Diverse Microbial Communities Assemble on Both Recalcitrant and Labile Carbon Sources

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Taxonomically and functionally distinct communities assemble on cellulose and its monomer, glucose. Although single carbon sources were provided, high and comparable diversity was maintained in both environments, supported by extensive cross‐feeding and scavenging. However, glucose supported higher biomass than cellulose and selected generalists, while

Humoral immunity to adhesins and toxins of the pertussis pathogen in mice immunized with experimental acellular pertussis vaccines from biofilm and planktonic cultures of Bordetella pertussis

Журнал микробиологии, эпидемиологии и иммунобиологии
Introduction. Whooping cough remains an urgent health problem worldwide, including in countries with high vaccination rates, where, since the 1990s, there has been an increase in the incidence of whooping cough, an increase in the severity of the disease

An N‐acetyltransferase‐MAPK fusion protein modulates developmental reprogramming in Physcomitrium patens

New Phytologist, Volume 251, Issue 1, Page 321-339, July 2026.
Summary We discovered a previously uncharacterized moss‐specific protein, Rosetta NATD‐MAPK 1 (RAK1) in Physcomitrium patens, which uniquely integrates MAP kinase (MAPK)‐dependent signaling with N‐acetyltransferase activity. Through phenotypical and biochemical analyses, we characterized RAK1 function in the regulation of the 2D‐to‐3D growth transition.

Effect of FHA and Prn on Bordetella pertussis colonization of mice is dependent on vaccine type and anatomical site.

PLoS ONE, 2020
Bordetella pertussis vaccine escape mutants that lack expression of the pertussis antigen pertactin (Prn) have emerged in vaccinated populations in the last 10-20 years.

Serum proteases prevent bacterial biofilm formation: role of kallikrein and plasmin

Virulence, 2021
Biofilm formation is a general strategy for bacterial pathogens to withstand host defense mechanisms. In this study, we found that serum proteases inhibit biofilm formation by Neisseria meningitidis, Neisseria gonorrhoeae, Haemophilus influenzae, and ...

RNF213 Is an Interferon‐Stimulated Gene That Targets Influenza A Virus NP and Activates MDA5 to Restrict Infection

Advanced Science, Volume 13, Issue 31, 4 June 2026.
RNF213 is characterized as a dual‐functional antiviral effector. It directly mediates the degradation of the influenza A virus nucleoprotein (NP) while simultaneously activating the MDA5‐mediated innate immune signaling pathway. This coordinated response establishes a powerful host defense system against viral infection. ABSTRACT Influenza A virus (IAV)

Immunoglobulin A antibodies to pertussis toxin and filamentous hemagglutinin in saliva from patients with pertussis [PDF]

Journal of Clinical Microbiology, 1990
Immunoglobulin A (IgA) antibodies against pertussis toxin (PT) and filamentous hemagglutinin (FHA) in 181 saliva samples obtained during various stages of pertussis from 112 patients were determined. Saliva samples obtained within 5 days after the onset of symptoms did not have detectable IgA antibodies against either of the two antigens.

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...
