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.

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.

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.

Identification of a CO2 responsive regulon in Bordetella. [PDF]

PLoS ONE, 2012
Sensing the environment allows pathogenic bacteria to coordinately regulate gene expression to maximize survival within or outside of a host. Here we show that Bordetella species regulate virulence factor expression in response to carbon dioxide levels ...

Severe Necrotizing Community‐Acquired Pneumonia and Bilateral Empyema in an Immunocompetent Patient due to Fusobacterium necrophorum

Case Reports in Pulmonology, Volume 2026, Issue 1, 2026.
Necrotizing pneumonia and empyema caused by Fusobacterium necrophorum are uncommon. The classical presentation of Lemierre′s syndrome, characterized by pharyngotonsillitis and internal jugular vein thrombosis, is not always observed, and incomplete and atypical variants can cause diagnostic uncertainty and delay in treatment.

Rebound of Respiratory Virus Activity and Seasonality to Pre‐Pandemic Patterns

Journal of Medical Virology, Volume 97, Issue 11, November 2025.
ABSTRACT The emergence of SARS‐CoV‐2 and the implementation of non‐pharmaceutical interventions (NPIs) profoundly disrupted the transmission dynamics of respiratory viruses, altering their epidemiology and seasonality. However, comprehensive long‐term data on these shifts and their post‐pandemic implications remain limited.
