Differential and Temporal Immunomodulation of alpha4 Integrins on CD4+ Memory Cells by Bordetella pertussis and Bordetella parapertussis [PDF]

, 2012
Pertussis, caused by Bordetella pertussis (B. pertussis), is reemerging worldwide due to vaccine inefficacy. The hallmarks of infection are extreme lymphocytosis and delayed recovery, which are partially associated with pertussis toxin.

Infants hospitalized for Bordetella pertussis infection commonly have respiratory viral coinfections [PDF]

, 2017
Background: Whether viral coinfections cause more severe disease than Bordetella pertussis (B. pertussis) alone remains unclear. We compared clinical disease severity and sought clinical and demographic differences between infants with B.

Incidence of RSV‐ and Influenza‐Associated Hospitalizations With Community‐Acquired Pneumonia and Other Acute Respiratory Infection Among Adults in Japan in 2022–2024: APSG‐J2 Study

Influenza and Other Respiratory Viruses, Volume 20, Issue 3, March 2026.
ABSTRACT Background Quantifying the burden of respiratory syncytial virus (RSV) in adults is challenging compared to influenza, and data among older adults remain scarce in Japan. Country‐specific evidence is essential to support RSV vaccination policy.

Experimental pneumonia induced by a Bordetella parapertussis-like organism in the ovine and murine lung : a thesis presented in partial fulfillment (70%) of the requirements for the degree of Master of Philosophy in Veterinary Pathology at Massey University [PDF]

, 1987
Thirty-four specific pathogen-free (SPF) Swiss mice were intranasally inoculated with a suspension containing about 3 x 10 7 colony-forming units (CFU)/ml of a B. parapertussis-like organism isolated from pneumonic ovine lung.

Severe pertussis infection in infants less than 6 months of age: clinical manifestations and molecular characterization [PDF]

, 2017
We conducted a study to determine the main traits of pertussis among unimmunized infants less than 6 months of age. From August 2012 to March 2015, 141 nasopharyngeal aspirates (NPAs) were collected from infants with respiratory symptoms attending 2

Torque Teno Virus Levels During Viral Respiratory Infections: The Interplay With Immune Dysregulation and Coagulopathy Biomarkers

Journal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Torque teno virus (TTV) is a ubiquitous, nonenveloped DNA virus of the Anelloviridae family and a proposed surrogate marker of immune competence. Although nonpathogenic, its replication reflects host immune status and is associated with immune dysregulation during respiratory viral infections (RVIs).
