Photocatalytic biocidal effect of copper doped TiO2 nanotube coated surfaces under laminar flow, illuminated with UVA light on Legionella pneumophila.

PLoS ONE, 2020
Legionella pneumophila can cause a potentially fatal form of humane pneumonia (Legionnaires' disease), which is most problematic in immunocompromised and in elderly people.

Coxiella burnetii Blocks Intracellular Interleukin-17 Signaling in Macrophages [PDF]

, 2018
Coxiella burnetii is an obligate intracellular bacterium and the etiological agent of Q fever. Successful host cell infection requires the Coxiella type IVB secretion system (T4BSS), which translocates bacterial effector proteins across the vacuole ...

Contamination of Legionella pneumophila in metro cooling tower water and its influencing factors in a city

环境与职业医学
BackgroundThe detection rates of Legionella pneumophila in metro cooling tower water in various cities are relatively high, while studies investigating the trends of Legionella pneumophila pollution and analyzing its influencing factors are still limited.

Global analysis of gene expression reveals mRNA superinduction is required for the inducible immune response to a bacterial pathogen. [PDF]

, 2017
The inducible innate immune response to infection requires a concerted process of gene expression that is regulated at multiple levels. Most global analyses of the innate immune response have focused on transcription induced by defined immunostimulatory ...

Type VI secretion: a beginner's guide [PDF]

, 2008
Type VI secretion is a newly described mechanism for protein transport across the cell envelope of Gram-negative bacteria. Components that have been partially characterised include an IcmF homologue, the ATPase ClpV, a regulatory FHA domain protein and ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Ecological distribution of Legionella pneumophila [PDF]

Applied and Environmental Microbiology, 1981
Bacteria were concentrated 500-fold from 20-liter water samples collected from 67 different lakes and rivers in the United States. The data suggest that Legionella pneumophila is part of the natural aquatic environment and that the bacterium is capable of surviving extreme ranges of environmental conditions.

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]

, 2020
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Legionella pneumophila-Derived Outer Membrane Vesicles Promote Bacterial Replication in Macrophages. [PDF]

PLoS Pathogens, 2016
The formation and release of outer membrane vesicles (OMVs) is a phenomenon of Gram-negative bacteria. This includes Legionella pneumophila (L. pneumophila), a causative agent of severe pneumonia. Upon its transmission into the lung, L.
