Pertussis in children in the İstanbul Faculty of Medicine: results for four years

The Turkish Journal of Pediatrics, 2014
We investigated the frequency of pertussis among children in the İstanbul Faculty of Medicine Hospital during a period of four years. Clinical specimens were obtained from children who exhibited symptoms of whooping cough; a portion of the cases ...

Detection of Bordetella parapertussis in Clinical Samples Based on Real-Time PCR and Culture [PDF]

Background & Objectives: Parapertussis is a bacterial illness that is similar to pertussis (whooping cough) but is typically milder than pertussis. Parapertussis is caused by the bacterium Bordetella parapertussis.

Functional effects of α4 integrins on migration and adhesion of blood leukocytes from B. pertussis and B. parapertussis infections in vitro.

, 2013
(A) Migration of blood leukocytes from B. pertussis and B. parapertussis infections at 5 days p.i. through vascular cell adhesion molecule 1 (VCAM-1)-coated or BSA-coated transwells, in response to stromal cell-derived factor-1 alpha (SDF-1α) or control ...

O-antigen blocks B. pertussis vaccine-induced, antibody-mediated phagocytosis of B. parapertussis.

, 2013
Freshly isolated human peripheral blood PMNs were incubated for 20 min or 1 h and 20 min with GFP-expressing B. pertussis (black), B. parapertussis (white), or O-antigen deficient B. parapertussis (hatched), that are opsonized with serum from aP, wP, wPP-

Bordetella parapertussis survives inside human macrophages in lipid raft-enriched phagosomes [PDF]

, 2019
Bordetella parapertussis is a human pathogen that causes whooping cough. The increasing incidence of B. parapertussis has been attributed to the lack of cross protection induced by pertussis vaccines. It was previously shown that B. parapertussis is able

Differential expression of virulence factor genes in B. pertussis and B. parapertussis in response to 5% CO₂ conditions.

, 2012
qRT-PCR analysis was performed on B. pertussis (A) and B. parapertussis (B) grown in atmospheric or elevated CO2 conditions. Fold-change expression (FCE) in B. pertussis and B.

B. parapertussis inhibits PMA-induced NETs through a Bvg-regulated factor.

, 2017
Neutrophils were incubated with virulent B. parapertussis (Bvg+ Bpp), formalin inactivated B. parapertussis (FK Bpp), avirulent B. parapertussis (Bvg- Bpp) (MOI 10), or DPI for 30 min at 37°C prior to PMA treatment.

Immunobiological properties of circulating Bordetella pertussis strains: Candidate strains for production of pertussis vaccines

Биопрепараты: Профилактика, диагностика, лечение
INTRODUCTION. One of the reasons for increased pertussis cases is the pathogen adapting to the existing collective immunity formed under conditions of vaccine prophylaxis.
