Shigella flexneri Regulation of ARF6 Activation during Bacterial Entry via an IpgD-Mediated Positive Feedback Loop

open access: yesmBio, 2015
Entry into cells is critical for virulence of the human bacterial pathogens Shigella spp. Shigella spp. induce membrane ruffle formation and macropinocytic uptake, but the events instigating this process are incompletely understood. The host small GTPase

Yersinia enterocolitica O:3 Outer Membrane Vesicles as a Platform for Complement Activation

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
Basic characteristics and biological activity of outer membrane vesicles (OMVs) secreted by Yersinia enterocolitica O:3 (YeO3), depending on LPS chemotype and growth temperature. ABSTRACT Lipopolysaccharide (LPS) is the major component of the outer membrane vesicles (OMVs) of Gram‐negative bacteria.

Genomic insights into Shigella species isolated from small ruminants and manure in the North West Province, South Africa

open access: yesApplied Microbiology and Biotechnology
This study investigated Shigella species’ antibiotic resistance patterns and genomic characteristics from small ruminants and manure collected in Potchefstroom, North West, South Africa. Whole genome sequencing was used to determine resistome profiles of

Antimicrobial resistance patterns and prevalence of class 1 and 2 integrons in Shigella flexneri and Shigella sonnei isolated in Uzbekistan

open access: yesGut Pathogens, 2010
Background Shigella is a frequent cause of bacterial dysentery in the developing world. Treatment with effective antibiotics is recommended for shigellosis, but options become limited due to globally emerging resistance.

The formin FHOD1 and the small GTPase Rac1 promote vaccinia virus actin-based motility [PDF]

open access: yes, 2013
Vaccinia virus dissemination relies on the N-WASP– ARP2/3 pathway, which mediates actin tail formation underneath cell-associated extracellular viruses (CEVs).

Microbiota Composition Shaped by Seasonal Variation and Environmental Compartments Affects the Abundance of Antimicrobial‐Resistant Bacteria in Indonesian Aquaculture

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Antibiotics reshape fish gut microbiota, promoting antimicrobial‐resistant bacteria (ARB) emergence. In the dry season, ARB accumulate in water and dominate a specific niche. Wet‐season hydrological changes introduce new bacteria, disturb native communities and drive shifts in AMB abundance and the emergence of novel resistant taxa across compartments.

Identification of Shiga-Toxin-Producing Shigella Infections in Travel and Non-Travel Related Cases in Alberta, Canada

open access: yesToxins, 2021
It has long been accepted that Shiga toxin (Stx) only exists in Shigella dysenteriae serotype 1. However, in recent decades, the presence of Shiga toxin genes (stx) in other Shigella spp. have been reported. We screened 366 Shigella flexneri strains from

From Lake Victoria to the Tap: Antibiotic Resistance and Pathogenic Contamination of Kisumu City Water Supply and Wastewater Network

open access: yesTropical Medicine &International Health, Volume 31, Issue 4, Page 547-559, April 2026.
ABSTRACT Waterborne diseases and antimicrobial resistance (AMR) pose mounting public health threats across sub‐Saharan Africa, particularly in rapidly urbanising regions dependent on untreated or poorly treated surface waters. This study applied shotgun metagenomic sequencing to characterise microbial communities, virulence factors and antibiotic ...

Genetic Dissection of the Signaling Cascade that Controls Activation of the Shigella Type III Secretion System from the Needle Tip [PDF]

open access: yes, 2016
Many Gram-negative bacterial pathogens use type III secretion systems (T3SSs) for virulence. The Shigella T3SS consists of a hollow needle, made of MxiH and protruding from the bacterial surface, anchored in both bacterial membranes by multimeric protein
