Pathogen adaptation has contributed to the resurgence of pertussis. To facilitate our understanding of this adaptation we report here 11 completely closed and annotated Bordetella pertussis genomes representing the pandemic ptxP3 lineage. Our analyses included six strains which do not produce the vaccine components pertactin and/or filamentous hemagglutinin.

Insertion sequences (IS) represent mobile genetic elements that have been shown to be associated with bacterial evolution and adaptation due to their effects on genome plasticity. In , the causative agent of whooping cough, the numerous IS elements induce genomic rearrangements and contribute to the diversity of the global population. Previously, we have shown that the majority of IS-specific endogenous promoters induce the synthesis of alternative transcripts and thereby affect the transcriptional landscape of .

The dynamics of the genetic diversity of pathogens, including the emergence of lineages with increased fitness, is a foundational concept of disease ecology with key public-health implications. However, the identification of such lineages and estimation of associated fitness remain challenging, and is rarely done outside densely sampled systems. Here we present phylowave, a scalable approach that summarizes changes in population composition in phylogenetic trees, enabling the automatic detection of lineages based on shared fitness and evolutionary relationships.

In the post-pandemic era, research on respiratory diseases should refocus on pathogens other than the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Respiratory pathogens, highly infectious to children, with to different modes of infection, such as single-pathogen infections and co-infections. Understanding the seasonal patterns of these pathogens, alongside identifying single infections and co-infections and their impact on the pediatric immune status, is crucial for clinical diagnosis, treatment, and prognosis in children.

Pertussis remains a significant public health concern despite effective vaccines due to diagnostic challenges and symptom overlap with other respiratory infections. This study assesses the prevalence of using advanced polymerase chain reaction (PCR) testing and examines the clinical outcomes over a one-month follow-up. We conducted a cross-sectional study at the University Hospital of Larissa, Greece, from April to June 2024, collecting 532 nasopharyngeal swabs from patients with respiratory symptoms.
