Pertussis with severe pulmonary hypertension in a newborn with good outcome - case report Infecção por Bordetella pertussis com hipertensão pulmonar grave num recém -nascido com boa evolução clínica - Caso clínico

Revista Portuguesa de Pneumologia, 2008
In spite of the availability and widespread use of vaccines, pertussis is far from controlled. Newborns and infants too young to be fully vaccinated, born from mothers with low antibody titers to Bordetella pertussis, are highly susceptible to infection ...

Four single-basepair mutations in the ptx promoter of Bordetella bronchiseptica are sufficient to activate the expression of pertussis toxin

Scientific Reports, 2021
Secretion of pertussis toxin (PT) is the preeminent virulence trait of the human pathogen Bordetella pertussis, causing whooping cough. Bordetella bronchiseptica, although it harbors an intact 12-kb ptx–ptl operon, does not express PT due to an inactive ...

The Effect of Physical Disability on Employment

Scottish Journal of Political Economy, Volume 73, Issue 1, February 2026.
ABSTRACT The relationship between physical disability and employment is explored using microdata for older working‐age women in the 2016 Irish Census of Population and historical data on the incidence of infectious diseases. Two‐stage least squares and recursive bivariate probit estimations are employed to account for the potential endogeneity of ...

Pertactin-Negative and Filamentous Hemagglutinin-Negative Bordetella pertussis, Australia, 2013–2017

Emerging Infectious Diseases, 2019
During the 2008–2012 pertussis epidemic in Australia, pertactin (Prn)–negative Bordetella pertussis emerged. We analyzed 78 isolates from the 2013–2017 epidemic and documented continued expansion of Prn-negative ptxP3 B. pertussis strains.

Bacterial outer membrane vesicles and vaccine applications

, 2014
Vaccines based on outer membrane vesicles (OMV) were developed more than 20 years ago against Neisseria meningitidis serogroup B. These nano-sized structures exhibit remarkable potential for immunomodulation of immune responses and delivery of “self ...

Genomics of Bordetella pertussis toxins

International Journal of Medical Microbiology, 2000
Bordetella pertussis, the etiologic agent of whooping cough, produces numerous toxins including pertussis toxin (PTX), adenylate cyclase toxin (AC), dermonecrotic toxin (DNT) and tracheal cytotoxin (TCT). PTX is composed of five different subunits organised in a typical A-B type structure of which the A part possesses an enzymatic ADP ...

Phage‐Mediated Presentation of a Conserved HA2 Epitope From Influenza A Virus Elicits Significant IgY Antibody Responses in Broiler Chickens

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
The conserved region of HA2 peptide of Influenza A virus was expressed on the surface of Protein VIII from M13 phage. Immunization of broiler chickens by this hybrid phage showed high levels of antibody responses, highlighting its potential as a promising tool for universal vaccine development against Influenza A virus.

Understanding immunity differences induced by whole cell and acellular pertussis vaccines in a paediatric population: Immunity differences between pertussis vaccines

, 2021
Bordetella pertussis causes whooping cough, a life-threatening disease in infants. Both whole cell (wP) and acellular (aP) vaccines are used for infant immunisation with aP providing less robust long-term population protection.
