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.

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.

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.

Evaluation of the ELITe InGenius and Bordetella ELITe MGB Kit for the detection and identification of B. pertussis, B. parapertussis and B. holmesii

Diagnostic Microbiology and Infectious Disease
Bordetella pertussis is the causative pathogen of whooping cough or pertussis, a contagious respiratory disease. Aside from serodiagnosis, laboratory confirmation of pertussis is done through PCR, as B. pertussis is difficult to culture. The ELITe InGenius instrument (ELITechGroup, France) with accompanying Bordetella ELITe MGB Kit was evaluated ...

Standard Operating Procedure for Real-time PCR Detection and Identification of Bordetella pertussis, B. parapertussis, and B. holmesii using AB7500 v1 [PDF]

, 2017
The appropriate use of clinically accurate diagnostic tests is essential for the detection of pertussis, a poorly controlled vaccine-preventable disease. The purpose of this study was to estimate the sensitivity and specificity of different diagnostic criteria including culture, multi-target polymerase chain reaction (PCR), anti-pertussis toxin IgG ...
