Shigella sonnei O-Antigen Inhibits Internalization, Vacuole Escape, and Inflammasome Activation

open access: yesmBio, 2019
Two Shigella species, Shigella flexneri and Shigella sonnei, cause approximately 90% of bacterial dysentery worldwide. While S. flexneri is the dominant species in low-income countries, S.

Structural and functional insights into Pseudomonas aeruginosa ApaH, a diadenosine tetraphosphatase crucial for bacterial virulence

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Infections by Pseudomonas aeruginosa are a major cause of severe morbidity and mortality in immunocompromised patients and people with cystic fibrosis, largely due to the pathogen's ability to resist antibiotic treatment and to deploy multiple virulence strategies that promote persistence in the host.

Long‐Term Effects of a Dietary Humic Substance–Butyrate Blend, and Yeast Cell Wall on Growth Performance, Immune Status and Gut Microbiota of Juvenile Channel Catfish Ictalurus punctatus

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT This study evaluated the long‐term effects of a dietary humic substance and butyrate blend (HSB) alone or with yeast cell wall (Beta‐MOS) in channel catfish. Around 1440 fish (31.31 ± 0.24 g) were distributed among 12 outdoor tanks in a pond‐supplied flow‐through design. Four dietary treatments were evaluated in triplicate: Diets containing no

MECHANISMS OF COLONIZATION RESISTANCE TO SHIGELLA FLEXNERI

open access: yes, 2016
Shigella flexneri is an enteric bacterial pathogen responsible for shigellosis. Components of the commensal microbiota promote colonization resistance in mice and antibiotic treatment is required for susceptibility to S. flexneri infection.

[Growth dyssymmetry of Shigella flexneri 6(762 S) cells].

open access: yesZhurnal mikrobiologii, epidemiologii i immunobiologii, 1982
Dyssymmetry in the growth of the initial and secondary shigella cells at early stages of the formation of microcolonies has been revealed by the method of dynamic morphometry in serial photographs obtained by time-lapse microfilming. Electron-microscopic autoradiography has allowed revealing dyssymmetry in the assimilation of exogenous H3-thymidine, H3-

IcsB inhibits early recruitment of LC3 around S. flexneri that are cytoplasmic.

open access: yes, 2014
(A) LC3, NDP52, ubiquitin and P62 recruitment in the vicinity of wild-type pflag (WT), ΔicsB pflag, or ΔicsB pIcsB-flag S. flexneri, at 40 min. of infection of HeLa cells that had been transfected with LC3-GFP or labeled with antibodies to other ...

[Morphological characteristics of phagolysis of S- and R-forms of Shigella flexneri].

open access: yesZhurnal mikrobiologii, epidemiologii i immunobiologii, 1983
The differences in the character and time of the lysis of S. flexneri S- and R-mutant cells have been detected by the method of time-lapse microfilming. The asymmetry of the phagolysis of the S-form of shigellae infected with phage F1 has been revealed.
