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.

Evaluation of PCR for Diagnosis of Bordetella pertussis and Bordetella parapertussis Infections [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACT PCR, using primers PIp1 and PIp2, was evaluated for the detection of DNA from Bordetella pertussis in bacterial strains and in nasopharyngeal samples from patients with a cough lasting at least 7 days. The assay could detect DNA from 6 CFU of B.

CLINICAL CASE REPORT: PERTUSSIS INFECTION FOLLOWED BY A PARAPERTUSSIS INFECTION IN THE SAME CHILD

Problems of Infectious and Parasitic Diseases
Whooping cough is a vaccine-preventable, acute respiratory disease caused by the gram-negative bacterium Bordetella pertussis. In recent years there has been a worldwide reccurrence of pertussis infection.

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).

Structural and functional specialization of Bordetella pertussis DsbA for pertussis toxin folding

Protein Science, Volume 35, Issue 1, January 2026.
Abstract Disulphide bonds (Dsbs) are essential for the folding, stability, and function of many secreted and membrane‐associated proteins in bacteria. In Gram‐negative species, these bonds are introduced by the Dsb enzyme family, with DsbA acting as the primary thiol oxidase.

Patterns of Bordetella parapertussis Respiratory Illnesses: 2008-2010 [PDF]

Clinical Infectious Diseases, 2011
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.

Causes and Seasonality of Upper Respiratory Infections in Adults in Lesotho (2021–2022) (CORIAL)

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2026, Issue 1, 2026.
Background Upper respiratory tract infections cause morbidity and a high burden on healthcare systems worldwide, especially in low‐ and lower middle‐income countries. Recent studies throughout Africa indicate seasonal patterns that deviate from those previously described in settings with temperate climates.

Comparison of Bordetella species identification among differing rt-PCR assays in the United States

Microbiology Spectrum
In the United States, the general laboratory method for diagnosing pertussis, caused by Bordetella pertussis, is real-time PCR (rt-PCR) targeting insertion sequence 481 (IS481).

Improvement of Mycoplasma pneumoniae–Associated Acute Cerebellar Ataxia and Possible Encephalopathy After Intravenous Immunoglobulin

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Mycoplasma pneumoniae (M. pneumoniae) can cause acute postinfectious cerebellar ataxia and encephalitis/encephalopathy. Although ataxia can be self‐limited, prolonged duration of symptoms and long‐term neurological sequelae that persist for months or more are associated with both conditions.

Nucleotide sequence homology to pertussis toxin gene in Bordetella bronchiseptica and Bordetella parapertussis [PDF]

Infection and Immunity, 1987
Multiple strains of Bordetella parapertussis and B. bronchiseptica were examined for the presence of nucleotide sequences which hybridized with a cloned 4.5-kilobase (kb) fragment of B. pertussis DNA containing the genes responsible for pertussis toxin expression. All six B.
