Assembly and arrangement of the type three secretion system of "yersinia enterocolitica" [PDF]

, 2014
The type three secretion system (T3SS) is a bacterial weapon found in many Gram-negative bacteria. It consists out of a needle like structure called injectisome, which enables bacteria to inject effector proteins into eukaryotic cells. The injectisome is

A pbpB1 mutation causing reduced β-lactam susceptibility in clinical Listeria monocytogenes isolates

Emerging Microbes and Infections
Listeriosis is a severe foodborne infection and associated with high mortality. Treatment is based on ampicillin, amoxicillin or penicillin, often combined with gentamicin, but meropenem is also used occasionally.

The cell cycle regulator GpsB functions as cytosolic adaptor for multiple cell wall enzymes

Nature Communications, 2019
GpsB is a cytosolic protein that modulates bacterial cell wall synthesis by interacting with cytoplasmic domains of peptidoglycan synthases. Here, Cleverley et al.

Cell Shape and Antibiotic Resistance Are Maintained by the Activity of Multiple FtsW and RodA Enzymes in Listeria monocytogenes

mBio, 2019
Rod-shaped bacteria have two modes of peptidoglycan synthesis: lateral synthesis and synthesis at the cell division site. These two processes are controlled by two macromolecular protein complexes, the elongasome and divisome. Recently, it has been shown

Genome-wide insights into population structure and host specificity of Campylobacter jejuni

Scientific Reports, 2021
The zoonotic pathogen Campylobacter jejuni is among the leading causes of foodborne diseases worldwide. While C. jejuni colonises many wild animals and livestock, persistence mechanisms enabling the bacterium to adapt to host species' guts are not fully ...

Attachment of Enterohemorrhagic Escherichia coli to Host Cells Reduces O Antigen Chain Length at the Infection Site That Promotes Infection

mBio, 2021
Many enteropathogenic bacteria express a needle-like type III secretion system (T3SS) that translocates effectors into host cells promoting infection.

Pathophysiology of the gut–eye axis in a Sjögren's disease‐like dry eye mouse model: An exploratory evaluation of dietary heat‐treated Enterococcus faecalis FK‐23

Experimental Physiology, EarlyView.
Abstract Sjögren's disease is an autoimmune disease characterized by severe dry eye, but its pathophysiology remains unclear. Non‐obese diabetic (NOD) mice develop Sjögren's disease‐like dry eye prior to the onset of diabetes. Although intestinal immune abnormalities precede diabetes in NOD mice, their relationship to dry eye remains poorly understood.

Characterisation of Typical Enteropathogenic Escherichia coli (tEPEC) and bfpA Genes From Five Bat Species Reveals Australian Pteropus Spp. Are Natural tEPEC Hosts

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This study revealed that Australia's five Pteropus bat species are all natural hosts of typical Enteropathogenic Escherichia coli (tEPEC)—historically considered a human‐specific pathogen. Across the five Pteropus spp., tEPEC prevalence ranged between 14.2% and 37.0%, with 18 bat‐specific tEPEC strain types and 24 bat‐specific bfpA allele types ...

Three metabolic pathways replenishing the one-carbon pool collectively support growth and virulence of Listeria monocytogenes

eLife
The bacterium Listeria monocytogenes can grow in the cytoplasm of infected human cells, but there it relies on specific biosynthetic pathways for intracellular nutrient supply.

Diversity and antimicrobial resistance of Salmonella enterica serovars in surface river water and sediment

Revista de Ciências Agroveterinárias, 2021
This study aimed to evaluate the contamination by Salmonella sp. in the Capinzal River, to determine the prevalent serovars, patterns of antimicrobial resistance, and the genetic relationships between the serovars identified.
