Inverse relationship between genetic diversity and epigenetic complexity [PDF]
, 2008 Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutral Theory’, which however remains an ...

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.

Saliva and Anterior Nasal Samples for Detecting Respiratory Viruses in Children
APMIS, Volume 133, Issue 11, November 2025.ABSTRACT For detecting respiratory viruses, a nasopharyngeal swab sample for polymerase chain reaction (PCR) assays has been the benchmark. Less discomfort related to sampling is requested especially for children, and thus other sample types have been suggested.

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 ...

The C-value enigma and timing of the Cambrian explosion
, 2008 The Cambrian explosion is a grand challenge to science today and involves multidisciplinary study. This event is generally believed as a result of genetic innovations, environmental factors and ecological interactions, even though there are many ...

Influenza and Other Respiratory Viruses, Volume 19, Issue 10, October 2025.ABSTRACT Background Human metapneumovirus (hMPV) has been increasingly recognized as a major contributor to respiratory infections in all age groups. Owing to its recent discovery, available data on the burden of hMPV in adults are still scant and heterogeneous.

Zhurnal mikrobiologii, epidemiologii i immunobiologii, 1981 The fatty acid composition of 3 B. pertussis strains and 2 B. parapertussis strains grown on casein-carbon agar (CCA) with 8% of sheep blood added and without blood, as well as B. parapertussis strain grown on beef-extract agar (BEA) has been studied by gas chromatography. The fatty acid profiles characteristic of B. pertussis and B. parapertussis were
