of the disease caused by Bordetella pertussis has been shown in many countries. The polymorphism of the virulence genes of B. pertussis and lack of any information about the allelic variation between the Iranian isolates promotes us to analysis of the genes encoded virulence factors including ptxS1, prn, fim3 and cya to understand the diffe...
متن کاملNew Data on Vaccine Antigen Deficient Bordetella pertussis Isolates
Evolution of Bordetella pertussis is driven by natural and vaccine pressures. Isolates circulating in regions with high vaccination coverage present multiple allelic and antigenic variations as compared to isolates collected before introduction of vaccination. Furthermore, during the last epidemics reported in regions using pertussis acellular vaccines, isolates deficient for vaccine antigens, ...
متن کاملAntibody responses to the Bordetella pertussis virulence factor P.69 Pertactin
Bordetella pertussis, the causative agent of whooping cough, is re-emerging in several countries with a traditional high vaccine uptake. Analysis of clinical isolates revealed antigenic divergence between vaccine strains and circulating strains with respect to the B. pertussis virulence factor P.69 Pertactin. Polymorphisms in P. 69 Pertactin are mainly limited to regions comprised of amino acid...
متن کاملGenotypic variation in the Bordetella pertussis virulence factors pertactin and pertussis toxin in historical and recent clinical isolates in the United Kingdom.
The reemergence of pertussis has been reported in several countries despite high vaccination coverage. Studies in The Netherlands and Finland have investigated polymorphism in the genes coding for two important virulence factors of Bordetella pertussis, pertactin and pertussis toxin, and identified the emergence and subsequent dominance in circulating strains of pertactin and toxin variants not...
متن کاملPolymorphism in Bordetella pertussis pertactin and pertussis toxin virulence factors in the United States, 1935-1999.
To elucidate the potential role of the etiologic agent in recent increases of pertussis incidence in the United States, we studied the polymorphism in pertactin and pertussis toxin, which are Bordetella pertussis proteins important for pathogenesis and immunity. We sequenced regions of their genes (prn and ptx) in 152 B. pertussis strains isolated from 1935 through 1999 and identified 2 prn seq...
