The BvgAS Regulon of Bordetella pertussis

open access: yesmBio, 2017
Nearly all virulence factors in Bordetella pertussis are activated by a master two-component system, BvgAS, composed of the sensor kinase BvgS and the response regulator BvgA.

The importance of Bordetella pertussis strains which do not produce virulence factors in the epidemiology of pertussis

open access: yesPostępy Higieny i Medycyny Doświadczalnej, 2017
Bordetella pertussis strains, which have lost the ability to produce antigens, such as pertactin - Prn, pertussis toxin - Ptx, filamentous haemagglutinin - FHA, fimbriae type 2 and 3 - Fim 2 and 3, tracheal colonization factor - TcfA, have recently been isolated in countries with a high vaccination coverage.

Phylogeny, Synteny, and Distribution of Type III Secretion Systems in Burkholderia cenocepacia: A Closer Look Into Host Span

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
T3SS is a dedicated machinery that mediates interactions between bacteria and eukaryotic cells, providing a functional interface in pathogenic or symbiotic associations. Phylogenetic analyses and T3SS‐gene synteny revealed nine gene clusters, with no needle protein gene (sctF). However, an orphan CDS encoding a putative SctF was found.

Significance of Bordetella bronchiseptica in Respiratory Tract Infections of Canines

open access: yesInternational Journal of Bio-Resource and Stress Management
Bordetella bronchiseptica is one of the major pathogens affecting canine respiratory tract. The agent is transmitted through aerosol mode, contact with contaminated faces or urine as well as through infected fomites. The agent affects all age groups and

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

open access: yesJournal 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.

Soil Properties Induced Changes in the Microbial Communities Associated With Potato Tubers Grown in Different Lowland Fields of Northern Thailand

open access: yesMicrobiologyOpen, Volume 14, Issue 5, October 2025.
Microbial communities on potato tubers in northern Thailand were studied with 16S and ITS amplicon sequencing. It was found that soil pH and organic matter are key drivers of bacterial and fungal composition, affecting the balance between pathogens and beneficial microbes.

Practical Application of Disease Risk Assessment in Native Species Reintroductions: A Case Study of a European Wildcat (Felis silvestris) Population Reinforcement in the Cairngorms National Park

open access: yesMammal Review, Volume 55, Issue 4, October 2025.
Disease risk assessment was conducted for the Saving Wildcats reintroduction project of captive‐bred European Wildcats (Felis silvestris) to the Cairngorms National Park. Hazards were identified, and appropriate pre‐and post‐release mitigation strategies were identified and implemented, illustrating the direct conservation application and significance ...
